San Diego County CA - My gauge is in the western Elfin Forest area about half way between Encinitas and Escondido and south of San Marcos.
Elevation 777 feet.
Friday, September 10, 2021 - 4:41 PM - A Yesterday a small thunderstorm formed near Chula Vista and move north northwest towards Encinitas. I captured some excellent lightning photos and will post here when I get a chance to process them. I felt one (!) raindrop here. Carlsbad received .01", none of the other sites I follow recorded anything. I heard a report of some heavy rain in the Solana Beach area. La Jolla received .11" and Del Mar .05". The storm produced one of the best lightning shows I've ever seen!
Tuesday, August 31, 2021 - 9:27 AM - A slowly north moving convergence zone with inputs from the NE and S brought .04" of rain here w/ lighting and thunder to the east. NWS total not yet posted. Yesterday, storms were well to the east. Yesterday's NWS totals as of 6:30 PM: Nothing in the locales I follow here. Mt. Woodson had .13", Alipine .05", Puerta La Cruz led the mountains with .78"
Sunday, August 29, 2021 - 8:05 PM - NWS totals as of 4:00 PM: Encinitas .00", San Marcos .00", Escondido .03", San Diego .00", La Mesa .00", Ramona .06". Barona led the county with 1.31"!
Sunday, August 29, 2021 - 4:23 PM - Lighting, thunder, wind and a few large raindrops from monsoonal storms from the east. So far a trace.
Monday, August 23, 2021 - 9:34 PM - Bit behind here. On Saturday August 21 we had .05" of mostly drizzle and a little light rain. NWS totals as of 4:10 PM Saturday: Encinitas .07", San Marcos .00", Escondido .03", San Diego .00" (trace), La Mesa .00", Ramona .06".On Sunday August 22 we had .02" of drizzle. The NWS did not post totals. San Diego airport had nothing.
Friday, August 20, 2021 - 10:35 AM - A trace of drizzle here Wednesday and yesterday. NWS totals for 2 days as of yesterday morning show Carlsbad with .01", nothing in the other locations I post here.
Wednesday, August 11, 2021 - 12:42 PM - In the wee hours of this morning, a surge of thunderstorms from Arizona invaded San Diego county. Quite a few places along the mountains received rain, Julian .62". San Diego Airport lucked out and was struck by a small cell. Here in Elfin Forest just a trace. NWS totals as of 5:05 AM: Encinitas .00", San Marcos .00", Escondido .00", San Diego .23" (!), La Mesa .00", Ramona .00".
Sunday, August 1, 2021 - 9:06 AM - Nice monson clouds to the east the past few days. No rain here. Finally updating the July 26 figures: Total here was .10". NWS totals as of 5:00 PM 7/26: Encinitas .06", San Marcos .06", Escondido .11", San Diego .00", La Mesa .00", Ramona .10".
Monday, July 26, 2021 - 7:15 AM - There has been a lot of excellent monsoonal weather over AZ and NM, with some eventually spilling into San Diego County. Yesterday nice clouds to the east and we had just two traces of rain here, Descanso area received over 2" in a rather isolated event. No figures from the locals I track here.
This morning rain! As of about 6:15 AM here .09" a repeat of last week although no lighting or thunder. NWS totals as of 6:00 AM: Encinitas .06", San Marcos .06", Escondido .10", San Diego .00", La Mesa .00", Ramona .10".
Monday, July 19, 2021 - 8:40 AM - Final total here for yesterday .09". NWS 24 hour totals as of 10:32 PM yesterday has Encinitas @ .07", the rest unchanged. Big Bear City 1.60"!!
Sunday, July 18, 2021 - 12:02 PM - Lightning, Thunder, Rain! Around 4:15 AM I was awakened by thunder as a line of small cells approached from the southwest, intensifying as they moved towards Oceanside. Final total here .09". NWS totals as of 8:45 AM: Encinitas .06", San Marcos .06", Escondido .03", San Diego .00", La Mesa .00", Ramona .00". Dozens of lightning flashes and some loud thunder during the storm, but very little if any wind. Oceanside ended up with .23", the leader was Rincon Springs with .44". I'm using a new version of Adobe Dreamweaver - it is so much more clunky, typing is frankly a pain in the butt, plus the spell checker doesn't work! Plus the program no longer does drag and drop of images! Have to hand-code.
Shower to the east on Friday, July 16, 2021 - No rain totals, if any, were available
Wednesday, June 30, 2021 - 9:56 PM - The forecast of thunderstorms today with locally heavy rains, predicted a few days ago, was a massive fail. Virtually nothing, a few cumulus today over the mountain ridges, small t-storms over northern Baja.
Failed Monsoonal rains - June 30, 2021 looking east from Elfin Forest
I posted the seasonal rain chart update at San Diego Rain - just 4.51" these past 12 months at the San Diego Airport. Five of the 10 driest seasonal totals have occurred in the last 20 years of 160 years of weather data.
Wednesday, June 23, 2021 - 12:27 PM - Yesterday we had a few raindrops around 2:25 PM for a scant trace of rain. This morning around 4 AM a shower loud enough to wake me passed through followed by just a few scattered raindrops. The system came up from the south, the remnants of a tropical depression. Total here about .025" or officially .02". Some areas in the county received quite a bit more! NWS totals as of 11:01 AM: Encinitas .00", San Marcos .01", Escondido .01", San Diego .01", La Mesa .06", Ramona .00". Smuggler's Gulch in the Tijuana river area received .20".
Monday, June 7, 2021 - 8:32 PM - Thick June Gloom today, patchy drizzle and one short period of light rain: .02" here. No totals provided by NWS. The SD Area 24 hours Observed Precipitation Map as of 8 PM shows Encinitas with .01" and SD Airport with a trace.
Monday, May 17, 2021 - 9:03 AM - More May Gray with some drizzle, another .03" here. NWS totals for the past 2 day as of 5:02 AM: Encinitas .02", San Marcos .11", Escondido .01", San Diego .04", La Mesa .00", Ramona .00", Julian .07". Will include Julian in the list from now on to get some SD County mountain perspective.
Sunday, May 16, 2021 - 4:58 PM - Just a touch more drizzle bringing the total to .03" plus the missing part. NWS totals as of 12:31 PM: Encinitas .00", San Marcos .10", Escondido .01", San Diego .04", La Mesa .00", Ramona .00". Oceanside leads SD County with .28". More of the same forecasted through tomorrow.
Sunday, May 16, 2021 - 11:43 AM - More May Gray drizzle and some light rain. Around 8:15 AM it rained for a couple minutes loud enough to hear it. After it stopped I went to check the gauge, disaster! I was interrupted from cleaning the overflow container yesterday and forgot about it, the components were lying on the ground. I did find a bucket, guessing from that, we received .02-.05". Just now the drizzle stopped and the clouds have lifted, about .025" in the gauge since about 8:20 AM. So overall I'd say at least .05" here this morning. NWS totals as of 9 AM: Encinitas .00", San Marcos .07", Escondido .00", San Diego .00", La Mesa .00", Ramona .00". So nearby San Marcos bears witness with the highest total in SD county as of the 9 AM list. Orange and San Bernardino counties had more.
Saturday May 15, 2021 - 12:06 PM - May Gray drizzle early morning wetting the ground, .01" in the gauge. NWS has not posted any totals and nothing showing anywhere on the NWS SD area precipitation map at https://www.cnrfc.noaa.gov/precipMaps.php?group=san&hour=24&synoptic=0.
Sunday, May 2, 2021 - 4:26 PM - Drizzle and very light rain off and on most of the morning into the afternoon. Just over .05" in the gauge. NWS 24 hour totals as of 1:47 PM: Encinitas .01", San Marcos .01", Escondido .00", San Diego .01", La Mesa .03", Ramona .00". Miramar Lake took top honors with .10".
Tuesday, April 27, 2021 - 8:57 AM - No rain fell overnight even though .1 to .25" was predicted. Yesterday .10" in the gauge, just under .05" by early yesterday morning and a little over .05" later in the morning. All of the rain was of the heavy drizzle / light rain variety. NWS 2 days totals as of 5:02 AM: Encinitas .10", San Marcos .04", Escondido .09", San Diego .05", La Mesa .07", Ramona .10". Del Mar led the SD coastal areas with .32", elsewhere Mt. Woodson .32", Lake Cuyamaca .51". Still might get a shower today. Then heat!
Friday, April 23, 2021 - 11:06 AM - Yesterday morning deep marine layer and some drizzle / fine rain, .05" in the gauge. Last night another .03" bringing the total to .08". The NWS has posted totals but for overlapping short periods and no overall totals. Doing the best I can, the overall totals since 9 PM Wednesday evening: Encinitas .02" (again!), San Marcos .05", Escondido .00", San Diego .02", La Mesa .04", Ramona .10". Meanwhile the forecasted Monday rain event is still on, numbers have been posted : 1/4 to 1/3 inch for the coastal area, 1/2 to 3/4 inland with snow in the mountains. NWS notes that forecasted figures have "trended lower", sigh.
Wednesday, April 21, 2021 - 4:42 PM - Trace of mist this morning. The NWS posted 12 hour totals as of 10 AM. Encinitas .02", the other stations zip, a repeat of April 14. No other area in SD county exceeded .02". NWS has been discussing significant rain next Monday or Monday night. Not all models agree. Hope!
Wednesday, April 14, 2021 - 1:25 PM - I have updated the Time Lapse Lichen project with this year's picture. The photo was taken on March 28. There was no update last year due to Covid-19. The lichen rebounded a bit from two years ago. This project is now 18 years old, perhaps one of the longest running lichen growth documentations in the world!
Wednesday, April 14, 2021 - 12:02 PM - Marine layer mist added about 1/2 of .01", last night, has to be counted as a trace. The NWS did post 24 hour totals as of 3:00 AM today. Encinitas came in with .02", the other stations zip. Lower Oak Flats still led the county, now with .15".
Tuesday, April 13, 2021 - 1:25 PM - A deep marine layer this morning brought heavy drizzle bordering on light rain. 03" in the rain gauge. The NWS has posted totals as of 1:01 PM today, none of the stations I post here recorded anything. The highest total in SD county: .07" at Lower Oat Flats.
Wednesday, April 7, 2021 - 2:52 PM - Methane data for 2020 is out. Page updated today. The levels jumped again last year to a new record.
Last year, thanks to the Covid-19 pandemic I was not able to update the Time Lapse Lichen project as I was not able to access the lichen location. Last week I finally got to my secret location and took photos for the 2021 year. I hope to update the page this week. Meanwhile, there is no rain in the forecast. I've been hoping for one more good rainfall before the dry season is fully upon us.
Friday, March 26, 2021 - 10:07 AM - Light showers passed through here yesterday afternoon and evening. Total here .08". Final NWS storm totals as of 9:16 AM today: Encinitas .01", San Marcos .04", Escondido .09", San Diego .04", La Mesa .24", Ramona .10". Again much higher amounts fell inland with Julian getting .67" and Lake Cuyamaca leading with 1.07".
Wednesday, March 24, 2021 - 11:06 AM - Early yesterday morning just a touch of rain here. .005" in the gauge, have to call it a trace. Final NWS storm totals as of 9:16 PM yesterday: Encinitas .00", San Marcos .00", Escondido .00", San Diego .00", La Mesa .01", Ramona .00". So La Mesa is the only one with a figure. The mountains received real rain, Descanso .37", Pine Valley .24" for example.
Tuesday, March 16, 2021 - 7:05 PM - A few showers passed over late evening and last night bringing the final storm total here to .30". Final NWS storm totals as of 10:02 AM today: Encinitas .22" (unchanged), San Marcos .20" (+.03"), Escondido .25" (+.07"), San Diego .18" (+.01"), La Mesa .24" (+.03"), Ramona .28 (+.16").
Monday, March 15, 2021 - 3:35 PM - More Rain! Frontal system went through, rain started mid-morning and ended early afternoon. Follow-up showers possible. Current total here: .28". Winds picked up with the frontal passage, feels cold and raw. Kudos for a rather accurate forecast from NWS! NWS storm totals as of 3:01 PM today: Encinitas .22", San Marcos .17", Escondido .18", San Diego .17", La Mesa .21", Ramona .12". So we are leading the local pack.
Saturday, March 13, 2021 - 9:54 AM - No rain here last night. Final total here .94". NWS storm totals as of 9:03 AM today: Encinitas .75" (unchanged), San Marcos .78" (+.01"), Escondido 1.24" (unchanged), San Diego .67" (unchanged), La Mesa .87" (unchanged), Ramona 1.14" (+.06"). Oceanside takes the coastal prize with 1.27". Palomar Mountain received 23.5" of snow!
Friday, March 12, 2021 - 5:45 PM - Last night .03" fell here bringing the storm total to .94". Yesterday was a complete bust here after early morning and today nothing except for that .03" we had last night. NWS storm totals as of 1:19 PM today: Encinitas .75" (+.01"), San Marcos .77" (+.02"), Escondido 1.24" (unchanged), San Diego .67" (unchanged), La Mesa .87" (+.04"), Ramona 1.08" (+.04"). The last couple days has been an epic cloud fest! Super clear air with instability producing cumulus practically turning into cumulonimbus with anvil heads! Plus to the east, snow is visible!
Thursday, March 11, 2021 - 11:00 AM - Had at least one heavy shower last night; this wave of showers ended early morning. Gauge now at .91" (+.51)! NWS storm totals as of 9:17 AM: Encinitas .74" (+.47"), San Marcos .75" (+.50"), Escondido 1.24" (+.75"), San Diego .67" (+.53"), La Mesa .83" (+.48"), Ramona 1.04" (+.76"). Showery pattern on a break now, last wave predicted for late this afternoon and night with some wrap around moisture for tomorrow.
Wednesday, March 10, 2021 - 4:31 PM - Been just a few widely scattered hit and mostly miss showers since morning. Total as of 4:20 PM .40" (+.03). NWS storm totals as of 2:32 PM: Encinitas .27" (+.02"), San Marcos .25" (+.01"), Escondido .49" (+.01"), San Diego .14" (+.02"), La Mesa .25" (+.04"), Ramona .28" (unchanged). Showery pattern to continue.
Wednesday, March 10, 2021 - 8:36 AM - Rain! Heavy shower went through early morning. Total as of 8:05 AM .37". NWS storm totals as of 8 AM: Encinitas .25", San Marcos .24", Escondido .48", San Diego .12", La Mesa .21", Ramona .28". Showery pattern to continue.
Tuesday, March 9, 2021 - 9:41 AM - Overnight March 7-8, .01" fell here, either in drizzle or a very light shower. NWS did not post storm totals. The predicted rain for this week is still on track - a slow moving system, 1" predicted for SD Country coasts, more in the mountains. My gauge is ready!
Thursday, March 4, 2021 - 9:57 AM - Another .02" fell overnight bringing my storm total to .91". NWS storm totals as of 9:01 AM: Encinitas .61", San Marcos .99", Escondido .65", San Diego .58", La Mesa .95", Ramona .70". Only a slight chance of showers in the official forecast for the coming week due to forecast model conflict, some models say more rain next Tuesday-Wednesday. Hope hope as February was very dry (just .17" here and .10" at SD Airport) and the dry season will be well under way by the end of April.
Wednesday, March 3, 2021 - 8:41 PM - After being way behind areas to the south, we lucked out and had a persistent micro atmospheric river center covered us for several hours mid to late afternoon and early evening. Final total here .89"! Yay! Still a few small showers offshore. NWS storm totals as of 6:46 PM: Encinitas .56", San Marcos .82", Escondido .58", San Diego .57", La Mesa .93", Ramona .58".
Still waiting for the Methane data for 2020.
Wednesday, March 3, 2021 - 12:54 PM - A nice band of rain came ashore mid morning. Unfortunately we got ripped as a gap developed which gave us early sun while dark clouds moved to our north and south. So far .06" in the gauge. NWS storm totals (going back to their old list of locations) as of 11:15 AM: Encinitas .04", San Marcos .03", Escondido .04", San Diego .07", La Mesa .10", Ramona .00".
Tuesday, February 16, 2021 - 6:20 PM - Light rain passed through here last night, didn't hear it. Had .06" in the gauge at 6 AM this morning, no follow-up showers. The NWS now has many more stations in the rainfall list. For Escondido, for example, there is a "1.5 SW Escondido", "Escondido 1", "Escondido North", "Escondido 4" and "Escondido 5". So what I'll do is post the range for a given city. NWS storm totals as of 10:28 AM: Encinitas .02-.06", Elfin Forest (no data, looks like this location not carried any more), San Marcos .05-.08", Escondido .03-.06", San Diego .06-.16", La Mesa .14-.16", Ramona .07-.17".
Friday, February 12, 2021 - 2:24 PM - First rain of February. Drizzle and light rain early this morning dropped .05" here, and then a trailing cold front and brief squall in the late morning dropped .06" more giving us a storm total of .11". NWS storm totals as of 1:01 PM: Encinitas .04", Elfin Forest (no data, zero?), San Marcos Land Fill .07", Escondido .19", SD Airport .03", La Mesa .14-.16", Ramona .19".
Saturday, January 30, 2021 - 9:55 AM - Sky clear and sunny this morning. Another .01" snuck in sometime after late afternoon yesterday, final storm total here 1.19". Total here for the month (assuming .7" for the first of the three recent storms) 2.46". My season total now 4.29". NWS storm totals as of 8:03 PM yesterday evening: Encinitas .99", Elfin Forest .82", San Marcos Land Fill .96", Escondido 1.46", SD Airport 1.03", La Mesa 1.22", Ramona .88".
That's it for January, will update the monthly file over on the Rain page shortly.
Friday, January 29, 2021 - 5:06 PM - Two more showers passed through both adding to the total here, the first .10" and the second .16", storm total now 1.18", within the forecast!
Friday, January 29, 2021 - 8:09 AM - I have updated the annual charts for San Diego Sea Levels for 2020 with added commentary.
Friday, January 29, 2021 -7:44 AM - The heralded "atmospheric river" passed through last night, starting around 11:15 PM and ending around 4 AM. It narrowed and weakened, I think a bit more than predicted, by the time it reached San Diego County, but still dropped much needed rainfall. Received .92" here, the wettest storm of the season! January has turned out to be a good month with over 2" here, all in the past week. NWS storm totals as of 7:01 AM this morning: Encinitas .79", Elfin Forest .67", San Marcos Land Fill .75", Escondido 1.10", SD Airport .73", La Mesa .80", Ramona .62". Again, lots of snow in the mountains, building the winter pack.
Tuesday, January 26, 2021 - 8:28 AM - Overnight .06" more in the range gauge, storm total here .58". Skies now clear and sunny, a few scattered cloud bands to the southwest. Yesterday was one of stormiest I can recall in terms of frequent hail, gale force winds and penetrating cold! NWS storm totals as of 4:02 AM this morning: Encinitas .23", Elfin Forest .46", San Marcos Land Fill .40", Escondido .96", SD Airport .30", La Mesa .44", Ramona 1.50 (!!)". Lots of snow in the mountains, building the winter pack: Big Bear / Lake Arrowhead both exceeded a foot.
Happily the third storm of the series is still on track with 1" predicted for the coast areas and more inland. The storm will be warmer and will melt the lower elevations snows.
Monday, January 25, 2021 - 10:09 PM - During the afternoon another .02" fell here as the strong winds continued. This evening three more cells went through each one with more hail and very strong winds, and one with some lightning and thunder! The first two also had BB sized hail, the third one had heavier small pea sized hail.
.18" more in the gauge bringing the storm total here to .52". Will post NWS figures tomorrow, they haven't been updated for a while.
Monday, January 25, 2021 - 10:03 AM - Around 9PM yesterday evening a brief shower went through, with about 1/2 minute of BB sized hail. Then from 3-4 AM today heavy rain squalls followed by very strong winds with likely gale force guests, winds continuing. Thought I'd see an inch in the gauge but due to the brevity of the squalls, total here early morning .31" and just .01" since then bringing storm total here to .32". NWS storm totals as of 8:46 AM this morning: Encinitas .16", Elfin Forest .31", San Marcos Land Fill .16", Escondido .38", SD Airport .20", La Mesa .39", Ramona .80 (!)".
Sunday, January 24, 2021 - 9:30AM - At least three more bands of showers passed here since the last post, with an additional .36" of rain. Total here for sure .64" and I'm guessing .06" more from yesterday morning's tilted gauge problem for a total of .7". Excellent start to the current wet spell! This coming Monday and Thursday will bring more. NWS storm totals as of 8:17 AM this morning: Encinitas .47", Elfin Forest .64", San Marcos Land Fill .56", Escondido .59", SD Airport .46", La Mesa .55", Ramona .68".
Saturday, January 23, 2021 - 1:08 PM - Rain! Showers last night and early morning. Found that my rain gauge was not vertical having be skewed by the recent strong winds. 0.19" in the gauge, guessing we got closer to .25". Then mid morning (after fixing the gauge), a short heavy band of rain went through adding another .09" . Right now it looks like a heavier band is approaching!
Wednesday, January 20, 2021 - 8:16 PM - I have updated the annual charts for Nitrous Oxide Levels for 2020 with added commentary. In weather news, the last couple days here have been very, very windy with east winds as a closed low passed inland to the south of here. We had just a couple drops of rain yesterday for a trace, nothing today. Also, January 15 turned out to be extraordinarily warm reaching 93 degrees here. San Diego airport at 88 broke their record for January 15 by 6 degrees! It's possible San Diego airport tied their all time high for January.
Friday, January 15, 2021 - 8:24 AM - I have updated the annual charts for Carbon Dioxide Levels for 2020 with added commentary.
Friday, January 1, 2021 - 10:07 PM - I have updated the annual chart for San Diego Temperature for 2020 with added commentary. Temperature and Arctic Sea Ice will be updated tomorrow.
Friday, January 1, 2021 - 8:52 AM - Happy New Year! First of all here are the delayed stats for the recent rain. We had .84" total thanks to a few more showers during the final night. NWS storm totals were San Diego Airport .71", Encinitas .44", San Marcos .58", Escondido .85", La Mesa .88". Pine Hills lead the pack with 2.71"! Mountain resorts had well over a foot of snow! I'll be posting the year end charts for Rain and Temperature later today and others as data becomes available.
Monday, December 28, 2020 - 8:44 PM - The tail end of the storm passed through in the past hour with another nice squall with similar amount as the opening squall, total now .61". Will post final totals tomorrow. Should be enough to resume the greening initiated by the early November storm. Moon out now.
Monday, December 28, 2020 - 5:07 PM - A very nice strong but brief squall went through here between 2:30 and 3 AM - early morning gauge reading: .30". One good flash following by thunder! We've had almost nothing since then, a reading a few minutes ago show .31" storm total. A contact in the L.A. reported heavy showers with thunder and lighting, well over an inch there. Storm totals via NWS as of 4:02 PM: Encinitas .18", San Marcos .26", Escondido .35", SD Airport .32", La Mesa .39". San Diego mountains generally had over 1 inch and snow peaks 8-12". There are more showers off the coast, hoping for more here - we really need it!
Friday, December 25, 2020 - 9:34 AM - An upper air trough passed through yesterday, with virga and scattered big drop rain showers. 03" here in Elfin Forest. The third strong Santa Ana in the past month blew through here the previous night. The first of the three one was the strongest, we didn't have power here for about 36 hours and the winds stripped leaves from trees and shrubs and knocked down several branches.
Monday, November 9, 2020 - 1:56 PM - I was premature in calling yesterday's .72" as the final read. I emptied the gage last evening, this morning there was .16" more! So the total here is .88". NWS figures as of 10:03 AM today: Encinitas .52", San Marcos Landfill .67", Escondido .77". Other readings: SD Airport .26", La Mesa .74". Lake Cuyamaca still the champion at 3.98". Big Bear Snow Summit: 18"! Next storm forecasted to pass north of here this weekend, small brush by possible.
Sunday, November 8, 2020 - 9:24 PM - Final rain gauge read here: .72", nothing since late afternoon. Been very windy, with temps around 56 feels frigid! NWS figures as of 5:03 PM: Encinitas .46", San Marcos Landfill .50", Escondido .69". Other readings: SD Airport .26", La Mesa .72" (same as us). Lake Cuyamaca still the champion at 3.51"!
Sunday, November 8, 2020 - 10:07 AM - By late yesterday afternoon another shower brought the total here to exactly .50" and this morning's read was exactly .60". Nothing in the last couple hours. More showers expected today and ending this evening although the air is a lot more stable than yesterday. Nearby totals at of 9:02 AM per the NWS: Encinitas .40", San Marcos Landfill .44" and Escondido .58". SD Airport just .14", La Mesa .62". Lake Cuyamaca leads the pack with a super impressive 2.7"! Snow has fallen in the mountains with Arrowbear leading at 10", Big Bear Village 5", the snow readings are as of 7PM yesterday evening. So... we are off to a great start for this year's rainy season and thankfully a lowered fire danger.
Saturday, November 7, 2020 - 3:44 PM - Another brief but vigorous shower / squall went through, increasing the storm total here from .35" to .45".
Saturday, November 7, 2020 - 7:52 AM - Wonderful rain! A couple brief rather heavy showers passed through this morning. Just checked the gauge, .34" already.
Monday October 26, 2020 - 8:32 AM - The third and last shower yesterday was very light, bringing the gauge to .07" for the storm total here in western Elfin Forest. The NWS totals for the nearby areas: Encinitas also .07", Escondido .05". Other locations: SD Airport .12", La Mesa doesn't list, zero? Top two spots: Palomar .86" and Lake Cuyamaca .65". This coming week will be dry with fairly strong Santa Ana to the north today and tomorrow.
Sunday, October 25, 2020 - 2:49 PM - Rain!!! A nice shower moved in from the west, the center moving just south of us, but close enough to "dump" .05" of rain, bringing the gauge to just over .06". Another shower band is approaching.
Sunday, October 25, 2020 - 10:58 AM - Rain!!! Well just over .01" from a light shower this morning. Still, the rainy season approaches. First rain in 17 weeks!
Sunday, September 6, 2020 - 9:52 PM - Today the heat wave set records all over the place. Here we reached 104 and stayed there for 2 or 3 hours. Yesterday San Diego failed to break the record of 97, and today did, hitting 100. The most impressive temperature record, in my opinion, was Escondido hitting 115, the highest temperature ever recorded there going back to 1893 and breaking the day's record by 11 degrees. The "Valley Fire" in south county passed 5,000 acres, the smoke has been visible for the last couple days. To the north, as distant plume of the El Dorado fire in San Bernardino county was also visible.
Also of note, the Arctic Sea Ice has retreated to its second lowest level since records began in 1979. I will update the graph after the data is in early next year.
Sunday, September 6, 2020 - 8:03 AM - Yesterday's high here in Elfin Forest was 103! This morning at 8 AM it is 88, yesterday at 8 AM it was 78. Whoa. Going to be another scorcher.
Saturday, September 5, 2020 - 10:39 AM - Heatwave! Record heat forecast for a wide area of Southern California. There will be just a little cooling along the coast. San Diego Airport record for this date 97, will be close there. 110 or higher predicted for inland valleys. Currently here in Elfin Forest 91.
Wednesday, September 2, 2020 - 10:13 AM - We closed the sale of our house in Bankers Hill! So I no longer have a rain gauge there. Finally back to one house and a simpler life. My main (and only) rain gauge location is in Elfin Forest from now on.
I will be adding an advertisement to these environmental pages for Edible San Diego, a weekly digital local foodie magazine published by my wife, Katie Stokes. The digital e-zine is usually published on Tuesday. The publication is also published quarterly as a print magazine. We need subscribers! And of course, advertisers.
Wednesday, July 1, 2020 - 10:23 AM - Final total for Monday's rain: .26". SD Airport .08", Encinitas .10", Escondido .11", La Mesa .15". I will be posting the annual rain chart update for the July-June season and monthly rain total later today.
Monday, June 29, 2020 - 8:13 AM - Rain! On Saturday another bout of fog and drizzle, another .02" no figures from NWS. Today "heavy" drizzle and bona-fide light rain. .22" in the gauge as of a few minutes ago!!! NWS has just posted updated figures. As of 8:01 which is nearly the exact time I took my reading: SD Airport .05", Encinitas .10", Escondido .11", La Mesa .00". NWS has Sylvan Meadows leading all areas with .20", but I vouch for .22" here on our little ridge in Elfin Forest!
Thursday, June 25, 2020 - 10:23 AM - Updates here have been delayed due to some remodeling and disconnected computer. We've had several days of morning fog and drizzle at Elfin Forest: Last Saturday .02", yesterday .02" and this morning a touch more than .01". No totals are present on the NWS site.
Saturday, June 6, 2020 - 9:19 PM - Had some early morning mist maybe very light rain again, .02" total. NWS rain totals as of 9:00 AM: SD Airport .06", Encinitas .00", Escondido .02", La Mesa .16"! Drier warmer weather is now in front of us.
Friday, June 5, 2020 - 8:46 PM - This morning the ground was quite wet from heavy marine layer drizzle or maybe very light rain. Checked our Elfin Forest gauge: .04"! NWS rain totals as of 8:45 AM: SD Airport .00", Encinitas .00", Escondido .01", La Mesa .00". Vista led the coastal totals with .07". May get something similar tonight.
Tuesday, May 19, 2020 - 9:51 AM - Light rain shower late last night, .03" in the Elfin Forest gauge. NWS posted totals as of 5:01 AM: SD Airport, Encinitas, Escondido, La Mesa all nothing .00". Inland mountains a whole lot more: Julian .47", Lake Cuyamaca .60"!
Wednesday, May 13, 2020 - 9:12 AM - Some showers last night, .05" in the Elfin Forest gauge! Not bad as there was nothing in the forecast a few day ago. NWS has now posted totals as of 5:01 AM: SD Airport .02", Encinitas .00", Escondido .02", La Mesa .00". Inland mountains had more, for example Julian .23".
Tuesday, May 12, 2020 - 7:43 PM - I forgot to post on May 9 (edit - corrected from May 10) had "heavy" drizzle in the morning, .04" in the rain gauge! None of the other locations I track here reported anything. About an hour ago, with low marine layer coming in, we had a sudden total unexpected shower with fairly large raindrops, but lasted just a couple minutes, about .005", officially a trace.
Wednesday, April 30, 2020 - 8:48 AM - Covid-19 Stay At Home day 43. Third foggy morning in a row with each morning thicker than the previous. .01" in the gauge from collective dew drop drippings, no rain here, nothing posted at NWS since April 18. We did have a rather warm spell and SD Airport tied record high readings three days running: April 24, 83 degrees tied 1995, April 25, 83 degrees tied 1992, April 26, 88 degrees tied 2004. SD did set new records for highest minimum: April 24, 63 degrees broke 1981 62, April 25, 63 degrees tied 1992, April 26, 64 degrees broke 1992 63.
Wednesday, April 22, 2020 - 9:23 AM - First warm spell of the season is upon us. More rain in April is unlikely. Added a bit more commentary in the analysis section of the Methane Levels page. Meanwhile my normal period for the annual observing and updating of my Time Lapse Lichen project has come and gone, thanks to COVID-19. Maybe in May.
Saturday, April 18, 2020 - 11:51 AM - Methane Levels page updated.
Saturday, April 18, 2020 - 9:36 AM - Light showers overnight, .08" as of about 8 AM in our Elfin Forest rain gauge. NWS storm totals as of 7AM: SD Airport .03", Encinitas .03", Escondido .01", La Mesa .03". Carlsbad Airport had .14", so our reading is not a fluke. Will now start working on the Methane charts.
Friday, April 17, 2020 - 9:17 PM - The 2019 data for my Methane Levels page is in. I'll update the page tomorrow. I have processed the 2019 data and am saddened to say that a new record yearly average was set, and the increase was the biggest in 28 years.
Monday, April 13, 2020 - 6:27 PM - NWS posted "storm" totals as of 4:16 PM. SD Airport .06" (an increase of .03" from my post), Encinitas .10" (no change), Escondido .05" (no change), La Mesa .07" (an increase of .01"). I received a reading from my Bankers Hill gauge: .33", some of that may have been residual from last Friday. Pretty gloomy all day - looking forward to some sunny days!
Monday, April 13, 2020 - 9:30 AM - Corrected yesterday's time stamp to AM instead of PM. Around 10:30 PM last night we had a short moderate shower then around 2-3 AM a heavy enough shower to wake me up. Local radar was inexplicably blank in both cases, maybe down? A reading of my Elfin Forest gauge this morning: .14"! NWS has not posted totals since Saturday. Looking at the CA / NV river forecast map https://www.cnrfc.noaa.gov/precipMaps.php?group=san&hour=24&synoptic=0 shows 24 hour most recent precipitation: SD Airport .03", Encinitas .10", Escondido .05", La Mesa .06". Interestingly Point Loma has .21".
Sunday, April 12, 2020 - 10:55 AM - Cloudy, thick marine layer, a few tiny drops, a trace of a trace. SD Airport April month to date, 3.59" already the third wettest April going back to 1852. There was 3.71" in 1988 and 5.37" in 1926. Brings the winter total at the airport to 13.41", the wettest for a whole season since 2004.
Friday, April 10, 2020 - 10:55 PM - No further rain here in Elfin Forest, storm total set at 6.68". NWS storm totals released at 9:02 PM: SD Airport 3.50" (no change), Encinitas 7.40" (an increase of .10"), Escondido 5.30" (no change), La Mesa 4.80" (no change). The NWS also issued 24 hours totals as of 10:40 PM: SD Airport 2.01", Encinitas 4.61" the highest of all stations covered by the local NWS office, Escondido 2.98", La Mesa 2.25". Here we had over 3" in this 24 hour period.
For all those who contacted me at SD John Weather Notes recently, thank you.
Friday, April 10, 2020 - 7:21 PM - OK not "late evening". The rains have finally stopped, the "eye" of the storm is visible offshore with far off clouds moving south and closer ones moving north! Another .50" here, storm total 6.68". NWS storm totals as of 5:47 PM: SD Airport 3.50" (a decrease (??? just reading what is posted, double checked) of .03"), Encinitas 7.30" (an increase of 1.62" !! and taking the lead), Escondido 5.30" (an increase of .35"), La Mesa 4.80" (an increase of 37"). Clearly that band near the coast must have clobbered some records!
I also received an update from our Bankers Hill gauge: 3.4" since the Tuesday morning @ 10:30. Figure a storm total in the low to mid 4 inch range.
Friday, April 10, 2020 - 2:40 PM - NWS just updated their storm totals (previously were as of 10 PM). As of 2:15 PM: SD Airport 3:53" (an increase of just .27"), Encinitas 5.68" (an increase of .60"), Escondido 4.95" (an increase of .47"), La Mesa 4.43" (an increase of .36"). So here at our Elfin Forest location we are getting slammed by the band which is moving over us along the spine of the band instead of a quick passover. My next update will be late this evening.
Friday, April 10, 2020 - 2:28 PM
Red dot rough location of my Elfin Forest rain gauge - storm moving slowly east / southeast
"If it keeps on raining, levee's going to break"
Friday, April 10, 2020 - 2 PM - Incredible but true... since the last reading we have just over .75" in the gauge! So, this historic storm has a local total of 6.18". Another band formed after what I thought was the "last one" and intensified. The center of the circulation is right off the coast. Maybe we'll get some more wrap-around? No NWS storm total update.
Friday, April 10, 2020 - 10:40 AM - Just took a new reading: .56" more in less than two hours. So that's 2.19" since yesterday evening's post and about 2.5" in the last 24 hours (more than 2" in SD within 24 hours is very unusual). Storm total now 5.43"!! The NWS has updated their storm totals as of 10 AM: SD Airport 3:26" (an increase of .73"), Encinitas 5.08" (an increase of 1.48"), Escondido 4.46" (an increase of 1.36"), La Mesa 4.07" (an increase of 1.07"). Just one more small blob of rain to go here after the current wave which is lightening up now.
Friday, April 10, 2020 - 8:45 AM - Wow, Wow, WOW! Just took at reading of my Elfin Forest gauge. 1.63" since yesterday's read! Been raining hard and still coming down. Looks like one or two more bands will pass through and then we will be done. Rain storm (going back to last Sunday night) total here 4.87"!!! Saw a picture of Escondido Creek flooding Harmony Grove Road, there must be flooding elsewhere in the county, for sure. Quite epic for San Diego, particularly in April as the normal for the whole month is something like 0.77" at the airport. For the season we are well above normal (Nov, Dec, Mar, Apr super wet, Jan, Feb dry), the airport is probably about 3" above normal now for the season. NWS storm totals are a stale, latest post is as of 4:02 AM, we've had a lot in the 4+ hour since then. Anyway: SD Airport 2.60" (an increase of 1.04"), Encinitas 3.60" (an increase of .77"), Escondido 3.10" (an increase of .67"), La Mesa 3.00" (an increase of .45").
Thursday, April 9, 2020 - 9:16 PM - It took a LONG time for that large slow moving counter clockwise blob of rain to reach us... and now some stronger bands are approaching. My Elfin Forest gauge has added .31" since this morning's post, the reading taken just moments ago. Storm total now 3.24"! NWS storm totals as of 8:47 PM: SD Airport 1.56" (an increase of .09"), Encinitas 2.83" (an increase of .40"), Escondido 2.43" (an increase of .34"), La Mesa 2.55" (an increase of .16"). There are some very impressive figures in the San Bernardino mountains, the leader is Lytle Creek RAWS with 9.02".
Thursday, April 9, 2020 - 9:07 AM - .19" here since the last post, bringing storm total to 2.91". A very large solid surge of rain appears to be approaching from the NW, wrap around moisture from the closed low. Going to get weeding in before the rain approaches. NWS storm totals as of 5:02 AM: SD Airport 1.47"' (an increase of .09"), Encinitas 2.43" (an increase of .38"), Escondido 2.09" (an increase of .05"), La Mesa 2.39" (an increase of .04"). Next post not until late this evening.
Wednesday, April 8, 2020 - 5:13 PM - Just a few sprinkles here, Elfin Forest total now 2.72"; current activity has moved well to the east. NWS totals as of 3:47 PM: SD Airport 1.38" (an increase of .01"), Encinitas 2.05"(an increase of .08"), Escondido 2.04" (and increase of .12"), La Mesa 2.35" (no change).
RAWS stands for Remote Automated Weather Station. They are operated by the Forest Service and the Bureau of Land Management.
Wednesday, April 8, 2020 - 11:34 AM - End of current showers, .37" additional, Elfin Forest gauge total now 2.70".
Wednesday, April 8, 2020 - 10:52 AM - Heavy rain and BB sized hail!
Wednesday, April 8, 2020 - 9:14 AM - Woke up around 2AM, heavy shower was in progress. Elfin Forest reading as of about 8:30 AM, .19" additional, bringing storm total to 2.33". NWS totals as of 7:02 AM: SD Airport 1.37" (an increase of .21"), Encinitas 1.97" (an increase of .07"), Escondido 1.92" (an increase .32"), La Mesa 2.35" (an increase of .43").
Also of note was that yesterday afternoon it was very windy here. I'm now thinking I want to set up a full scale weather station here. Stay tuned although won't happen right away.
This morning's forecast as of 8:28 AM calls for "around 1 inch along the coast" for the remainder of this stormy period.
Tuesday, April 7, 2020 - 9:17 PM - Received a report from the Bankers Hill gauge 1.24" - this reading was taken around 10:30 AM. However there may have been .20-.30" in there from before. As for Elfin Forest, we had some light rain showers, coming in at .13" by late afternoon, bringing the storm total to 2.14". NWS storm total figures as of 7PM: SD Airport 1.16" (an increase of .37"), Encinitas 1.90" (an increase of .41"), Escondido 1.60" (an increase .36"), La Mesa 1.92" (an increase of .20") so yesterday Elfin Forest was the champ, today less than the others. San Bernardino station Lytle Creek RAWS is the overall champ with 6.54". Anyone know what "RAWS" stands for?
Yesterday night's forecast called for 1.5-2" additional rain along the coast; that figure is now 0.6-1.25" along the coast.
Tuesday, April 7, 2020 - 9:33 AM - The extended segment of rain ended late last night. An early morning read of my Elfin Forest gauge showed 2.01"! Having light drizzle now. I'm attempting to get a read on my Bankers Hill gauge. NWS storm totals as of 8:01 AM: SD Airport .79", Encinitas 1.49", Escondido 1.24", La Mesa 1.72"(!). The NWS SD discussion is still calling for 1.5-2" of additional rain along the coast before this is all over late Thursday!
Occasionally I receive a request for daily rain data. I don't maintain daily records as they are available via the NWS. Go to https://w2.weather.gov/climate/index.php?wfo=sgx and you will see something like this which is easy to navigate:
Monday, April 6, 2020 - 10:28 PM - Heavy rain! Latest Elfin Forest reading now 1.68" for the storm. Radar indicating an end for this spell within a couple hours. NWS Totals as of 9:10 PM: SD Airport .53", Encinitas 1.18", Escondido .67", La Mesa still missing. La Mesa 24 hours ending 10 PM just .18" (https://www.cnrfc.noaa.gov/images/countyPrecipMaps/sandiego_24HRprecip.png) This map as of 10 PM shows SD Airport .61", Encinitas 1.42", Escondido .79. My Elfin Forest gauge is rocking! Only Palomar Observatory 2.35" and Birch Hill 2.27" have more.
Monday, April 6, 2020 - 8:41 PM - Rain! Took a while to get going, didn't start in earnest not including the 2 AM heavy show until around mid afternoon. By ~6:30 PM .64" and just now 1.02" at mu Elfin Forest gauge with a good steady rain! The main rain has been north and west of here with meager amounts in SE SD county. The latest NWS storm total figures are as of 7:08 PM, so are a bit stale compared to my reading: SD Airport .35", Encinitas .69", Escondido .38", La Mesa is not shown, but on the 8PM SD County map is showing just .11". Up north in the San Bernardino area 3+ and 4+ inch readings are common.
Monday, April 6, 2020 - 9:39 AM - Covid-19 Stay At Home day 19. Woke up @2AM thanks to a rather heavy shower. Checked the Elfin Forest gauge a few minutes ago: .28", nice! I don't think there has been any rain since then although a drizzle has just started and radar is showing an impressive band approaching crossing Irvine. NWS storm totals as of 8:47 AM: SD Airport .22", Encinitas .17", Escondido .14", La Mesa a measly .03".
Sunday, April 5, 2020 - 8:22 PM - The forecast for heavy rains is still very much on track as of the 1:11 PM NWS forecast: Coast/Valley: 1.50-2.75 inches. Urban and small stream flooding will be a concern for all of these areas.
Current radar shows the main bands west of L.A. now reaching the Channel Islands.
Several more people have contacted me saying they occasionally check in here. Thank you. Will keep this going!
Friday, April 3, 2020 - 10:27 PM - The NWS weather discussion for San Diego is full of rain talk! Normal rain for the month of April in San Diego is about 0.7". Here is the latest as of 8:26 PM: Total precipitation next week should range from 1.5 to 2.5 inches coast and valleys. 2.5 to 3.5 inches in the mountains but amounts up to 6 inches in the San Gabriel and San Bernardino County mountains.
The rain is to come in two swatches: Monday afternoon and Wednesday morning. I'll be monitoring my Elfin Forest gauge and I'll see what I can do to have someone monitor the San Diego (Bankers Hill) gauge.
Friday, March 27, 2020 - 8:32 AM - Hits or miss showers passed through last night, mostly miss here. Received a report of hail in Bankers Hill. Just .02" in my Elfin Forest gauge. NWS figures as of 4
Thursday, March 26, 2020 - 10:45 AM - Thank you Lynn, Jessica, Valerie and Neil for writing! I'll keep this going! Last night at Elfin Forest we had a couple strong but fairly short showers go through. This morning's gauge reading: .25".... so we break 5" for the month at 5.01! Everything is so.... green. Spent the last three days of this pandemic-stay-at-home weeding as I'm trying to eliminate the thistle infestation of open areas before they go to seed. Back to weather.... NWS figures as of 7:01 AM: SD Airport .04" again in the dog house, Encinitas .08", Escondido .39" (so once again we come in the middle of Enci & Esco), La Mesa .10".
More showers on the way tonight.
Meanwhile I still haven't received Methane Levels... time to starting bugging for them.
Monday, March 23, 2020 - 2:13 PM - I was able to obtain a Bankers Hill gauge reading: .31", that would be since about noon on March 18. SD Airport received .22" since then so the reading is in the same ballpark.
Monday, March 23, 2020 - 10:23 AM - Rain last night and early morning, exactly .50" in my Elfin Forest rain gauge, bringing the March total to 4.76"! NWS totals through 8AM: SD Airport .09", Encinitas .48", Escondido .53", La Mesa .23". Again the Encinitas / Elfin Forest / Escondido band did better than southern SD county. Carlsbad, Del Mar and Oceanside all had more than 1/2".
Saturday, March 21, 2020 - 8:45 PM - Yesterday morning, March 20, we had .12" at my Elfin Forest gauge. Brings the March total to 4.26". NWS totals: SD Airport .13", Encinitas .32", Escondido .20", La Mesa .36".
Thursday, March 19, 2020 - 9:41 AM - Mid afternoon yesterday my Elfin Forest gauge was at .70". I'm guessing about .40" fell in the March 16-17 overnight and .30" yesterday through mid afternoon. We had very heavy rain showers last night (at least two direct hits from small cells) and although SD Airport showed nothing overnight we had an additional .73"!! So far this month my Elfin Forest gauge has totaled 4.14"!! NWS storm totals for overnight at of 8:30 AM: SD Airport .00" (zero!), Encinitas .23", Escondido .48", La Mesa. 14". The leader is "Goose Valley Raw" at .71". I vouch for my reading .73".
As mentioned due to the Covid-19 pandemic, readings at Bankers Hill have been suspended although the gauge is still setup, will read it eventually.
Wednesday, March 18, 2020 - 11:32 AM - Showers this morning. My gauges: Bankers Hill .23", Elfin Forest (not available, I'll have a total including yesterday later), NWS gauges as of 10AM: SD Airport .16", Encinitas .13", Elfin Forest (not reported - due to the erratic reporting from this NWS gauge I'm going to discontinue attempting to post it, of course I'll continue to report my own Elfin Forest gauge), Escondido .10", La Mesa .12". The leader is Tierra Del Sol with .32".
Due to the Covid-19 pandemic I'm going to be at the Elfin Forest location for at least two weeks. I won't be reporting the Bankers Hill gauge during this time. Will post total when I return.
Tuesday, March 17, 2020 - 5:55 PM - Yesterday evening, in Bankers Hill around 10:30 a nice band of rain arrived, with showers lasting a few hours. My gauges: Bankers Hill .36", Elfin Forest (not available). NWS gauges: SD Airport .26", Encinitas .16", Elfin Forest (not reported), Escondido .46", La Mesa .41". Additional rain is predicted for Wednesday into Thursday (1/3" to 2/3") and again Sunday into Monday, no numbers posted.
Still waiting for Methane Levels data.
Monday, March 16, 2020 - 4:01 PM - There was some additional showers last Friday and into Saturday. I think (misplaced notes) the final total for Bankers Hill was .66", and 1.79" in Elfin Forest.
NWS published 5 day totals as of 9:02 Saturday March 14. My gauges for the 5 days: Bankers Hill .97", Elfin Forest 2.80", NWS: SD Airport 1.19", Encinitas 2.76", Elfin Forest (not reported), Escondido 3.49"(!), La Mesa 2.25"
Friday, March 13, 2020 - 9:36 AM - Around 8:15 AM a very strong but brief squall with heavy rain pass through Bankers Hill, tossing around patio chairs and knocking down a children's play structure next door. Just checked the gauge here, .26" additional bringing the two day (March 12-13) storm total to Bankers Hill to .57". Also just received a reading from my Elfin Forest gauge, .25" additional bringing the storm total to 1.65". Two day NWS figures as of 9:01 AM: SD Airport .43", Encinitas 1.88", Elfin Forest 1.32", Escondido 2.07", La Mesa 1.19". March has turned into a very, very good month, countering the short falls in January and February, and there is more to come!
Thursday, March 12, 2020 - 9:54 PM - Lots of rain!!! Totals for the storm which ended March 11 morning: My gauges: Bankers Hill .57", Elfin Forest a fat 1.01". NWS figures: SD Airport .56", Encinitas .71". Elfin Forest (not reported), Escondido 1.21", La Mesa .63".
For today's storm (March 12) through 4PM - My gauges: Bankers Hill just .31", Elfin Forest a very fat 1.41" had some good downpours, NWS figures SD Airport just .26", Encinitas 1.47", Elfin Forest .84", Escondido the leader at 1.64", La Mesa 1.10". So parts of southwest SD county received much less than the Encinitas/Escondido belt. Some light rain is falling now in Bankers Hill will update tomorrow.
Tuesday, March 10, 2020 - 10:32 AM - Nice rain last night, no heavy rain so far today. My Bankers Hill gauge: .36". Will have my Elfin Forest reading later this week: NWS figures as of 9:01AM: SD Airport .31", Encinitas .58", Elfin Forest .46", Escondido .71", La Mesa .32".
Monday, March 9, 2020 - 5:07 PM - Over this past weekend Saturday and particularly yesterday morning there were light showers. Storm totals: Bankers Hill. 12", Elfin Forest .02", SD Airport .01", Encinitas .21", NWS Elfin Forest .02", Escondido .02", La Mesa .09". "Heavy Rain" is predicted for tomorrow! The figures have been coming down in the past 24 hours, but the forecast still calls for an inch along the coast and up to 3" in the mountains. Much needed.
Monday, March 2, 2020 - 7:03 PM - Disappointingly light showers passed through Bankers Hill last night / early this morning. Storm totals: Bankers Hill .03", Elfin Forest .02, SD Airport .01", Encinitas .00", NWS Elfin Forest .06", Escondido .14", La Mesa .14". I heard a first hand report from San Marcos that there was some small hail this afternoon - evidently while skies were mostly clear in the county this afternoon there were a few pockets of high instability. There were much higher storm totals in the San Bernardino Mountains area, City Creek Ranger Station took the prize with 1.22".
Sunday, February 23, 2020 - 8:33 PM - First of all, our place up north is not in Olivenhain, rather just over the border in extreme western Elfin Forest. So when I when I mention my northern gauge I'll say "Elfin Forest" and for the NWS Elfin Forest reading I'll say "NWS Elfin Forest". Yesterday up north we had a direct hit by a thunderstorm with lighting, thunder and small hail! Storm totals: Bankers Hill .13", Elfin Forest a fat .54", SD Airport .11", Encinitas .62", NWS Elfin Forest .38", Escondido .38", La Mesa .18".
Still waiting for Methane Levels data.
Tuesday, February 10, 2020 - 3:44 PM - We had some light rain yesterday afternoon and several nice periods of light to almost moderate rain today. Rather sunny now. Storm totals for Feb 9-10: Bankers Hill .34", SD Airport .27", Encinitas .31", Elfin Forest .34", Escondido .48", La Mesa .41". Of note was a band of rain which move north just off the coast, Point Loma received 1.36" and Mission Beach .66" while just inland Sea World received just .13". Meanwhile, still waiting for Methane Levels data. When I get the data and post it I'll then post all of the graphs as a group on Instagram.
Monday, February 3, 2020 - 12:20 PM - Just a trace of rain in Olivenhain, super light drizzle yesterday evening. Bankers Hill 0", SD Airport 0", Encinitas 0", Elfin Forest 0", Escondido wins with a massive .01", La Mesa 0". Meanwhile the San Diego Sea Levels data for the year is now in, will update today, shortly.
Monday, January 27, 2020 - 8:36 PM - The figure for Olivenhain for the January 21 event was .35". Meanwhile with no more rain predicted for January, San Diego January will come in quite a bit below normal. Will post towards the end of the month.
Tuesday, January 21, 2020 - 2:16 PM - I have updated the annual chart for Nitrous Oxide Levels for 2019 with added commentary. I'm still waiting for end of year figures for Sea Levels and Methane.
Tuesday, January 21, 2020 - 1:18 PM - Follow-up bands of rain came through last night and early morning, making it to the ground dumping far more rain than expected! Totals: My gauge at Bankers Hill .31", SD Airport .25", Encinitas .26",Elfin Forest .25", Escondido .37", La Mesa .32".

Friday, January 17, 2020 - 8:234 AM - Frontal rain passage over, had a few nice clumps of rain, .20" total here in Bankers Hill, better than the "less than .10" predicted.
Monday, January 13, 2020 - 12:23 PM - Per request I'm now making my San Diego temperature history file available as downloadable text. For more details see San Diego Temperature.
Sunday, January 12, 2020 - 8:17 PM - Rain totals for last Thursday, January 9: Bankers Hill .12", Olivenhain .03", SD Airport .05", Encinitas .00", Elfin Forest .01", Escondido .00", La Mesa .00".

Wednesday, January 1, 2020 - 3:27 PM - I have updated the annual charts for San Diego Temperature and Arctic Sea Ice for 2019 with added commentary. I'm still waiting for end of year figures for Sea Levels, Carbon Dioxide, Methane and Nitrous Oxide.
The time lapse I posted yesterday has a super interesting sequence for a few seconds around the 14 second mark. The stationary lenticular cloud formed a "curly top" as it was being sheared by winds above the cloud.
Curly top cloud, December 31, 2019
Tuesday, December 31, 2019 - 8:44 PM - Just a trace in Olivenhain today, and nothing in San Diego nor the other locations I track. I've updated the annual and decade rain fall charts at San Diego Rain. Total for the year at SD Airport came in at 15.28", the most in nine years. My annual rain commentary is on that page. Today there were some super cool lenticular clouds and I posted a time lapse on Instagram at my https://www.instagram.com/johnstokesiii/ account.
Monday, December 30, 2019 - 11:48 AM - The third storm of the latest trilogy remains offshore and the situation is looking like there will be nothing in my gauges for the remainder of the year. Tomorrow is almost certain to be sunny. Will update my calendar year rain chart tomorrow or Wednesday at San Diego Rain. As the decade is done, I'll make a final update to the 2010's decade bar too and add commentary on that page. Will also be updating San Diego Temperature and Arctic Sea Ice on Wednesday or Thursday
Sunday, December 29, 2019 - 8:00 PM - Olivenhain total for the period December 23-26 was 2.54", gauge checked on December 27nd.
Thursday, December 26, 2019 - 7:07 PM - An wonderfully intense rainstorm starting very late last night and ending around daybreak this morning dumped 1.29" of rain here! In the SD county mountains there was heavy snow with I-8 being shutdown. There have been showers since this morning along the coast and more snow inland, but nothing here. NWS 24 hour storm totals as of 4:01 PM: SD Airport 1.28" (almost exactly matching my total), Encinitas 1.32", Elfin Forest 1.44", Escondido 1.63" (leading the inland valley locations), La Mesa 1.12". A storm for next Monday, December 30 is in the forecast with increasing chances, but details are still quite fuzzy. This year is already the second wettest year in the last 21 years!
Wednesday, December 25, 2019 - 12:57 PM - Light showers last night from the spotty "in-between-storms" system. Bankers Hill gauge: 04", NWS totals as of 6:45 AM: SD Airport .01", Encinitas .10", Elfin Forest .31", Escondido .29:, La Mesa .12". Again, big storm still on track for late tonight and mainly tomorrow, should be in excess of one inch here.
Tuesday, December 24, 2019 - 1:59 PM - Final totals for the Dec 23 (and a bit into Dec 24, 2019) storm: My Bankers Hill gauge: 1.31", NWS totals as of 8:31 AM (no rain here since then): SD Airport 1.34", Encinitas 1.16", Elfin Forest (not shown, sigh), Escondido 1.31", La Mesa .86". Big storm still on track for late Wednesday and mainly Thursday.
Monday, December 23, 2019 - 7:50 AM / 9:08 PM - Rain, again! A rather heavy band moved through here (San Diego) in the past couple hours/
Thursday, December 12, 2019 - 7:30 PM - Olivenhain total was .31", gauge checked on December 10th.
Monday, December 9, 2019 - 11:05 AM - Final total .27". NWS storm totals as of 5:02 AM today - SD Airport .21", Encinitas .19", Escondido .30", La Mesa .29".
I fixed the video link so it starts at the beginning instead of 63 seconds into the video. The video is at https://www.youtube.com/watch?v=pVMQ4ZMs0ug
Sunday, December 8, 2019 - 3:28 PM - Last month on November 17, in Olivenhain, the sunset was the most unusual I ever saw - I was, with others, watching the sunset when in what would normally be the final few seconds, the sun seemly "stood still and took forever" to actually set. I was recording the sunset and I captured the whole period. The corrected video link is at https://www.youtube.com/watch?v=pVMQ4ZMs0ug
Sunday, December 8, 2019 - 1:56 PM
Saturday, December 7, 2019 - 10:23 AM / 3:00 PM
Friday, December 6, 2019 - 9:29 AM - Final storm totals for the December 4-5 storm: Bankers Hill 1.38", Olivenhain 1.18", SD Airport 1.19", Encinitas .89", Escondido 1.55", La Mesa 1.33". A big storm is moving well to the north of us this weekend, light rain is predicted locally.
Wednesday, December 4, 2019 - 7:44 AM / 9:04 AM -
Sunday, December 1, 2019 - 6:41 PM - I've been away from my computer that has the software for updating this website, but I managed to monitor both gauges in the meantime. What a storm! Up in Olivenhain last Wednesday we received .40" as of 10 PM. The last reading I took on Thursday was at 2.02" storm total - I heard one distant roll of thunder late in the afternoon. Friday morning at 7:45 AM the storm total was at 2.40" and by the end of Friday a few scattered showers brought the final storm total read at 2.53". Meanwhile at Bankers Hill, Katie (my wife) took the first read on Friday morning with storm total of 1.87", and when I returned another .10" had fallen afterwards bringing the final storm total to 1.97".
So.... Bankers Hill 1.97", Olivenhain 2.53", SD Airport 1.95" (just about matching Bankers Hill), Encinitas 2.69", Escondido 2.55" and La Mesa 2.14". November ended the streak of dry months in excellent fashion, well above normal. Looks like .5-1" coming up this Wednesday, gauges ready!
Monday, November 25, 2019 - 8:04 PM - The November 19-21 rainstorm dropped exactly 1.50" in my Olivenhain gauge. NWS has been advertising a huge storm for the second half of this week. The projected rain figures have been in a slow decline, but still are at a fat 1.5 to 2" for the coast / valleys (down from original figure of something like 3-4"). Gauges are ready.
Thursday, November 21, 2019 - 4:05 PM - Rain ended early morning after some strong showers. Final storm total here at Bankers Hill .86", a great start to the rainy season. NWS storm totals for the other areas I track here as of 10:47 AM: SD Airport .77", Encinitas .88", Escondido 2.40", La Mesa 1.28". Henshaw Dam led the county with 4.69". My guess for my Olivenhain gauge is somewhere between 1.25 and 1.5". I'll get a reading tomorrow and post it by the end of the weekend.
Wednesday, November 20, 2019 - 8:24 PM - Rain continued today but with wide variations, not the monolithic soaking rain I was hoping for with coastal areas coming in well under forecast. As of 8:15 PM our Bankers Hill gauge showed .46", .35" since yesterday evening's read. I won't get to the Olivenhain gauge for a few days. The NWS has been much better this year in updating their "Storm Totals" page, with frequent updates, I thank them for that. As of 7:32 PM, storm totals are SD Airport .42", Encinitas .49", Escondido an even fatter 2.09"and La Mesa .84". Valley Center continues to lead, now with a super impressive 4.31".
Tuesday, November 19, 2019 - 7:43 PM - Rain! As of about 6 PM our Olivenhain gauge picked up .62" way more than I was expecting from the southern storm (I was expecting zero!) - a band wound around the center bringing plenty! In our Bankers Hill gauge, as about about 7:30 PM, only .11". The NWS storm totals as of 6:35 PM have SD Airport .10, Encinitas .10 (shows the narrowness of the band), Escondido a fat 1.06" and La Mesa .25". The leader is Valley Center with 2.17". The storm from the northwest is still to come!
Monday, November 18, 2019 - 2:44 PM - The NWS has been predicting the first winter storm of the season during this past week and the time is quickly approaching. Southern San Diego county will first get brushed with the remnants of tropical storm Raymond on Tuesday, then a normal frontal system will move through on Wednesday. Yesterday the projected coastal amounts increased to between 1 and 1 1/4" today downgraded to between 1/2 to 1". Hopes remain high. Meanwhile I purchase a gauge for Olivenhain like the one in Bankers Hill and set it up after taking this picture:
Monday, September 30, 2019 - 3:15 PM - The final Olivenhain rainfall measurement for September 28-29 periods was about 5/16" of an inch (.31"). Today I ordered a new Stratus Precision Rain Gauge for my Olivenhain location, the same as I have here in Bankers Hill. This will replace my vastly inferior gauge currently in Olivenhain.
Saturday, September 28, 2019 - 9:26 AM - Rain last night! Unfortunately I didn't make sure the gauge was empty late yesterday and I think water may have been in there from some garden watering activity. There was .28" this morning, but looking at some buckets I'd say the total was around 1/10 inch which would be consistent with the SD airport's .10" as of 8:15 AM this morning. So I go on record as "Missing". I'll have an Olivenhain reading later. Encinitas .05", Escondido .04", La Mesa .15".
Friday, September 27, 2019 - 6:42 PM - Some tropical air generated showers to the east a couple days ago - nothing here in Bankers Hill or Olivenhain. Deserts and mountains received nice rain, for example Mt. Laguna .71 over Sept 25-26. Today some drizzle moved into the Olivenhain area from the northwest and intensified to light rain, we received about .05" before I left around 10 AM - very local as I-5 was dry. Nothing in Bankers Hill. SD Airport is showing just .01" this month so far.
Wednesday, September 4, 2019 - 5:28 PM - Thunderstorm! A strong thunderstorm formed below the southern boundary of San Diego County along the mountain ridge and moved northward while expanding in size. Rain spread westward as the storm moved north, and into our area in Banker's Hill. The rain started out as scatter big raindrops then a nice downpour for 10 minutes or so shortly after 3 PM. A lot of thunder! Final total .14".
Monday, July 1, 2019 -10:08 PM - The 2018-2019 July-June rain season ended up with12.84" at the airport. Nicely above normal. Chart updated at San Diego Rain
On June 29 at sunset we had one of the most spectacular sunsets ever with amazing colors thanks to the dissipating upper clouds from the first eastern Pacific tropical storm of the season, plus an upper atmosphere rainbow without any ground rain. The rainbow was visible over a wide area of San Diego country. I captured, in my opinion, one of the best sunset pictures ever!
Friday, June 21, 2019 - 8:57 AM - Summer solstice! Had drizzle last night, a tad over .04" in the rain gauge! The NWS posted figures as of 5AM. Here .04", SD Airport .01", Encinitas .08", Escondido nothing, La Mesa .01".
Monday, May 27, 2019 - 9:52 PM - Spent the weekend in Olivenhain. Had about .12" of rain there on Sunday. When I returned there was .15" in my Banker's Hill rain gauge. Don't know the distribution of precip over time. I see the airport had two periods of rain, one on Sunday morning w/ .03" and .05" later in the day. Two day totals: Here .15", SD Airport .08", Encinitas .06", Escondido .13", La Mesa .07". Mountain areas had a lot more, particularly in the San Bernardino area.
Wednesday, May 22, 2019 - 4:08 PM - Another brief but heavy shower went through late yesterday afternoon dropping .06", and this afternoon a couple squalls have dropped .09". Yesterday's SD airport figures show .04" and today, matches mine as .09". Looks to be clearing out for now. Yesterday's NWS log shows SD Airport .04", Encinitas .00", Escondido .00", La Mesa .00", so the showers were super local. Figures to include this afternoon's rain haven't been posted.
My Bankers Hill total so far this month is now 1.04"
Monday, May 20, 2019 - 12:27 PM - A brief but heavy downpour this morning and a couple light showers brought another .12" here. Surprisingly the airport just a couple miles away received just .01" this morning. My two day total is .42". Two day totals as of 12:01 PM today: SD Airport .18" (.02" more since yesterday's 4:30PM total), Encinitas .26" ( .01" more), Escondido .77" (.38" more continuing to lead the pack), La Mesa .60 (.31" more). The forecast is for more of the same mid week and next weekend.
Sunday, May 19, 2019 - 5:34 PM - The cooler than normal weather continues with a lot more rain than normal! Today in another frontal pattern we received exactly .30" here in Bankers Hill. The sun is now out. NWS storm totals are now out as of 4:30 PM. Here .30", SD Airport .16", Encinitas .25", Escondido .39", La Mesa .29". The NWS forecast nailed this one. Last Thursday's rain dropped about .12" in Olivenhain.
My Bankers Hill total so far this month is now .77"
Friday, May 17, 2019 - 8:11 AM - Yesterday received .05" of frontal rain in the Bankers Hill rain gauge, less than hoped. Totals: Here .05", SD Airport a paltry .02", Encinitas .13", Escondido .20", La Mesa .14". More fell in the mountains.
Monday, May 13, 2019 - 9:57 PM - Final totals for the three day period ending May 11: Here (Bankers Hill) .38", SD Airport .36", Encinitas .17", Escondido .21", La Mesa .15". My Olivenhain gauge had about .10".
Saturday, May 11, 2019 - 2:27 PM - Had some nice rain this morning, moving in from the east as low pressure moved south of here. Picked up .18" more, bringing the 3 day today to .38" and the month of May well above normal (.42" so far versus a whole month normal of about .27"), making up a bit for a dry April. Looking at the hourly SD Airport figures, they received .19" today which should bring their 3 day total to .36". Will check my Olivenhain gauge tomorrow.
Friday, May 10, 2019 - 12:45 PM - Yesterday, May 9 we had .09" here at Bankers Hill and so far today .11", the gauge has just over .20" since I last emptied it.
Monday, May 6, 2019 - 9:10 PM - Had a few scattered showers this morning; there were reports of brief but heavy showers in other places particularly Del Mar and Solana Beach. Storm totals: Here (Bankers Hill) .04", SD Airport .04", Encinitas .05", Escondido .08", La Mesa nothing. Mission Beach took home the prize with .32".
Tuesday, April 30, 2019 - 6:13 PM - Lots of heavy drizzle and a few light showers this morning. .11" additional water, bringing the two day total to .14". Two day totals: Here .14", SD Airport .09", Encinitas .31", Escondido .16", La Mesa .10". May receive some more of the same tonight going into tomorrow morning.
Monday, April 29, 2019 - 9:53 PM - Had a few light showers today, first rain in more than 3 weeks. Totals: Here (Bankers Hill) .03", SD Airport .01", Encinitas .16", Escondido .12", La Mesa .04". Could get a few more sprinkles and / or drizzle tonight.
Saturday, April 6, 2019 - 9:45 AM - Yesterday morning a light rain band passed through dropping .07". Drizzle later in the day brought the total to .09". Cleared out the gauge yesterday evening. Early this morning another period of light rain, dropping .05". The current forecast is for dry weather up to next Friday.
Two day totals as of 5:01 AM: Here (Bankers Hill) .14", SD Airport .07", Encinitas .11", Escondido .11", La Mesa .04".
Thursday, April 4, 2019 - 8:07 PM - A few patches of rain today in SD Country, nothing here. Looking like there will be some measurable rain tonight.
Wednesday, April 3, 2019 - 5:49 PM - Last night .02" fell in my Bankers Hill gauge. North county had more, mostly in the .05-.15" range. Storm totals: here .02", SD Airport nothing, Encinitas .05, Escondido .05", La Mesa .02".
Monday, March 25, 2019 - 9:36 PM - Last Saturday I went to check the Olivenhain rain gauge to see what was there from the March 20 and March 21 squalls. Unfortunately I found the gauge had been crushed to smithereens by a bulldozer on the way to a spot for landscape terracing! I've since set up a new gauge in a safer location. Meanwhile little if any rain is expected for the rest of March. The Banker's hill total since late November is 14.95"; remains to be seen if the we get any more good storms now that this season is winding down. The airport's total since late November is 11.04".
Thursday, March 21, 2019 - 8:22 PM - Our place ended up being in almost the perfect location for good rainfall. Today's showers netted .34". There was a thin longitudinal band of showers moving from west to east which soaked a narrow strip of the county after passage of the broader band of rain.
Thursday, March 21, 2019 - 4:02 PM - Another day another narrow line of showers - solid, but not as intense. Will have figures after it has passed. Yesterday's totals: Here at Banker's Hill: .24", SD Airport, .16", Encinitas .08", Escondido .34", La Mesa .09".
Wednesday, March 20, 2019 - 3:38 PM - A nice squall line preceded and followed by bright blue sky went through here in the last hour. Three lightning / thunders, a touch of sub pea sized hail, rain total: .24" in about 15 minutes.
Monday, March 18, 2019 - 9:25 PM - The Nitrous Oxide Levels data is in and has been posted. This completes the update for the year 2018 data.
Tuesday, March 12, 2019 - 8:59 PM - The Olivenhain total for the rains ending March 7 was .33". Last night's rain was more concentrated in south SD county. The Olivenhain gauge recorded .31", while the Bankers Hill gauge had a very impressive .79"! Storm totals: here .79", SD Airport .62", Encinitas .30", Olivenhain .31", Escondido .35", La Mesa .15".
Thursday, March 7, 2019 - 8:33 AM - Had .09" of showers overnight bringing the total to .15".
The methane date for 2018 in now in and yesterday I updated the Annual Average Methane Levels chart. See Methane Levels.
Wednesday, March 6, 2019 - 5:02 PM- The storm predicted for today has been underwhelming locally. So far here: .06" and some of that may have been dew, and as of 4:10 PM elsewhere: SD Airport .01" and that was yesterday afternoon, Encinitas .12", Escondido .25", La Mesa .03". Up north, particularly at the San Bernardino County mountains, the amounts have been copious with some stations getting more the 2".
Note: Overnight on Sunday March 3 going into March 4, another .02" fell in the Banker's Hill area.
Sunday, March 3, 2019 - 7:05 PM - Final totals: Here (Banker's Hill) .31", My Olivenhain gauge .61", SD Airport .17", Encinitas .41", Escondido .62", La Mesa .33". Predicted amounts for the next storm (mostly Wednesday) having been backed off due to a more northernly track, talk a something very significant a week from tomorrow Monday.
Sunday, March 3, 2019 - 12:25 PM - Rain totals for the latest round of rain starting early Saturday: here .31", Olivenhain .61". The totals were progressive higher from south to north. SD Airport just .17", other cities as of 5:46 AM: Encinitas .39", Escondido .61", La Mesa .32".
Thursday, February 28, 2019 - 9:25 AM - The U.S. Drought Monitor weekly update came out this morning. Just about all of California is now drought free! First time in years!
Friday, February 22, 2019 - 7:56 AM - Had showers starting late Wednesday, a lot yesterday with a few briefly intense, ending last night. Total here .35" (.03 Wednesday night, .26 through yesterday mid afternoon, .06 afterwards), SD Airport .22", Encinitas .22", Escondido .45", La Mesa .73". Finally, a dry spell is in the forecast, with warmer temperatures. Had ice in the bird bath Tuesday morning, at least the third time this winter. Frost this morning, at least the third time this week. Meanwhile, total rain here since late November 13.1"! Don't have figures for Olivenhain.
Monday, February 18, 2019 - 9:14 AM - Overnight showers brought the second shortwave totals to here.16" here, .SD Airport .09", Encinitas .15", Escondido .09", La Mesa .30". Esco's figure declined, probably something to with cutting off the totals as of the beginning of Sunday putting uncertainty on the other figures as totals.
Sunday, February 17, 2019 - 10:54 PM - Brief but heavy showers with strong cold winds have buffeted the area. The showers are still on radar to the west. Rain here as of around 9:30 PM: .10", SD Airport .04", readings as of 7:31 PM Encinitas .15", Escondido .10", La Mesa .17". A lot more in the mountains with heavy snows in the higher elevations.
Saturday, February 16, 2019 - 4:15 PM - A shortwave last night dropped .09" here, SD Airport .07", Encinitas .10", Escondido .08", La Mesa .10", very consistent figures.
The gauge at "SkyRanch" is will be henceforth known as Olivenhain. It had 2.85" in it late this morning. As it is located about half way between Encinitas and Escondido the total is consistent with the other two figures: Encinitas had a two storm total of 2.2" and Escondido 3.4", the average of the two was 2.8".
Thursday, February 14, 2019 - 9:04 PM - Final Feb 13-14 storm totals: Here 1.59", SD Airport 1.06" (lowest of the SD country coastal stations), Encinitas 2.10", Escondido 3.32"(!), La Mesa 2.27". Since late November I've recorded 12.40" here, well above normal for a year.
Thursday, February 14, 2019 - 1:03 PM - What a storm! Besides heavy rains, particularly in north county and over the mountains, the winds have been impressive, sustained 20-30 MPH with gusts over 40 for the last 10 hours or so. No major damage locally although there are reports of trees down around the county plus stream flooding. As of about 20 minutes ago my gauge recorded 1.25" for the storm. Much higher amounts, as mentioned, to the north and east. I was at Hotel Del Coronado this morning, video at https://www.instagram.com/johnstokesiii/
Wednesday, February 13, 2019 - 4:01 PM - Just took a reading. We've already had just over .25" here at Bankers Hill.
Wednesday, February 13, 2019 - 2:04 PM - The rains have begun for what is forecasted to be a storm well in excess of one inch! 2-3" are currently forecasted for the coast and valleys. I won't be around to take measurements tonight, will have an update mid-day tomorrow.
Last Sunday we had another .02" at Bankers Hill.
I've started to put the day of the week in front of blog dates to help navigate in the future.
February 9, 2019 - 5:33 PM - Finally got to the "Sky Ranch" gauge. 1.47" since the February 3 read with probably some evaporation. May have had a couple hundredths today. Had .02" today at Bankers Hill.
February 5, 2019 - 8:30 PM - There were showers overnight, some this morning and just a few light ones this afternoon. Since the last measurement, I've recorded .24", bringing the third storm total to 1.31". The NWS hasn't listed third storm totals, rather a 6 day scoreboard. Using that and subtracting the totals I posted here on Feb 3, I get:
Third storm / 6 day totals as of 4:02PM today: Here 1.31"/2.77", SD Airport 1.16"/2.50", Encinitas .29"/2.00" (seems really low for the third storm), Escondido .82"/2.80" and La Mesa 1.28"/3.20". There are still a few shows offshore. Saw a rainbow a couple hours ago...
Will be interesting to see what the Drought Monitor posts this Thursday, I really can't see us even being "abnormally dry"; last Thursday we were still at
February 4, 2019 - 9:12 PM - Showers have continued. My read is now 1.07" since the showers began late yesterday. Five day storm total here at Bankers Hill 2.53".
February 4, 2019 - 2:22 PM - A bunch of showers have gone through since late last night. As of 2:10 PM the Bankers Hill gauge has .63" new rain. Airport looking similar, .64" as of 1:51 PM. This .63" puts my since-late-November total to 10.03", easily a normal amount for a year and part of a trans-formative situation for California's chronic dryness. So now I'm contending with 3 foot high dandelions, stinging nettle, mallow and other weeds growing rampantly, particular in neglected areas.
February 3, 2019 - 6:08 PM - Final total for the second storm (mostly on February 2) here at Bankers Hill .86". The total since January 31, 1.46". Up at SkyRanch the total for this period was exactly 2".
The first and second storm totals for my selected list: Here .60"/.86", SD Airport .62"/.72", Encinitas .81"/.90", Escondido .77"/1.21" and La Mesa 1.08"/.84". My total since late November 2018, 9.46"!
February 2, 2019 - 11:43 AM - Getting blustery as the storm approaches. So far scatter light showers which started late yesterday evening. 04" in my Bankers Hill rain gauge, did not empty it. I'll be going to "SkyRanch" soon, will have the storm total for Bankers Hill tomorrow afternoon. I have an Instagram page at https://www.instagram.com/johnstokesiii/ where I've been posting selected charts and occasional cloud pictures.
February 1, 2019 - 1:36 PM - The December sea level data arrive later yesterday and I've now updated and posted the 2018 data at San Diego Sea Levels . The average level was virtually the same as last year, while the up trend remains intact.
January 31, 2019 - 9:38 PM - Storm totals are in: Here (Bankers Hill .60", SD Airport .62", Encinitas .81", Escondido .77", La Mesa 1.08" (one of the highest readings in the county). Looking forward to the widely anticipated rains this weekend, mostly on Saturday, February 2.
January 31, 2019 - 5:19 PM - The first in a new series of storms, with some lighting and thunder at the onset, has dropped .53" here (Bankers Hill) as of about 5 PM. At the airport as of 4:51 PM the total is .57". A few more showers remain to pass through. Been an excellent winter!
Meanwhile I'm still waiting for the December sea level data before I can post the 2018 annual update to the San Diego Sea Levels section.
January 18, 2019 - 5:22 PM - Wrapping things up for the recent series of storms. Last night I received another .04" and the final read showed another .06" early this morning for .10" additional. That brings the 3rd storm to .31" the same as the second storm and 1.25" for the three.
Final five day storm totals nearby areas: SD Airport .85", Encinitas 1.44", Escondido 1.83", La Mesa 1.27".
NWS is suggesting there might not be any more rain for the remainder of the month.
January 17, 2019 - 8:14 PM - Looks like the third storm is done - very tame here, mostly drizzle or heavy drizzle. North county and counties up the coast a lot more. Total in my Bankers Hill gauge today as of a few minutes ago: .21".
Bankers Hill summary:
Totals elsewhere in last 24 hours as of 7 PM elsewhere: Airport .09", Encinitas .29", Escondido .35", La Mesa .28". Spots in north country received well more than an inch. California overall very nice figures.
Four day totals are super impressive with the mountains receiving 4-6" in a number of spots. As of 4:02 PM: Airport .70", Encinitas 1.30", Escondido 1.75", La Mesa 1.06"
January 16, 2019 - 11:59 AM - I received an inquiry a couple days ago about data sources for weather models. I'm sorry I lost the email or can't find it on any social platform. At this time I use very few sources.
I read the NWS discussion (includes occasional discussion of the weather models) for San Diego at least once a day at https://www.wrh.noaa.gov/total_forecast/getprod.php?afos=xxxafdsgx&wfo=sgx&version=0&font=120&toggle=dictionary

There are many other links for satellite and radar imagery.
January 16, 2019 - 9:48 AM - Bit behind here. Yesterday morning I measured another .12" at the Bankers Hill gauge bringing the first storm total to .63".
I then went to "SkyRanch". Up at SkyRanch I'm not sure when I last measured the rain. There was .9" in the gauge as of yesterday afternoon - there must have been days of evaporation compounding things, that gauge needs to be replaced as it has a wide top. This morning there was .56" of new rain.
Back in San Diego now, I just measured .31" for the second storm. So the total here for the current series of rains is .94".
January 14, 2019 - 7:36 PM - The first of three recently advertised storms is just about done. The NWS backed off their over 1" prediction this morning, lowering it to .5" to 1" along the coast. The rain has stopped here, although there are a few light showers off the coast. Current storm total is .51". The second storm is predicted to go north of us for light, if any, rain here; the outlook for the third storm is less certain, although it looks like we will get something.
My total here since the November 29th storm is now 7.17"!
Storm totals as of 6:01 PM elsewhere: Airport .41", Encinitas .32", Escondido .65", La Mesa .66".
January 13, 2019 - 2:19 PM - A little behind here! Early yesterday morning a nice band rather uniform rain went through San Diego County.
Storm totals: Here .32", Airport .43", Encinitas .44", Escondido .64", La Mesa .32".
The NWS has been upping the totals for the next storm, scheduled to arrive late Monday, with numbers now advertised as well above 1"! The ground around here is very moist and there have been some small cliff collapses at the man-made cliffs in the Reynard Way area.
January 9, 2019 - 2:14 PM - I have updated the annual charts for Carbon Dioxide Levels
January 6, 2019 - 12:42 PM - Last night we received a ton of rain! The first wave went through shortly before midnight. Sleep kept me from making an interval measurement run. The second wave was much heavier, very heavy in fact. The airport recorded .52" in the 3:51-4:51 AM hour. This morning I checked the gauge and the 1" tube was completely full! I emptied that and the overflow when poured in added another .43". We received 1.43". The airport had the highest storm total for the coast at .90". When the heavy rain woke me up I checked the radar and a small cell was right over us. For the second time in this rain season it looks like my gauge takes the prize for the most rain (second place was Birch Hill with 1.37")! My less reliable Acu-Rite gauge also recorded 1.37". Rain amounts on a pool cover and some containers confirm the fat rain amounts. Since November 29th of last year, my gauge has indicated 6.34" of rain here. Everything is super green, happy plants everywhere!
Storm totals: Here 1.43", Airport .90", Encinitas .46", Escondido .66", La Mesa .71"
January 1, 2019 - The final total for the yesterday's rain here was .19". Airport .24", Encinitas .28, Escondido .07 and La Mesa apparently zero as it didn't show up on the NWS storm total list.
I have posted the final airport totals for 2018 at San Diego Rain, the year came in at 7.65". The wonderful December rains bailed out the year from having really low numbers. My yard is still lush! I have updated the annual charts for San Diego Temperature, San Diego Rain, and Arctic Sea Ice for 2018 with added commentary. I'm still waiting for end of year figures for Sea Levels, Carbon Dioxide, Methane and Nitrous Oxide.
Monday December 31, 2018 - 3:54 PM - So much for my "virtually certain" about there being no more rain this year after reading the forecast! I measured .04" here. There was .01" at the airport, nothing in Encinitas, .08" in Escondido and .01" in La Mesa. A few showers are still lurking off the coast. Tomorrow I'll update the annual charts for San Diego Rain and San Diego Temperature and other figures as they become available.
Friday December 28, 2018 - 9:03 PM. I have now returned from a family vacation at Big Bear. We had about 4" of sleet and thundersnow on Christmas Day! I wasn't able to check the rain gauge here in Bankers Hill until today. .27 inches in the gauge, presumably all on the 25th. San Diego airport received .18 inches. It is virtually certain there will be no more rain here this year. However, I'll wait to update the monthly data and the yearly chart at San Diego Rain until after the year ends.
Sunday December 9, 2018 - 8:15 PM. The December 5-6 total for "Sky Ranch" (halfway between Encinitas & Escondido) came in at just 0.90".
Friday December 7, 2018 - 2:43 PM. The final storm total here came in at 3.44" including .25" additional last night. Just incredible! Efforts to contain soil erosion were mostly successful, however one spot where the dogs went gopher digging generated a breach in a berm. Adding last week's 1.03" we've had 4.47"!
The previously leading SD University Heights station is not included in the most recent storm summary report.
Thursday December 6, 2018 - 8:42 PM. This storm merits yet another post. .37" more since the last reading. This brings today's total to 2.3" and the storm total to 3.16". The rains are light now although there are still some moderate cells lurking on the radar. Looks like the airport received 1.47" so far today and a storm total of 2.27". We're located not that far away, local terrain must have played a role (upslope valley opening to the south, with the cells moving to the north). Plus we had a direct hit from the thunderstorm which dropped just more than an inch in one hour.
I see that at 8:02 PM the NWS posted storm totals for other locations:
So my total of 3.16" is the highest in San Diego county? My problematic Acu-Rite gauge which typically records 10 to 15% higher than the analog gauge has been operating recently and it shows 3.68" buttressing the official 3.16" figure. Also we use some kiddie pools to collect rain water and they have about 4" in them, of course their sides are a bit tapered. My area has been such as dog over the past couple years. About time. Yay!
Thursday December 6, 2018 - 7:10 PM. Deluge!!!!! A bit over an hour ago the rain gauge was showing .84". Just checked it. Full at 1". Emptied in and poured in the water at the bottom of the larger container. Another .93". Storm total now 2.79". Week's total now 3.83".
Thursday December 6, 2018 - 6:13 PM. Huge thunderstorm just passed! Nothing like being outside in darkness, teaming down rain, with super loud thunder crackling just a second or two after the world lights up, followed by a dozen car alarms going off. About 1/2 hour ago today's total reached .84" bringing the storm total to 1.7" and the way the rain continued we should be well past an inch for today. We have a system of berms and swales directing the water down our slope, it was maxed out, so I turned the valve to direct the water to some Eucalyptus trees. Still raining quite hard. Dare I say too much rain!
The main show should be over soon, I'll get another read later this evening. The SkyRanch gauge will be read on Saturday and posted here on Sunday.
Thursday December 6, 2018 - 8:03 AM. Showers overnight dropped .18" here, bringing my storm total to 1.04". This brings the one week total to 2.05"! Still more to come. Happy camper.
Wednesday December 5, 2018 - 7:49 PM. The rain stopped here around 6PM and shortly afterwards I took a reading, .86"! I then emptied the gauge. The NWS posted storm totals as of 5:01 PM and the leader was University Heights with .76" just beating out my .75" reading taken around the same time. So after a seemingly chronic streak of rain-envy, the SD airport did very well and my own gauge did extremely well.
Wednesday December 5, 2018 - 5:12 PM. Took a bit longer for the rain band to get going here, but it really cranked up. About 10 minutes ago I measured almost exactly .75" in my Stratus Precision Rain Gauge! A perfect rainstorm for the yard - long periods of light to moderate rain, soaking everything. I'll take another reading after the band passes, probably in an hour or so looking at the radar. Still raining nicely here.
The 5PM readings around the county show .70" at the airport (the highest reading on the country map! https://www.cnrfc.noaa.gov/images/countyPrecipMaps/sandiego_24HRprecip.png , .62 at Encinitas, .64 at Escondido and .51 La Mesa.
Wednesday December 5, 2018 - 8:02 AM. A band of rain is approaching, just a couple hours away at most. The current coastal rain forecast today through Friday is 1 to 1.5"! Weather models are not in complete agreement and numbers were lowered from the prior forecast. Hopefully the predicted amounts will hold. Certainly going to get some rain this morning!
Sunday December 2, 2018 - 10:46 AM. Friday afternoon .02" fell here bringing the storm total to 1.03". Last night a trace, inland areas received more, generally 1/4". The reading from SkyRanch was 1.26" for the Nov 29-30 storm. The current forecast is talking 1-3" for the coastal strip this coming Thursday, and perhaps another system after that!
Friday November 30, 2018 - 7:17 AM. Had some good showers last night, adding .34" here, bringing the storm total here to 1.01". There are still some showers around. Published storm totals as of 4:15 AM: SD Airport 0.74" one of lightest readings in the county excluding the deserts, Encinitas 1.02" and Escondido a very impressive 2.07". La Mesa also impressive at 1.73". I'll get SkyRanch's reading later today, but due to computer logistics won't post it until tomorrow afternoon. San Diego country is going to turn a nice deep green!!!
Thursday November 29, 2018 - 3:26 PM. The front has passed, the sun is out with a lot of cumulus. Showers remain in the forecast. My Bankers Hill gauge received another .42" since this morning's reading, a bit less than hoped but still savored, bringing the storm total to .67". The airport had less rain overall, with their storm total as of 3PM at just .53". The two other cities I monitor had more, Encinitas .86 and Escondido .92. The usual pattern of the coastal areas receiving less rain than the mountains and the north receiving more the the south held to tradition with many mountain readings in the 2's. The pre-frontal winds were a lot less than advertised, I doubt we had a gust in excess of 20-25 MPH.
Thursday November 29, 2018 - 9:47 AM. The storm is upon us! Early morning rains dropped .24" at the airport and .22" each in Encinitas and Escondido. At my Bankers Hill gauge I measured .25" right in line with the other readings. A strong cold front is on the way per current radar, all areas should receive at least another 1/2". I'll be checking the SkyRanch gauge on Friday. NWS has done a great job with this storm.
Wednesday November 28, 2018 - 6:03 PM. Waiting for the rain! Rain gauges at the ready, and the swales of our permaculture system refreshed (silt cleaned out). The hydrology section of the NWS forecast for San Diego issued @ 1:47 PM this afternoon said "Through early Friday, rainfall is expected to range from around one inch near the coast to 2 to 4 inches in the mountains. Isolated rainfall totals of around 5 inches will be possible on favored southwest facing slopes. Around one half inch of rainfall is expected in the high desert areas and one tenth to one quarter inch in the lower deserts."
The main rain is to come with the frontal passage late tomorrow morning or early afternoon. Right now there are stars and clouds; radar shows light rain north of LAX. Waiting.....
Friday November 23, 2018 - 9:43 AM. I now have a second location with a rain gauge, at a place I call SkyRanch, about one-half way between Encinitas and Escondido. Yesterday, my main gauge in Bankers Hill recorded a very pathetic .01" same as the airport. Most of San Diego county received quite a bit more. SkyRanch recorded a wonderful .46" more than either of the two cities mentioned.
After the rain - November 22, 2018
Saturday October 13, 2018 - 9:59 AM. Another shower, moderate this time with some offshore lighting arrived later yesterday, before midnight, plus a few sprinkles gave us another .23" overnight per this morning's reading, bringing the total here to .65". Encinitas just .15" and Escondido .39". The airport's current 24 hour total is .48". Finally we did well! May be enough to green things up a bit? However, a fairly strong Santa Ana event is forecasted for this Monday and Tuesday. Hopefully the flora won't be too confused.
Friday October 12, 2018 - 9:47 PM. THUNDERSTORM!!!!!! Some rain with embedded thunderstorms moved up from the south in the last hour and half. Plenty of distant lighting and thunder and about 10 minutes of fairly heavy rain fell here. Just checked my analog Stratus Precision Rain Gauge with a 10x funnel, .42" and then emptied it. Just a few drops falling now. My Acu-Rite is a total fail, shows zero. Radar show more cells off Baja moving north, may be get some more rain before this is over! The airport is showing .35" in the hour ended @ 8:51 PM. Looks like this is a coastal event so far.
Friday October 5, 2018 - 1:32 PM. RAIN!!!!! Well some very light sprinkles passed over San Diego Country last night. The airport took home the prize with .09", and I measured .06", our first rainfall in a long time. Edit: since early May.
Last week the remnants of Pacific Hurricane Rosa passed south and east of here bringing altostratus clouds, humidity and dreams of heavy rain. There was a trace amount here, that is I felt two large raindrops while working out side, but nothing remotely near wetting the ground. It's quite rare for Pacific hurricanes to get close to San Diego. But.... the next one in the alphabetical list, Sergio, is up and about and may tease us again. Will be monitored of course. The consensus spaghetti plot has it tracking to the south and east again.
Thursday October 4, 2018 - 8:21 AM. Rain showers north of us, Encinitas .63, Palomar Airport .52, Escondido .42. Here, absolutely nothing.
Saturday September 1, 2018 - 10:58 AM. The climate data for August is in, August 2018 was the warmest in San Diego history, averaging 78.1 degrees, breaking the old record of 77.4 set in 1983. Much of the record heat owes to very warm ocean surface temperatures which kept the lows of the days well into record levels for a week.
Completing the record streak I posted on August 9:
I don't think any more records were set in August although there were some more ties for highest low: August 22: 74 (1984), August 23: 74 (1984), August 24: 73 (1984). I don't have access to daily record information prior to August 22.
Thursday August 9, 2018 - 9:13 PM - Very warm weather continuing, perhaps convincing people that climate change is real.
Ocean temperatures at Scripps Pier has been setting records, yesterday 79.2 peak, very well above the average surface sea temperature in August of 68!
Wednesday August 1, 2018 - 10:51 AM - July had some exceptionally warm days here in southern CA with some shockingly high temperatures on July 6 (San Diego 96 breaking the record by 13 degrees, Ramona with an all time high recorded anytime 117). The month averaged 75.2 degrees, 5.1 above normal, this after several months of near normal temperatures. July's 75.2 was the fifth warmest July going back to the 1850's, all five in more recent years: 1981, 1984, 1985, 2006 and now 2018.
Saturday June 30, 2018 - 3:30 PM - The July 1 through June 30 rain season is over as far as I'm concerned, no chance of rain for the remainder of the today. This rain season is the second driest since records began in the early 1850's, with just 3.4" for the last 12 months. The 2.99" in the 2001-2002 was the only one drier.
Thursday May 17, 2018 - 10:14 AM - This morning the Drought Monitor at http://droughtmonitor.unl.edu/ updated the drought intensity for the San Diego area from "Moderate" to "Severe". The last time San Diego was rated "Severe" was on January 31, 2017.
Saturday May 11, 2018 - 1:04 PM - A brief mid-morning shower associated with a thick marine layer "dumped" .01" here, matching the airport.
Wednesday May 2, 2018 - 11:20 AM - Showers! Overnight and this morning both my gauge and the airport recorded .11" of rain. The .11" was measured by my Stratus Precision Rain Gauge - see and measure the column of water with your eyeballs. The electro-mechanical Acu-Rite gauge says .26" fell, I'm certain this is wrong, as various buckets and other areas where rain puddled confirm something like .11". I'm no longer going to monitor the Acu-Rite gauge here. There's a chance of "wrap around showers" this afternoon, despite the areas of blue sky.
Tuesday May 1, 2018 - 10:32 AM - The airport did get .01" yesterday evening, doubling the month's total to .02", and the seasonal total to 3.28". My rain gauge had about 1/4 of .01", that goes down as a trace. Showers are in the forecast for later today / tonight.
Monday April 30, 2018 - 1:54 PM - Looks like we are going to close out April with just .01". Scattered showers could come in late tonight and tomorrow, so it's too early to post .01" as the official figure for April. Assuming just .01" for the month, this will bring the rainy season total to just 3.27", now the 2nd driest since records began in 1852. The record holder is 2000-2001 with just 2.99" inches. That record will stand, there was no rain in May or June 2001. Despite the run of extremely dry weather, the reservoir levels in CA continue to be in excellent shape, due to the heavy rains of the2016-2017 winter and continued storms tracking well north of us this winter.
Thursday April 19, 2018 - 1:30 PM - Weak windy system went through this morning. Airport .01", just about all stations had less than .10". My gauge not even .01", about 2/3 of a hundredth! Guess we can call that .01". Sun has already dried the heavy trace out. No rain in the forecast for the next week.
Friday April 13, 2018 - 5:03 PM - Last week another storm went to the north, there was some chance of light showers here but no rain came. Yesterday another storm went well to the north, we had a light trace here as correctly predicted, the first raindrops of the month. The dry season is practically upon us, so unless we get some outlier rains between now and June 30, we are looking at one of the driest rainy seasons (July 1 through June 30) since records began.
Today I updated my Time Lapsed Lichen section, a project started 15 years ago. See Lichen Project.
Sunday March 25, 2018 - 9:31 PM - The 20% chance of showers this weekend came to another ZERO at the airport and little if anything in the rest of the county. Nothing here. Beautiful crisp day today! The rainy season (July through June) total so far is 3.26" at the airport, way below the normal of 8+ inches, the 5th driest since records began in 1852 assuming no more rain this month.... this month of March at the airport so far is .95", and it is very unlikely there will be more given the current forecast of sunny days for the rest of the month.
Friday March 23, 2018 - 9:50 AM - Both rain gauges recorded .01" overnight. Storm total .02" here. Airport a trace yesterday, their storm total, ZERO! May get some showers over the weekend, but chances are 20%. The CA reservoirs are in great shape with most of them at 100% or better than normal for this date. Snow pack is below normal.
Thursday March 22, 2018 - 9:54 PM - The downgrade trend was not our friend. San Diego NWS had a 100% probability of rain today and the airport's total through 9PM is ZERO! They probably had a trace, and there are still some showers moving to the north and south of the Cone of Dryness which may break through and post a positive number for them. My new totally analog see it with your eyeballs rain gauge had almost exactly .01" in it! (as of a few hours ago). My old electro-mechanical gauge is showing zero. Most of California north of San Diego county received a lot of rain, the atmospheric river struck the state as predicted, just not here!
Thursday March 22, 2018 - 9:40 AM - Rain is just off the coast headed this way, finally! Meanwhile another downgrade last night, this time to .4-1"; this morning's forecast isn't out. Judging by the radar, .4" looks quite doable (10:11 AM edit - maybe not, bulk is moving north of us). Yep, the 10AM forecast says "Overall the storm total precipitation amounts have been lowered a bit especially in the southern area" - well that's been going on for two days, now .25-.5" a long ways down from 1-3". Basically the rain activity of the southern tips of troughs are very hard to predict and my experience is they are almost always overestimated at the start.
Wednesday March 21, 2018 - 10:02 PM - This morning's upgrade in predicted rain was a head-fake, this afternoon we were back to .5-1" and this figure remains with this evening's forecast. Meanwhile nothing has fallen and the plume is still north of L.A. My rain gauge did arrive today and I have it set up in a preliminary location. Will post a picture after I have it set up in a permanent location.
I've updated the 2017 Methane Levels charts. Basically the methane levels data appears to be the same as the preliminary data. The extreme outlier reading of last November 22 was deemed valid and I included that figure when creating the charts, increasing the average for 2017 slightly. This completes the work for 2017. For 2018 so far, Arctic Sea Ice is tracking slightly less than 2017 with the latest figure a record low by small margin, Carbon Dioxide Levels continue at new highs for the date, San Diego Temperature have been cooler so far this year than last year and I think that's true globally, San Diego Sea Levels data is notoriously late, the January figure about 9/10" lower than last year.
Wednesday March 21, 2018 - 10:31 AM - The atmospheric river continues to inch south towards us. NWS now saying "about an inch" for the coast, this is an upgrade. Yay! Plus the Thursday rain probability last night was increased from 70% to 100%. Will set up our kiddie pools for rain catchment later today. My new rain gauge is supposed to be delivered today, just in time!
Tuesday March 20, 2018 - 10:49 AM - Two more downgrades for the amount of rain here, sigh. Yesterday morning for the SD coast was 1-3", then yesterday afternoon .5-2". Then last night .5-1", and now .25-1.5". The last was a widening of the range, but a drop in the lower amount shows NWS concern that the chances for a miss are increasing.
Meanwhile, the official 2017 Methane Levels data came in, will update the chart after I have processed the file.
Monday March 19, 2018 - 4:58 PM - Yesterday I ordered a Stratus Precision Rain Gauge, supposedly to NWS standards and accurate to .01". Should arrive tomorrow before the rains start. About those rains. Yes a really nice Pacific storm is out there and the forecast includes a "strong atmospheric river". When these strike San Diego, we easily get an inch or two of rain. The "problem" with this one is that it is predicted to mainly hit central CA then drift down, almost as a front by the time it gets here.
This mid morning's forecast hydrology section said 1-3 inches for the San Diego coastal area. Today's 3:03 PM forecast hydrology section says
San Diego County (coast & valleys): 0.5-2 inches Upper Deserts: 0.75-2 inches Coachella Valley: 0.25-1.00 inches
So the coast has been downgraded. The problem with this type of forecast is the exact location of the river. Years ago when I lived on the East Coast, the winter challenge was predicting the exact location of the rain/snow line, 50 miles make a big difference in a nor'easter! Looks like that is the case with atmospheric rivers, a couple hundred miles is a big determinant. Anyway, anything is welcome. An inch would be great!
Saturday March 17, 2018 - 3:29 PM - My weather station lost its connection to the Internet in the early hours of the morning after .05" fell and when I rebooted the antennae the total was reset to zero. I've decided I'm going to get a good old fashion cylinder for measuring rain. Anyway, we had several hours of nice rain here in the early morning hours, probably very similar to what fell at the airport, which received .27". Again we were on the low side compared to other areas in the county, for example Escondido received .66". Another bout of light rain is predicted for late today, and "more significant" rain around Thursday, but of course that far out the signal to noise ratio can be problematic. So far we're muddling along in March, but if we do get the significant rain later next week the month could start looking decent and be the first "above normal" month of the wet season drawing closer to the end.
Thursday March 15, 2018 - 10:15 PM
Still waiting for the official 2017 Methane Levels.
Sunday March 11, 2018 - 10:11 PM - Returned today from a three-day trip to the Monterey CA / Big Sur area, beautiful! Saturday saw .43" in my rain gauge, .36" fell at the airport. Nothing today.
Saturday March 3, 2018 - 2:53 PM (edited) - Two bands of rain moved through the area, one in the wee hours of this morning and then a sharp short shower in the late morning. Unfortunately my weather station stopped communicating w/ the Internet for a while and shows zero precip for the first wave, we definitely received some rain for an hour or so. Airport shows .09" for the first wave and .14" in the second. I recorded .13" for the second wave. I'm now in the process of upgrading my Acu-Rite weather web connector as I received an upgraded controlled a few days ago.
Tuesday February 27, 2018 - 11:19 AM - Winter storm moved through last night, with .26" between 1 and 5 AM. Since then a couple shower each added another .01" to bring the total here to .28". Airport showing .32". Many coastal and inland areas received a fairly uniform .55-.65" with snow in the mountains. Reports of light hail in some cells but nothing like that here, in fact we are on the lower end of the precipitation scale. Showers are still around. Nice thing is another storm is forecast to go through late this week with more than just trace amounts. However, there is just one more day in February and unless a freak shower comes along we will end up way below the normal of around 2": the wettest month of the year.
Friday February 23, 2018 - 9:42 AM - We've had continued occasional traces of rains with cooler, windier weather. Yesterday shortly before 2PM a brief shower with a few minutes of nice rain brought in .04" here (.03" at the airport for that shower, also .01" later at night, nothing here), and this morning a shower with .01", nothing at the airport. So my February month-to-date figure is .06", and the airport .04", pathetic for the month. Inland has seen higher figures yet again; also a few days ago showers brought 1/4" type figures inland with nothing here. Talk of more significant rain keeps getting pushed back in the forecast.
Thursday February 15, 2018 - 10:53 PM - Had two brief periods of scattered raindrops yesterday. The afternoon period was a heavy trace - ground wet but zero measured at the rain gauge. San Diego airport also had zero.
Tuesday February 13, 2018 - 10:11 PM - The waves of showers which went through San Diego yesterday morning and last night, were disappointing. Nothing yesterday here, and .01" this morning. So here we are almost halfway through February and we've received just .01" so far this month here on my gauge, and zilch at the airport. Other areas of the county received nominal amounts yesterday and today, but overall everyone is well below normal. This winter, of course, is also well below normal, but that one nice rainstorm we had in January is keeping us out of record territory. My guess is right now we are in about a one-out-of-10 situation. I'll have a better "score" after February's totals are in.
Meanwhile still waiting for the official Methane data for 2017.
Monday February 5, 2018 - 10:19 PM - I received a fascinating graphic from NASA regarding an extreme methane event in 2017. See Methane Levels for further details.
Saturday February 3, 2018 - 8:14 PM - I have received preliminary data for Methane Levels for 2017. While processing the preliminary data, I discovered I made a big mistake last year for the 2016 data. The methane level increased substantially in 2016, did not decline! The 2017 preliminary data shows another increase to another new record although not as big as the 2016 increase. I've corrected the charts for 2016 and have added the preliminary data for 2017 at Methane Levels.
Friday February 2, 2018 - 8:53 AM - January 2018 averaged 61.5, the second highest in history, 2003 was higher at 61.7. We're back to prolonged no-rain, been three weeks not including the two .01" events. Rain 1.78" for the month at the airport, .2" below normal.
Friday January 26, 2018 - 10:57 AM - Yesterday afternoon, brief line of showers went through, .01" here and at the airport. Month's total here 2.05", very likely done for the month.
Monday January 22, 2018 - 10:29 PM - NOAA continued to operate during the brief government shutdown. New data is out and I have updated the San Diego Sea Levels page for 2017 (sea level rise trend is intact) and I also updated the Nitrous Oxide Levels page for 2017 (upward trend is intact). Still waiting for end of year figures for Methane.
Monday January 22, 2018 - 10:26 AM - Rain associated with a trough on January 19 dumped a grand total of .01" here, matching the airport.
Friday January 12, 2018 - 4:17 PM - have updated the Carbon Dioxide Levels page for 2017 (record setting trend intact).
Friday January 12, 2018 - 10:47 AM - My rain gauge's final total for the recent rainstorm was 2.03": .19" on the 8th, 1.78" on the 9th and .07" on the 10th. The airport had .16", 1.57" and .02".
Tuesday January 9, 2018 - 5:13 PM - Another surge of moderate to almost heavy rain is in progress! Meanwhile I did find a way to retrieve prior rainfall. Yesterday's total was .19", more than my guess of .15". Today so far 1.60", storm total 1.79".
Tuesday January 9, 2018 - 10:59 AM - Wow did we get rain! My rain gauge recorder resets at midnight and unfortunately the month-to-date function is not working, so I'm not exactly sure how much fell yesterday. The airport received two sets of .07", so I can make an educated guess and say we receive about .15" yesterday given the first set of .08". After midnight the heavens opened up and by about 1:45 AM we had an inch. Since then the rain has tapered off to widely scattered showers. Todays total is currently 1.37", bringing the storm total here to about 1.52". Just what we needed! Yay! The airport is showing 1.34" storm total as of 9:51 AM. BTW, the NWS was saying the heaviest rain would accompany the frontal passage - didn't work out that way, as by far most of the rain came in well advance of the front - but a congrats is due, as this rain was indicated almost a week ago! We're still well short of normal for the season and a new stretch of dry weather is predicted. Still, I expect the ground cover seeds we spread last November to finally germinate and robustly so.
Monday January 8, 2018 - 10:11 PM - A forerunner spritz from the much advertised and much needed storm dropped .07" at the San Diego airport, .08" here, late this afternoon and early evening. .75" to 1.25" total predicted for the local coastal plane with most to fall tomorrow morning with the passage of a front. We'll see!
Friday January 5, 2018 - 10:03 PM - Rain is in the forecast for next Tuesday! My rain gauge is calibrated and ready. Meanwhile there has been just .09" since the official starting date of the rainy season (October 1), the driest on record, going back to 1850.
In the past few days I have updated the San Diego Temperature page for 2017 (warming trend intact), and the Arctic Sea Ice page for 2017 (Arctic ice coverage shrinking trend still intact). I'm still waiting for end of year figures for Sea Levels, Carbon Dioxide, Methane and Nitrous Oxide.
Friday December 30, 2017 - 3:23 PM - I've posted the rain charts at San Diego Rain for 2017, the year coming in at 7.92" a couple inches below normal. The June-December stretch came in at just .19", setting a new record low for this time period going back to 1852. We are now about 1/5 into the rainy season by normal volume, we all want rain!
Friday December 22, 2017 - 11:30 AM - No rain is predicted for the remainder of this year. If this prediction holds, we will have the second driest Oct-Dec period since records began with .10" compared to 1929's zero. However 1929 had .26 in September and this year we had just .07 (corrected from .08). Also, in June of 1929 there was zero, this year .02". So the Jun-Dec of this year is likely to come in at .19" (corrected from .20") breaking 1929's. .26". The following January 1930 had a fat 3.90", nothing is yet on the horizon for January 2018.
Wednesday December 20, 2017 - 10:09 PM - What timing on my rain gauge calibration! Showers moved through here this evening. Received .08", airport .07". Might be a few more sprinkles but I think that's it. Might be it for the year! Still might set a record for the driest June-December.
Tuesday December 19, 2017 - 2:02 PM - I finally took down my Acu-Rite rain gauge, brought it inside, disassembled and clean it, and then calibrated it. It is now within 1% of spec. Prior to calibration, by testing it after cleaning it and putting it back together, I found it to be just shy of 20% over reporting. This confirmed my suspicion as I more than not reported more than the airport, here.
Sunday December 17, 2017 - 9:37 PM - Since the first of June through today, we have had just .15". If we receive no rain in December, this will be the driest May-Dec in San Diego history! The first half of December has been the warmest in San Diego history, and this year California has had some of the worst fires in recorded history. Will this pattern change? This evening the NWS says: The weekend looks like a transition period with higher uncertainty as the hemispheric pattern begins to undergo a rather large shift. Both the 12Z GFS/ECMWF runs appear to be hinting at establishing the massive EastPac ridge farther to the north, allowing shortwave energy to undercut. How this energy manifests itself remains to be worked out, but it will at least keep us cooler and tamp down the persistent dry offshore flow we have been experiencing this month. The shift in the ridge, if it does occur as seems to be indicated, will also open the door to Pacific systems that could eventually bring much needed precipitation.
Thursday November 23, 1:22 PM - Yesterday's high was 92. The record for today is 86 and was tied per the hourly readings a few hours ago. Some cooler air is coming in from the sea along the coasts. Still no rain in the forecast, rather another Santa Ana next week!
Wednesday November 22, 3:48 PM - Went up to 91 today (going by the hourly readings), setting a new "hottest so late in the season" record for the San Diego airport and smashing the old daily high for this date of 83. Note: I'm looking for a list of record high and low temperatures for San Diego going back to I think 1878 when temperature records were kept. The record dates in my file are all pretty much past 1935-1940 for both highs and lows and I am suspecting I don't have a comprehensive data set. Contact me at email@example.com. I realize the weather station has moved around over the years.
Wednesday November 22, 12:37 PM - Already 88 degrees at the airport, breaking the record by 5 days and if we go to 90 it will be the hottest ever so late in the season. Meanwhile the forecast indicates November will have no measurable rain for the month. We really need rain, our yard was begging for the usual November rains. A zero for November is not unprecedented, the record shows previous occurrences in 1872, 1878, 1894, 1903, 1904, 1929, 1956 and 1980 so we were actually overdue for a zero month! Of the nine occasions only one was followed by a zero December (1929). Zero Decembers are rare with just 5 occurrences recorded since 1878: 1900, 1917, 1918, 1929 and 1930.
Monday September 4, 2017 10:41 AM - The remnants of tropical depression Lydia passed by San Diego to the southwest as predicted, but the rainfall amounts were a lot less than previously mentioned. In San Diego country, La Mesa took the prize with .16", the SD airport .03" in three .01" events. Nothing registered in my gauge, although some surfaces suggested we received more than a trace.
By the way, the images from the GOES 16 satellite are super cool, I became aware of this website a couple weeks ago: http://weather.cod.edu/satrad/exper/?parms=swzoom-02-200-1
Following the incredible recent record rains from Hurricane Harvey in the gulf, all eyes now switch to Hurricane Irma. The models keep nudging her to the west with the hurricane to perhaps pass near the Florida Keys in about a week then turn more towards the north and affect the Florida panhandle and beyond.
Saturday September 2, 2017 - 6:56 PM - After more than three months with hardly any rain, looking forward to see what the remnants of tropical storm Lydia can bring to the area. Currently an 80% chance of showers tomorrow with .10-.75" a likely range. Lydia is projected to pass well to our southwest as a depression, bring the strong northeast sector very close to our area.
Monday May 8, 2017 - 9:50 AM - Final storm total my gauge 1.12", .89" airport. Many readings of 2" or more inland!We're now in great shape to go through the dry season even if there is little or no rain until October-November. The 2017 YTD airport total is now 7.7"!
Sunday May 7, 2017 - 8:23 PM - Excellent rain all afternoon into this evening - Today so far now .98" here, bringing the storm total to 1" exactly. SD Airport showing .70" through 7:51 PM. Fruit trees will be VERY happy.
Sunday May 7, 2017 - 11:15 AM - Rain! First rain event here since the light rain we had in late March. Yesterday .02" here versus .05" at the airport. Today so far .18" here versus .21" at the airport. North county and inland mountains quite a bit more with some amounts over an inch. More is in the forecast, hit or miss variety.
Thursday March 23, 2017 - 12:15 PM - Had .04" late last night, bringing the "storm" total to .11". Airport .07" total. Only slight chances of rain for the remainder of the month.
Wednesday March 22, 2017 - 4:23 PM - The "storm" a total bust locally. The NWS repeatedly lowered expectations for the rain, and so far we're below the lowest of the low. Here .07" in the gauge, .04" at the airport. Looks like March will come in well below normal. I've been hoping for one more good storm before the dry season is upon us.
Monday March 20, 2017 - 2:46 PM - Spring began today at 3:29 AM! Been a dry month, with the .01" on March 5 all there is to show for this month so far. Normal for the month is around 1.55"! But, rain is on the way, with the bulk forecasted to fall later in the day Wednesday. Projections from the 1PM NWS forecast:
Coast and valleys-0.75 to 1.5 inches Mountains-1.5 to 3 inches High deserts-0.25 to 0.50 inches Low deserts 0.25 inch or less
Sunday March 5, 2017 - 8:31 PM - Extreme southern tail of a frontal system went through today. 01" at the airport, .00" in the rain gauge, just a trace on the ground.
Thursday March 2, 2017 - 1:36 PM - The drought level for San Diego dropped again, now we are just "abnormally dry", the lowest drought code.
Tuesday February 28, 2017 - 10:00 AM - The storm ended last night around midnight, with a final super heavy burst in the mid to late evening. My rain gauge recorded 4.71" for the day! And just .01" after midnight this morning. The buckets, a more reliable measurement, were close to 4". It rained every hour yesterday, unlike the typical San Diego pattern of bursts of rain with broken clouds and bits of sky in between. The airport recorded 2.35". I read that the San Diego river crested at the 3rd highest level recorded. In our lower yard, a hunk of "the cliff" collapsed. Looking forward to this Thursday's drought report! Will post comparison pictures when it comes out.
Monday February 27, 2017 - 12:42 PM - The storm is turning into a major headliner! My buckets are showing 1.5 to 1.75", the rain gauge 2.15", the airport as of their latest report @11:51 AM showing 1.07". Certainly at least 1.5" here.
The date for the second drought picture in the February 2 post was incorrectly mentioned as January 1, 2017, now corrected to January 31, 2017.
Monday February 27, 2017 7:35 AM - Yesterday, in the first of two advertised rains, I measured .03" here, the airport .05". The second storm is upon us and already has produced far more than originally predicted and much more is on the way. My gage is showing .92" right now for this morning and a steady rain is falling! The bucket looks like about 3/4".
Monday February 20, 2017 9:16 AM - I was in New Orleans during the big Friday storm of February 17 returning late last night! My gauge measured 1.54" on Friday and then .30" more for the weekend's showers. As usual I think this is high, but certainly over an inch fell here! With the heavier rains in the L.A. area I'm looking forward to yet another reduction in the drought designations for CA this Thursday.
Thursday February 9, 2017 4:45 PM - A another drought level reduction in the San Diego area occurred today, we are now in the color between yellow and orange, indicating "moderate" drought!
Tuesday February 7, 2017 2:39 PM - The first rain event of February appears to be over. Airport .13" with .03" in the first stage and .10" in the second stage. My gauge .22", all in the second stage (last night). No buckets were set up. As usual, a lot more rain in the mountains and to the north. We may see a further reduction in the drought designations within California this Thursday.
Thursday February 2, 2017 11:10 AM - The drought monitor has continued to greatly reduce the drought severity for California with major improvements as a result of the rainy December and January.
U.S. Drought Monitor November 29, 2016 & January 31, 2017
Thursday January 26, 2017 3:13 PM - San Diego Sea Levels has been updated for 2016. The average sea level reading dropped by about 2.5" for the year, but the average reading was still the third highest going back to 1906. The prior two years contain the two highest readings! The trend remains up. The drop in 2016 was likely due to the end of the latest El Niño influence. The 2016 updates are now complete.
Wednesday January 25, 2017 12:15 PM - The airport is now showing 3.01" for the month, .05" yesterday. I recorded .12" yesterday. For the month I've recorded 6.72", my guess is actual is closer to 5" here. The weather outlook is for clear skies for the rest of the month, so 3.01" will likely be the total for January, 7.23" for the last two months, and 8.23" for the season which is at least 2" above average.
Monday January 23, 2017 1:29 PM - Nitrous Oxide Levels have been updated for 2016. The slow but relentless increase continues.
Monday January 23, 2017 10:01 AM - After two direct hits by small cells, my range gauge storm total is now .89". Bucket nearly matching with 7/8". Airport a laggard with .44". North county was deluged, Palomar showing 6.19", the extreme case; Temecula 3.16".
Sunday January 22, 2017 9:50 PM - Methane Levels have been updated for 2016. 2016 levels declined from last year and was the first average level decline since 2006. 2016 was still the second highest average in since records were started in the late 1980's. Still waiting for Sea Level and Nitrous Oxide data.
Meanwhile a front just went through and we had quite a bit of rain in the last hour. My gauge is now showing .70" inches!
Sunday January 22, 2017 7:49 PM - So far the storm has been a flop locally from a rain perspective. The heavy rains have remained to the north, only a little bit "crept" into our area. LAX has over 2.8" and many areas in north county well over an inch. The airport reading as of 7PM is a pathetic .11", my gauge right now is showing .24". The winds are still strong from the south, certainly a front will go through sometime and could bring some strong frontal rain. The big rain shield in advance of the storm is now pretty much inland. The winds have been impressive, over 20 MPH all afternoon and early evening, with gusts in the 30's.
Sunday January 22, 2017 11:39 AM - The second storm lived up to the hype. In the first wave of rain Friday morning I recorded .71", in the second very heavy wave in the afternoon, 1.13" inches completely maxing out both systems of hillside swales and berms, then .17" in showers on Saturday morning, for a storm total of 2.01"! The bucket total was around 1.75". The airport recorded 1.11" on Friday and .03" on Saturday - my total for Saturday was a lot higher due to a direct hit by a small vigorous cell, plus on a micro scale rain funneled up the valley from the south. We had some strong winds too, but no damage or big branches down.
The third and final storm was supposed to be here about now, but the rain this time is creeping to the south as rain cells are moving to the northeast unlike the previous storm which had cells moving more to the east. Next week's drought report should finally take San Diego down a notch!
Thursday January 19, 2017 - 2:06 PM - The first of three storms has passed. While the county did receive 1/2 to 1" mostly to the north, local amounts were underwhelming. Airport .19" about the lightest anywhere along the coast as the initial rain shield of yesterday evening split into two, passing mostly to the south and one piece to the north dissipating. My gauge .33", bucket about .25". The NWS remains bullish for the next two storms, Friday and then Sunday.
Wednesday January 18, 2017 - 3:36 PM - The text file for rain totals at San Diego Rain has been corrected. The total for 2016 was 10.23" not 10.44". In my spreadsheet I had May as being .65" when it was really .44". The text file had the correct number. Thanks to Jay Hansen for alerting me to the error for 2016.
Wednesday January 18, 2017 - 9:58 AM - Looking with anticipation for the three storms predicted to hit starting tonight through next Tuesday. As of this morning, preliminary NWS predicted totals for the three storms is super impressive:
I did get .01" more rain later in the day on January 13.
January 13, 2017 - 10:55 AM - January is following December as a rainy month. Our yard is full of very happy plants loving it, plus weeds! My total for yesterday and last night into this morning is 1.16", bringing my monthly total to 3.30". The airport is showing .55" for the latest storm, and only 1.04" for month to date. The bucket is back and is showing about an inch for the latest storm. Meanwhile the U.S. Drought Monitor's latest weekly update is showing northern CA (north of San Francisco) as being drought free for the first time in years, and a considerable reduction of the "Extreme Drought" area to the south. We remain categorized as in "Extreme Drought". Perhaps this most recent storm and yet more rain possible late next week will generate a lowering of the drought rating for this area.
January 11, 2017 - 10:00 PM - Carbon Dioxide Levels have been updated for 2016. The levels reached a new record and the annual increase was the third largest since records began in 1958.
January 11, 2017 - 6:13 PM - Some light rain this afternoon: .14" in my gauge, .05" at the airport. One more system is in the forecast for tomorrow/Friday with the current projection at .25-.50".
January 9, 2017 - 11:36 AM - San Diego once again brushed by a vastly larger center of rain to the north. 0.18" in my gauge and .18" at the airport so far, looks to be about over. On January 5 recorded .25" here, the airport .16". The "bucket" gauge has been discontinued for now. Two more systems are in the forecast but neither one major.
January 3, 2017 - 12:13 PM - Arctic Sea Ice has been updated for 2016. The average coverage dropped by 3.79% to a new low. The maximum coverage was just a tick greater than lasts year's record low maximum figure, while the minimum was 5.6% lower than last years minimum but short of the record minimum set in 2012. I'm still waiting for Carbon Dioxide, Methane and Nitrous Oxide figures.
January 2, 2017 - 3:17 PM - San Diego's 2016 temperatures are in, 2016 was the 6th warmest with the three year average of the three most recent years the warmest on record. San Diego Temperature has been updated.
January 1, 2017 - 5:38 PM - My total for the three phase rain came in at 1.57", with .22" in the first period, .32" in the second period and 1.03" for yesterday evening;s rain. The bucket figure was similar overall. The airport end up with 1.16" overall, 4.22" for December and 10.44" [Jan 18 Edit: Correct figures is 10.22"] for the year, above normal! With so much rain over California this past year, maybe we can get rid of the area of "Exception Drought" and lower San Diego's "Extreme Drought" designation to "Severe" or maybe even better! San Diego Rain has been updated.
December 31, 2016 - 10:13 PM - Rain resumed late this afternoon, been a great day! Airport through 9:51PM is showing .58" for today and certainly will be more than that. My gauge as of right now is showing .94" and 1.48" for the last two days. I have the airport breaking 10" for the year with 10.34" so far. 'Lite have the final figures and updated chart tomorrow. Bucket is showing more than an inch for the Dec 30-31 period so far. Happy New Year!
December 30, 2016 - 3:43 PM - Nice band of rain went through here this morning associated with an upper level low. Airport .28", my gauge .22", bucket maybe 3/16". This rainy December brings the airport total for 2016 to 9.53", very close to normal (9.85") and very close to last year's total of 9.89". If we score direct hits from the tail end of this system and the system forecasted to go through tomorrow, we might hit 10" for the year, the first time since 2010.
December 24, 2016 - 11:14 AM - The final read for the second storm (Dec 21-22) was 1.10" for the airport, 1.96" for my gauge, and about 1.5" for the bucket. Last night's storm came short of coastal expectations of 1-2" locally as the main blobs of rain split and went north and south of here. The airport is currently showing .61", my gauge higher again at .86" and the bucket a touch over 3/4". There are still a few widely scattered showers about.
December 22, 2016 - 11:08 AM - A lot more rain! Right now the airport is showing .98" so far for this storm. My gauge says 1.68", again I think that is high, but we did get a lot. My "bucket" gauge is showing about 1 1/4". The storm last week registered 2.10" on my gauge, 1.32" at the airport and about 1 3/4" in the bucket. May still get some more showers out of this surprise"Baja" storm, then maybe an inch from the "Alaska" storm late Friday into Saturday.
December 21, 2016 - 5:25 PM - Excellent forecast - rain tonight and tomorrow morning, then a "major winter storm" during the night of December 23-24.
Rain approaching from the south, late afternoon December 21
December 16, 2016 - 11:44 AM - The NWS nailed this one! Although the rains were a few hours late, they did come. Lindbergh is showing .90" of rain so far. My Acu-Rite rain gauge is working again and shows 1.33"! However, I think that is high, a well placed bucket with vertical walls is showing about 1". In any case a wonderful soaking rain with very little runoff. I expect an explosion of green in the yard next week.
December 15, 2016 - 11:51 AM - NWS has been predicting rain here for almost a week. Latest has rain starting after 5PM and ending tomorrow with .5 to 1.25" along the "coastal basin". The Pacific satellite imagery at http://counterintelligence/Storm/Hurricane/Pacification is not too promising, the movement so far has been to the north us as usual. The "100 percent" chance of rain tonight has been reduced to "90 percent", tomorrow is still at 100 percent. We need rain locally! Meanwhile substantial rains again are falling in northern CA, the reservoirs are full or nearly full. Here's hoping for an inch!
November 29, 2016 - 4:09 PM - Generous rain fell in San Diego North County, about an inch, and exceeding more than 2 inches in the Julian / Cuyamaca areas. But, locally (nearer the airport), amounts were far less. My gauge is still down, San Diego International Airport (also known as Lindbergh), received .11" on Nov 26, .17" on Nov 27 and .10" yesterday, Nov 28. I think we received about the same maybe a little less. I can dig a couple inches into garden mulch and the ground is still bone dry! No rain will fall tomorrow, so I can say that November's total will come in at .61", about 1/3 inch below normal.
November 20, 2016 - 3:50 PM - Rain is predicted! Not clear how much is predicted here, but 1/2" seems to be possible as the amounts have gone from 0.2", 0.4", 0.5" then ranging from 0.25" to 0.75", then no figure mentioned, and then most recently "four to six hours of heavy precip with rainfall amounts exceeding 1/2 inch per hour will be possible", but without location attribution. 2015 turned out to be a good year after years of drought, then this year much drier again. Our yard needs rain so badly. The system of berms and swales we built on the hillside went untested last winter due to the failure of the El Niño rains to materialize.... maybe this rain will do it.
November 2, 2016 - 11:08 AM - October came in almost bone dry with .07", well below normal. Nothing on the horizon for November. We need rain! Center and northern CA did receive very good amounts. Also, October was 3.9 degrees warmer than average. Particularly disturbing is that the Arctic Sea Ice has returned to a path of record shrinkage as the Arctic Ocean's sea temperature is way above normal. If we do not get a big freeze up there this winter, next summer could see some very dire readings.
September 20, 2016 - 7:14 PM - Rain today! Worked its way from the south very slowly and fell in my area as generally light rain all afternoon and into the evening with pauses. My rain gauge is not working (still shows 0.00" on the display). My guess is we've had somewhere between .1" and .2" so far.
September 19, 2016 - 11:57 AM - Impressive thunder and lighting around 3AM this morning! Forerunner activity from hurricane Paine off the coast of southern Baja. On the lookout for showers tonight! Raindrops last night but zero as measured in my rain gauge, maybe .01" actual. Prior to today, there has been virtually no measurable rain since May 6th, that's over 4 months without rain. We need it badly!
June 1, 2016 - 7:40 PM - Been dry since the last entry, just a few traces here. Lindbergh recorded .01" towards the end of the month.
May 6, 2016 11:28 AM - Rain! Showers went through late yesterday evening, I recorded .10". Today some good steady rain in the early morning followed by another line of showers a short while ago added .55" here, bringing the storm total to .65". The rain was much needed here, the plants in my yard will be quite happy! The airport is showing .43" so far for the storm, well about the normal for the whole month of May, the second year in a row this happened.
May 2, 2016 11:43 AM - The subsequent systems mentioned on April 7 all flopped. So the year got off to a great start with the 3.21" of rain in January, then fizzed with February-April bringing in just1.36" at Lindbergh compared to a normal of 4.86" And now the dry season is upon us.. The ground is dry up driving up the need to irrigate again. Northern California is in great shape with the huge Shasta and Lake Oroville reservoirs approaching capacity!
April 7, 2016 6:50 PM - The advertised wetter weather is upon us. I recorded .30" of rain so far today, this compares favorably with Lindbergh's .27". More showers are nearby, and three additional systems are fore-casted to arrive in the next week.
April 1, 2016 1:51 PM - March saw just .76" of rain, 1.01" below the NWS normal for the month. We may get some tropical rain in a week, but surely El Niño has to be considered a flop so far for water hungry Southern California. For Northern CA, the main reservoirs are now ABOVE normal for this date, a huge relief for that area! My rain gauge recorded .82" for the month.
March 7, 2016 9:31 AM - Well once again San Diego has to settle for the southern tails of the storms. Yesterday I measured .18" and in today's much anticipated storm, only .16" from the front which just passed through here, although the rain was briefly heavy with some lightning and thunder. Central and northern CA again have received considerable rains, severe drought conditions up there have lessened substantially.
March 1, 2016 10:32 AM - February set a new record as the warmest February in San Diego weather history. The average temperature of 63.9 broke the previous record of 63.5 set in 1980. In third place is 63.1 set just last year, So 2 of the 3 warmest Februaries have been in the last two years. The two coldest February were set long long ago: 50.4 in 1894 and 50.5 in 1880!
February was also one of the driest February with just 0.05" inches of rain. Not extremely unusual, as there have been eight Februaries with lower amounts going back to the mid 1850's, with 1912, 1924 and 1967 at zero. The good news is that the weather models are predicting considerable rain starting as soon as March 6. Current talk is 1" along the coast in the following week, perhaps more!
February 11, 2016 4:25 PM - 10th day in a row of super dry weather. Third day in a row of record heat. Feb 9 - 83 broke record of 77 set in 2008; Feb 10 - 86 broke record of 84 set in 1988; today - 84 broke record of 83 set in 1988.
February 9, 2016 5:20 PM - We've had 8 days in a row of increasingly warm super clear weather, virtually cloudless and very dry. The generous rains of January are drying out and once again we need rain badly although the northern reservoirs are doing well. We had a record high temperature today, although the previous record of 77 was a record waiting to be broken as the typical record high around now is in the mid 80's. Today 83. At my place, just slightly further inland than the airport, I recorded 92 as the high!
February 1, 2016 1:55 PM - The San Diego Sea Levels data for 2015 is out! Again the collective data flashes a warning for global warming. The levels for 2015 set a new record. While big increases are frequently followed by decreases, the trend has been up, and the last two years certainly jump out! Also, on January 29 Arctic Sea Ice was at the lowest levels for that date since recording began around 1980.
January 25, 2016 2:18 PM - The Methane data for 2015 is out! And alas, once again a new record was set for the year, plus the increase was the biggest in 24 years. See Methane Levels.
January 24, 2016 - Been about two weeks since we've had any rain (except .06" on the 14th, bringing the monthly total here to 3.74" and a few traces). There's talk of a fairly good chance of a rain event at or near the end of the month. Meanwhile still waiting on Methane and Sea Level data to close out 2015.
January 18, 2016 10:40 PM - The December CO2 data is in. I've updated the Carbon Dioxide Levels page, adding the 2015 data to the main chart, and I created a new chart showing the change in parts per million for each year since records began in 1958. 2015 not only set a new CO2 level records, it also had the biggest increase since records began, breaking the 3.0 parts per million barrier.
January 12, 2016 12:26 PM - Did the annual update for the Nitrous Oxide Levels chart, another increase. Still waiting on the CO2 data for December. 2015 CO2 will show a record level for sure and disturbingly a good chance at a record increase for the year! Will post the data when I see it. Also still waiting on December sea level data, that will likely show up in a couple weeks. No idea when 2015 Methane data will be out. Meanwhile we are back to a dry pattern, the jet stream is pushing the El Niño storms well north of us again. Still, with 3.68" of rain so far this month, we are well above normal.
January 6, 2016 8:15 PM - Another rainy day although the main action was to the north of San Diego, including multiple waterspouts off the coast to the north. I have measure 0.69" since midnight, and there must have been another .02" late yesterday as the January total is now 2.93". Showers, possibly strong, are predicted for tonight.
Meanwhile I have updated the Arctic Sea Ice page for 2015. Noteworthy is that the maximum ice extent for 2015 was at a record low, while the average and minimum were low but not records.
January 5, 2016 9:26 PM - What a storm! I measured 1.98" today, and just now a little squaw has brought the total up to exactly 2 inches, with the total since all this began a couple days ago to 2.22". Had some flooding issues on the property.
January 5, 2016 - Finally! El Niño enhanced storms are upon us. I received .22" from the first and weakest of the storms (.16" initially then .06" in residual showers). Rain gauge is in south Mission Hills. Storm number 2 is in progress and I've picked up .18" as of this morning with a coastal forecast of 1 to 1.5" and 2 to 4 in the mountains. Storm 3 is expected to be strong, too and a fourth one this weekend!
January 1, 2016 - Year 2015 average temperature was 67.50 and almost set a new record but not quite, as 2014 came in at 67.54 degrees.
December 31, 2015 -
Rain: San Diego came in a just about normal for the year regarding rainfall. The super unusual thing about this though is that most of the rain fell in the normally very dry summer!
Temperature: San Diego was on track for having its warmest year on record, but with a rather cool second half in December, I think we are going to miss breaking last year's record by just a few hundredths of a degree! The last two years are the warmest back to back years in San Diego. Globally, Earth set a new record high average temperature for the year.
Sea Level: In late January the ocean level data for December San Diego will be coming in and will be posted on the Sea Levels page. Based on the first 11 months 2015 will be well above 2014's record by more than an inch!
Carbon Dioxide: CO2 was at a new record last year yet again (will update as soon as I get the update).
Methane: Methane could take months, my source was very late last year. This year has seen a huge methane leak in CA, currently unplugged. The Aortic Sea Ice extent looks to come in at the third lowest, although the current year-end level is at a new low.
Summation: Things continue to get worse. Go solar, eat less meat, recycle and re-purpose.
December 23, 2015 - Northern CA, Oregon and Washington have received super impressive rains this past month. Here in San Diego, amounts along the coast have been light, although some mountain stations have received 2-3". My rain gauge is now operational, although not yet working for the Internet (transmitter not being picked up by the "Internet Bridge"). In the past few days it recorded .34", with .11" a few days ago and .23" in the most recent round. These figures are very close to Lindbergh Field's .11: and .20"!
December 14, 2015 - Waiting for El Niño!. We had .19" on December 11 (mixed with pea size hail and some thunder and lightning) and .16" yesterday evening, bringing the monthly total to .35". But this is -.21" below normal so far for the month. Northern CA has had a lot of rain this month, but so far the reservoir levels have barely budged, they continue well below normal throughout the state. We may see some rain in a week, but the forecasts at this time are not talking a big event. Longer range continues to keep rain well to the north.
I have recently purchased an ACURITE weather station! Not yet set up, hope to be able to connect my station to the Internet for data sharing! At some point in the future I plant to migrate my environmental section from this website to a new website and make it publicly interactive.
November 4, 2015 - Heavy rains in May, July, September and now continuing the every-other-month streak this November, substantial rain fell in the San Diego area yesterday evening. Bringing memories of the thunderstorms last July, about four thunderstorms went through San Diego yesterday evening accompanied by many flashes of lighting and booming thunder, scaring the dogs. Combined with some earlier showers and later sprinkles, the storms dropped 1.12" at the airport, most of it in a couple hours. The storm came from the cold Alaskan climes and was not tropical in nature .I've been working on having our sloping yard terraced for water catchment and yesterday's storm caught us with an incomplete system! I have San Diego's year-to-date total at 8.59", and is well ahead of the last three below normal full year totals of 6.63", 5.57" and 7.77".
November 2, 2015 - October's San Diego average temperature came in at 74.4 degree's smashing the previous record of 72.2 degrees set in 1983 to smithereens, with records going back to 1851. Again and again, evidence continues to pound us in the face that a serious warming trend is in place.
October 19, 2015 - Amazing factoid from the National Weather Service:
SUNDAY [October 18, 2015] WAS THE NINTH DAY IN A ROW WITH A LOW TEMPERATURE OF 70 OR GREATER AT LINDBERGH FIELD AND THE 10TH SUCH DAY SO FAR THIS MONTH. PRIOR TO THIS YEAR...THERE HAD NEVER BEEN MORE THAN TWO DAYS IN A ROW IN OCTOBER WITH A LOW TEMPERATURE OF 70 OR GREATER IN SAN DIEGO AND NO OCTOBER WITH MORE THAN FOUR SUCH DAYS...THAT BEING OCTOBER 1997 WITH FOUR LOWS OF 70 DURING THE FIRST FIVE DAYS OF THAT MONTH. THIS RECENT STRETCH OF WARM NIGHTS HAS BROUGHT THE 5 WARMEST NIGHTS IN OCTOBER IN THE HISTORY OF SAN DIEGO AS WELL ASTHE 7TH WARMEST.
October 13, 2015 - San Diego continues with well above normal temperatures. September, according to my records was the 32nd consecutive month above normal! In the last four days San Diego record 99 degrees, a tie, 96 degrees, a record, 94 degrees, a record, and 94 degrees, a tie. Some record high low temperatures were set. So, October is on track on becoming the 33rd above normal month in a row. NOAA says that February, March, May, June, July, and August of this year have set monthly all time records for monthly global average temperatures. Is the ongoing global warming accelerating?
In the rain department, today's forecast mentions a good chance of a significant rainstorm on Sunday, October 18th.
September 15, 2015 - The remnants of hurricane Linda finally made significant landfall, causing September to join May and July as freakishly wet months during what is normally the dry season for San Diego. A wave of rain swept in from the sea today penetrating well into San Diego county. San Diego airport received 1.07" of rain in just two hours and 1.15 in all, through mid evening.
The five month period of May through September this year has been the wettest in San Diego recorded history! I have the five months (with September only half way done) coming it at 5.30", the previous 5 month record with September being counted as a full month was 3.95" in 1977.
September 8, 2015 - Been mostly dry since the big rains of July. July ended up with 1.71" and August just .01" (about normal) with some early showers mid month and nothing so far in September. Yesterday there were some pretty impressive towering cumulonimbus in east county and Agua Caliente had close to an inch of rain. Nothing here as mentioned. We are getting close to the end of the monsoon season. There is some tropical moisture to the southeast, will be on the lookout for more big clouds over the mountains.
July 19, 2015 - Yesterday was one of the most incredible days in San Diego weather history. Thunderstorms from the remnants of tropical storm Dolores struck San Diego for several hours bringing record rainfall amounts for July. The three wettest months for July going back to 1852 were 1.29" in 1865, .51" in 1868 and .92" in 1902. In the single day yesterday San Diego received 1.03" with hundreds and hundreds of lightning strikes. The previous record for the date was just .01". The average for the whole month was just .03"! Then today a new round of storms struck and as of 6:51PM .57" has fallen, bringing the month to 1.64", a record in recorded history. As of 6:49 PM it is still raining!
What is particularly incredible is that May had 2.39", the second wettest May in history. The May, June, July total comes to 4.07" smashing the previous record of 2.54" in 1921. So while California is considered to be in a very severe drought, the last three month must start showing up in the overall data, we've been having record rain!!
July 2, 2015 - There have been some early monsoon showers over San Diego county this week. .04" on the last day of June, kept that month from being a zero; .01" on July 1. Scattered heavier amounts elsewhere.
May 31, 2015 - The heavy rain predicted for May 15 did not materialize, May ended up coming at 2.39", 0.15" shy of the record set in 1921. Although San Diego officially is in "Extreme Drought" mode, the latest season's rain is less than an inch short of normal. Local vegetation is looking pretty green! The reservoirs though out California remain well below normal. Also the month came in a just about normal temperature-wise, breaking a streak of considerably above normals.
May 15, 2015 - Yesterday evening extreme rain fell at the airport and nearby locales. I was in north county so I missed the really intense part! I read that .71" fell in just 9 minutes at the peak, a rate reserved for intense thunderstorms and hurricanes! 1.30" fell in one hour, 1.51" in two hours, yesterday's total was 1.63". This is quite incredible considering the normal amount for the whole month of May is 0.25". The previous one day record for May 14 was .40". Blame the jet stream.
With the 1/2" which fell earlier this month, 1.63" yesterday and .18" through noon today, this month has already seen 2.31". Since records began in 1851, this total has been exceeded just once, 2.54" in 1921. Given today's forecast of more rain, this number could be easily broken. Will be interesting to see how plants react as they were already in summer desert mode.
The YTD figure is now 3.96", still well below the normal 6.35" for a full five months, but much better than a couple weeks ago. The seasonal total (July-June) is now 8.91" not that far off from the normal of 9.86". This rain has been mostly confined to Southern CA, overall the state's reservoirs remain well below normal.
May 8, 2015 - 1/2" of rain fell in San Diego in the past 24 hours, twice the normal amount for the whole month! Won't do much for the extensive drought but very, very welcome. Some hints that we may receive more towards the end of next week.
March 28, 2015 - March 2015 will set a new all time record high monthly average temperature record for March. The current record is 64.05 degrees and that was set just last year in 2014. Through the first 27 days, March 2015 has averaged 66.6 degrees, it would have to be in the high 40's for the last four days, this is not going to happen.
Since the last post some more records were set or tied:
March 16, 2015 - A record heat wave is ending
February 23, 2015 - A rainstorm came through San Diego county in the past 24 hours; it was completely out of the long range forecast last week. Dropped over 2" in the mountains and mostly over 1" in north country. South county didn't get much, and the SAN airport received a paltry .18", that rain gauge is well below normal year to date.
February 4, 2015 - Added Nitrous Oxide Levels data page.
February 3, 2015 - Added Methane Levels data page.
January 20, 2015 - Added Analysis sections to the Rain, Sea, Temperature and CO2 pages.
January 1, 2015 - I have 2014 as being the hottest in San Diego's recorded weather history going back to 1852, with 2014 beating the previous record of 67.24 by .3 of a degree.
December 31, 2014 - Only .08" at San Diego from the latest rain (corrected from .09"), but closer to an inch in some North County places. And snow inland! Will update the various charts in the coming days. Happy New Year everybody!
December 30, 2014 - The first 29 days of December have come in with an average of 61.1, the last two days would have to be pretty close to zero to fail to have a record warm year. However in one of the recent discussions, the Weather Service said that this year is shaping to be "one of the warmest on record", not the warmest on record. Hmmmm. Curious to know which year is the warmest so far since records began. According to my records, it was 1984 coming it at an average of 67.24, followed by 1983 coming in at an average of 67.04. My guess is 2014 will come in at around 67.54.
December 29, 2014 - Here is a correction to yesterday's post. December has to have an average of 56.99 degrees or above to set a new record (not 56.41 as mentioned yesterday). Still a new record is a given as yesterday's cold weather brought the first 28 days of December down by just .3 degrees to 61.2, and would require the last three days to be in the 17's to bring the monthly average to below 56.99.
December 28, 2014 - Colder than normal weather has been in this area for the past couple days with frost inland. The cold is predicted to persist for the rest of the year although not as extreme. Does this threaten 2014 being the warmest in recorded history? No, not by my calculations. I'm figuring December has to average 56.41 or above for the annual average to set a new record. For the first 27 days, December has averaged 61.5 well in excess of this. For the final four days to bring the average to 56.4 for "only" a tie, the final four days would have to average a frigid 22 degrees. Not going to happen.
December 20, 2014 - A third but smaller rainstorm mostly on the 16th, brought in 0.84" at Lindbergh, bringing the monthly total to 4.42" way above normal. Again there were much greater amounts well to the north. And today there is yet more rain in northern CA although nothing here. Reservoir levels, while improving, remain well below normal. The most impressive thing about the rain on the 16th was the spectacular rainbow which appeared shortly before sunset as the storm moved out. Visible was a fairly unusual "supernumerary rainbow" effect: interior fainter bows of color!
December 15, 2014 - With the first 14 days of December averaging 6.2 degrees above normal it is almost certain 2014 will come in as the warmest in San Diego weather records history. The remaining 17 days would have at come in at around 50 degrees average, super extremely unlikely.
December 12, 2014 - Another impressive rainstorm. 1.05" of rain at Lindbergh, about in line with the general area. Huge amounts of rain fell in central and northern California with many areas reporting 3 to 6". Plus, this time it was cold enough to bring snow to the mountains, to help build storage for next summer. Combined with the first big storm, maybe, finally, the extent of the drought shown at drought.gov will shrink. Already this month, San Diego has received well more than in the first 11 months. And more is predicted to come!
December 4, 2014 - A very heavy rain cell crossed the airport early this morning, dumping over 1" of rain over their poor rain-starved gauge within an hour, catapulting Lindbergh's storm total to the top of the heap for San Diego Country coastal stations! As of 4AM, the storm total for Lindbergh was 2.53" (corrected from 2.58").This brings Lindbergh in line with the rest of the county since early November, and with November doubles the year-to-date totals to over 6". Still well below normal, but now not freakishly so. Already there is talk of another rain maker around December 11-12.
December 3, 2014 - Best rain in quite some time. Bit unusual as the rain is from the tropics rather than the southern tail of a frontal storm. However, as usual, the heavier amounts are to the north and inland, with San Diego getting a less than expected. Still, amounts exceeding 1" or more are common with some mountain areas getting more than 3". Should be enough to bring about substantial greening of the landscape. Meanwhile the 10 day forecast is for above normal temperatures, so the chances of setting a temperature record for the hottest year on record for San Diego are increasing.
November 30, 2014 - If December comes in at normal temperature or warmer, 2014 will be the hottest year recorded for San Diego.
November 27, 2014 - Record high temperature in San Diego, 85 degrees, breaking the previous high of 83 set in 1903. I think we've tied 3 records this year and broken 6. This year is on track to being one of the warmest on record with an outside shot at being the warmest.
November 21, 2014 - Reports of heavy rain last night in some areas of San Diego county. Some places received more than in inch. Poor Lindbergh received just .04".
May 22, 2014 - We've had a bunch of record temperatures here - broken or tied. Fire storms accompanied the second batch. I was surprise today, San Diego county remained in "extreme drought" instead of being moved to the worst category "exceptional drought", by the USDA's weekly Drought Monitor update.
January 17, 2014 - For drought commentary along with monthly notes, scroll down to Recent San Diego Rain File Updates.
August 30, 2013 - I created a super cool time-lapse video of the weather for the last four days from mid Monday August 26, 2013 through mid-day Friday, August 30, 2013. In retrospect I should have let the video run through the end of the day on Friday as there were some cool clouds over the mountains later in the day.
July 23, 2013 - On July 21 there were some impressive thunderstorms in East County, with Agua Caliente receiving well over an inch of rain. But here along the coast, nothing. The next day was advertised to be a potentially explosive day with a clear morning providing lots of heating for convection over the mountains. I now have better equipment for doing time lapses and I ran the camera facing east for most of the day yesterday. In late morning things were looking up, but drier air began to move in from the coast and things went down hill from there.
Today I have the camera running in case something isolated pops up this afternoon, but so far very, very little activity.
September 7, 2005
Monday 6:10 pm - Another interesting cloud feature in the sky today, a "sun dog". I greatly increased the photo's contrast to show off the unusual streak extending to the right. I've seen a lot of "sun dogs", but do not recall ever seeing such a long associated ray.
Same picture, uncropped with no processing done and reduced in size - very close to how it appeared to me.
August 17, 2004
9:18 pm - Weapon of Mass Destruction detonated in San Diego! Well not really, but an innocent cloud transformed itself to a big thunderstorm with incredible speed! As soon as I saw the initial cloud, years, no, decades, of cloud watching told me to grab my camera as fast as possible and drive to a location to watch the explosion. Photo times, PDT.
6:18pm - Cloud discovered - drop everything!
6:29pm - I arrive at the Cactus Garden in Balboa Park, a good place for looking East
6:39pm - I gotta zoom out a bit to get all of the rapidly spreading anvil
7:02 pm - Storm continues to spread in both directions
However, convection in one area of the base of the cumulonimbus cloud, around 1/3 in from the left, has almost stopped
7:24pm - Passersby referred to it as a spaceship or nuclear bomb!
Note that the left side's "cauliflower" growth has almost completely ceased
7:29pm - After sunset, a fireball in the sky
Update: The National Weather Service wrote this evening: A SEVERE THUNDERSTORM ERUPTED OVER THE DESERT NEAR AGUA CALIENTE SPRINGS EARLY THIS EVENING AS A BRIEF PERIOD OF STRONGER WEST FLOW COMING THROUGH THE MTN PASSES INTERSECTED WITH SOUTHEAST FLOW OVER THE LOWER DESERTS. VERTICALLY INTERGRATED (sic) LIQUID VALUES AS HIGH AS 63 KG/SQ METER WERE DETECTED BY RADAR...AND THAT INDICATES LARGE HAIL. CLOUD TOPS WERE NEARLY 50000 FEET HIGH. THIS WAS EVEN THE CLASSIC "RIGHT-MOVER" WHERE SHEAR-RELATED PROPAGATION FORCES THE STORM TO MOVE TO THE RIGHT...OR SOUTH IN THIS CASE...OF WHERE THE WIND WOULD TAKE IT. HOWEVER...SHORTLY AFTER 730 PM...THE STORM COLLAPSED AND DISINTEGRATED.
