  1. Hi Everyone! Recently comments haven't been posting to the blog. I think it's some kind of bug within Blogger. I decided to delete everything and start fresh. Hopefully this works!

  7. It's snowing in the Sierra Nevadas. Hooray! We need the snowpack. But also wishing travelers a safe journey. If possible, it would be good to stay home for a few days.

  15. Can someone tell me what the current San Diego rainfall total has been so far for December of 2021? And if possible, what is the average rainfall for December in San Diego?

    Thank you in advance!

  16. Both Wunderground and Fox5 were forecasting some big rains for 12/29-12/30 but it just fizzled out

    Is this due to a new weather pattern that we are not yet familiar with? It seems all the rain got pushed up North

    ReplyDelete

    1. The system rode the coast as it moved south. It's going to bring the LA region a few inches of rain. Unfortunately, afterward, it is going to pull most of the heavy rain southward. A few showers are still possible through today and tomorrow, but it won't amount to much. Around .25" coastal and inland, near an inch in the mountains.

      Delete
  17. Dang I'm listening to the rain on the Monday evening... It's really nice to get some rain. I feel it was completely unexpected though, i had checked the Fox5 website earlier. It's the second downpour that was unexpected within a week

    1. I've spent the last few months getting my brewery built in downtown, so I've been on a hiatus. Things have calmed down somewhat now that we are open, so I should be ready for updates this upcoming rain season!

      Delete
    2. Wow! Your own brewery in downtown San Diego. So glad for you. I just found the name in your About section -- "East Village Brewing Company." And found your website -- that's a great location on Park Blvd by the ball park.

      Looks like you are getting ready to open -- let us know when you do. Will definitely stop by. Those frosty mugs sure look tempting on these scorching days we're having.

  20. Do you think you could reverse the order of comments so that the newest are first?

  22. Did comments quit working again?

  23. Hooray! Snow is on its way to the Sierra Nevadas this Friday. Will be checking the last map (percent of average rainfall so far this rain season) to see if we get some "greening" of those red and orange areas up north.

  24. Hello, would it be possible to have a map showing maybe a 3 year average precipitation? Or a line graph for the past few decades?

    1. That's a good idea. I have the 30 year averages in the climate section of this website. But a timeline would be nice.

      Delete
  25. Excited for these storms. Any idea if this will continue in Jan and Feb?

    ReplyDelete
    Replies
    1. The active pattern should last for a couple more weeks. It might slow down by the second half of this month. Long term, we are still in La Nina, which usually equates to overall dry conditions. Hopefully it erodes by the end of this season.

      Delete
    2. Since the overall pattern is La Niña for this season and if our current weather “erodes” it by the end of the season, then will we be more likely to have an El Niño season next season?

      Delete
    3. Aaron, great maps, thanks. Re La Niña; if the jet stream continues to funnel storms toward us due to its dip, and tapping into the SW for moisture, I would think the LN vs EN cycle is not as important? Regardless, nice to see the rain.

      Delete
    4. Valid question! There are always exceptions to the rule - you can have a wet La Nina, or a dry El Nino. When talking climate, you need to look at 30 year averages. Generally speaking, La Nina brings dry conditions to SoCal, however, this winter has been interesting to say the least. The La Nina is rapidly weakening to neutral conditions, so it makes you wonder if that's contributing to these rainy conditions.

  34. So if I read this right, San Diego has has about 15" of rain since 01 Oct 2022? Is that correct? And if so, what is the AVERAGE rainfall for the same period?

    ReplyDelete
  35. The average rainfall totals for SD is 10 inches per year (October-September).
    We are above the average now and we have 7 months left to go. We could realistically get 2-4 more inches of rain in the next few months (March-May) and end up with 12-15 inches or so for the rainy season which would make this a very good year for rain just like 2020 (12 inches total). Last year we only got about 5 or 6 inches of rain for the year. This is a great site!

    3. My weather station in Scripps Ranch is showing 19.11” since Oct 1 as of March 30th.

    4. That should have read as of March 20th. Typo.

  36. Will the rainfall throughout the rest of the state make up for the snowpack that the rains affected? How much of the pack has been lost due to flooding?

    ReplyDelete
  37. We've already hit 12-15 inches in the rainy season in the greater San Diego area from October thru 3/1. I would be surprised if we don't hit at least 20 inches, if not more by May. Many storm systems dropped 3-5 inches and there were at least 4 major storms over the last 3 months. Just last night/this morning in Escondido we've hit 2.5 inches with more projected early next week. I grew up in Seattle and this year has almost felt like the NW (almost).

  38. Hey Aaron! Can you explain the rainfall deficit hole in the Yosemite/Kings Canyon area of the PERCENT OF AVERAGE RAINFALL SO FAR THIS RAIN SEASON IN CALIFORNIA map. Is this a sensor anomaly or what?

    ReplyDelete
    Replies
    1. It's definitely bad data, which creates that illusion!

      Delete
  39. I've been wondering about that "rainfall deficit hole" as well. It appears centered around Lake Thomas A Edison. I've done some searching, but can't find any mention of this phenomenon or what may be causing it. (BTW, love checking this site every day!)

  40. I don’t know Aaron, I am used to you posting before any rain event so I’m doubting everyone who says there will be over 1” this weekend.

  42. Did these update after the tropical storm?

  43. He did post just before the storm hit, so all the indicators lined up. I was concerned he was so busy with his brewing that he put this blog on the back burner, glad to see it isn't the case.

    ReplyDelete
  44. Slow start for winter '23-'24 - at least down here in SoCal. Do you think it has to do with the delayed seasons that we have been having this year or are we in for a warm & dry winter?

    ReplyDelete
    Replies
    1. Great question. El Nino is still going strong, however, it doesn't guarantee a wet winter. The current storm track really isn't that great for big rain events. I don't see it breaking for at least another couple weeks. In the meantime, we might see occasional rain chances.

      Perhaps you're right and we'll see the rain delayed to late winter. We'll see!

    2. Can you add Alpine to the map? Thx!

    3. Does not appear the ytd or season to date charts are fully updated considering how much rain was dropped yesterday 1/22/24...

    4. I made the comments regarding YTD and STD, disregard as I just noticed that the graph header is through 1/21/24... it's the details that trip me up, great blog!

    5. After every rain event, I will post rain totals across the area. Alpine is definitely on that map. Thanks for stopping by!

    6. It looks like those statewide maps update every day in the afternoon. It's a tad slow, but very good data!

  45. The last storm really gave a boost to the rain totals for the season. Rain total since Oct 1 went from 2.18” before the weekend to 5.55” this morning.

  46. Great that San Diego County looks like it’s caught up to the expected rainfall for the season. It would be better though if the Sierra Nevada mountains seasonal totals were better, since that’s the state’s water supply. Snowpack is improving, but still below average so far.

    Fingers crossed…

    1. It's been a bad year for snowfall all along the Western US. I have farmer friends in Yakima who are worried about the lack of snowpack. Let's hope for improvement!

  47. Nicely presented. Thanks! Distinguishing between yearly and seasonal.

    ReplyDelete
  48. Question for you (by the way I love this page, I’ve followed for years) - for the percent rainfall of the year/season, is that point in time or for the entire time period?

    To clarify: is San Diego at 150-200% of its average annual rainfall for February, and that number will slowly drop if we have a dry month or two, or as of February, we already have 150% of rainfall for the entire year?

    ReplyDelete
    Replies
    1. Title is “Percent of Average Rainfall So Far…” so I would assume the latter. I am curious to know though how “average” for the year/season is calculated. Is this over the last decade? Or the last 20 years? Or ???

      Delete
    2. I meant, I would assume the former, not the latter.

      Delete
    3. Great questions! The first is for the calendar year starting January 1st, while the other is for the rain season starting on October 1st. Climatology is always based on a 30-year average, so the numbers are compared to the previous 30 years.

      Glad you like the blog and reach out with any further questions!
