Heat

[baseline bum]

One more day in the 80s with potential rain and now it's back to actual summer with mid to upper 90s and dry expected next couple weeks.

Knew it was way way too early in July to call this a cool summer prematurely. We just got to day 19 of 100+ today. The historical average is 18 and the last 30 years average is 21, and we have a heat dome parked over us for at least the rest of the month.

ing 106 forecast for Tuesday, 107 for Wednesday

[baseline bum]

It's not even ing 2PM yet

Knew the 104 forecast was too good to be true. 106 at the airport right now, 109 at my house. Heat index 117.

What a pleasant pre holiday week forecast

baseline bum, I'm back. And I was right about 2024. Aside from a few outliers, it's been a very wet, average-at-hottest Summer 2024.

Average would be 21 days of 100+; we had 27. You'd think with a hurricane and a tropical storm hitting we'd be sub 10 or at least below average but nope. Still ranks #14 on the list of years with most 100 degree days since they started doing the official temperature at the airport after WWII.

Only because of that outlier week a couple weeks ago but I believe the actual overall daytime averages were below as well as well above for precipitation

[Millennial_Messiah]

This time this year, we are seeing 80s daytime highs in early September with or without rain.

This time last year, we were seeing consistently 100+ and above at this point, early football season

That's just not the case, our summer is basically average on rainfall per this article from yesterday's Express News.

You're comparing to a year so hot it had more than half a month worth of 100+ degree days more than the hottest previous year ever recorded here and August was nightmarish this year until the last few days of the month.

August was "nightmarish" for about a week. The rest of the month it was a typical August in SA.

I don't even remember January being all that wet. I was however gone from around Jan 20th through Jan 24th for a court date out west on Jan 22nd

Typical August is 97

[Millennial_Messiah]

Typical August is 97

Which was roughly the average for SA in 2024 or less even counting the insufferable week because of all the rain and near-miss rain days in the 80s. Yeah humidity was higher than usual but you have to take one or the other.

Meanwhile this coming week in California (L.A. Metro) is seeing the 106, 107, 103 type days. Parts of Orange County and L.A. county could see 110's in the coming 7 days. And can't even pull the "but it's a dry heat" card because you're literally by the ocean. While SA will simultaneously be seeing upper 80s at the same time.

[Millennial_Messiah]

And Sunday and Monday early mornings actually look like hiking weather... mid 60s lows in early September in SA are practically unheard-of. Low humidity, too, but then it creeps back up early week.

Meh only time we were below 97 in August was when we were 96 on August 1st, 91 on August 26th and 27th, 93 on August 28th, 94 on August 29th and 30th, and 95 on August 31st, with only the 26th through 28th below historical average (93.7 is average by Aug 31). The 10 day for my old neighborhood looks pretty hot for LA but 82 at 7PM right now isn't a big deal. This is the hot season for LA when the Santa Anna winds blow in, and it is a quite dry heat since it's created from winds blowing in from the desert.

Also don't buy that mid 60s lows are unheard of considering historical average for low on September 7th is 71.8 and September 8th is 71.6.

They're definitely rare though and generally consistently in the 70s through the end of Sept. Overnight lows in summer down here are much more consistent than highs. It's not like Arizona when you can see some summer lows in the 60s and some in the 90s and everything in between. Less variance in subtropical humid climates like Texas, and even less variance in tropical climates like south Florida, Hawaii, or pick a tropical island near the equator.

No they're not. Historical average lows for San Antonio drop into the 60s by September 15th.

If it's a dry heat with low humidity, then theoretically wouldn't you see more nocturnal radiational cooling? I.e., much lower overnight lows. These late summer overnight lows are subtropical and bordering on tropical. For instance NorthCal and a place like Denver, Flagstaff etc is getting down to the low 50s at night, even upper 40s.

You're really comparing LA to cities that are 5000 and 7000 feet in al ude? Dewpoint is like 57 in LA right now.
