I definitely take it back when I said my place wouldn't see another mid-70's day before the rains started. I was too ready for fall lol.

But very happy to have my garden last longer and finish off the last of the tomatoes and squashes.

Wish I could say the same. The heat wave next week is wasted for me because of the frosts

It has been cold and dry for a long time. We had the 3 day May heat wave and then went back into the tank with the clear nights. 

It was literally one of our hottest May-August periods in recorded history…

This is my 7th year.  I also have 25 years of gardening records from the previous owner. This year is top 3 coldest and #1 driest

Do you mean since January 1st or the warm season?

Jan 1st. Summer heat was decent this year just short lived

It was cold from February through late April.   It was warmer than normal across the region from late April through mid September even using the 1991-2020 averages.    I think it was the 5th warmest summer ever at SEA (JJA).

Then the records I have are garbage. Either way latest/earliest frost for me in 7 years

Summer started in late April. May was record warm for the region. I guess it could be argued that summer ended close to on time this year which was nice for a change, but I certainly wouldn’t call five months of summer (late April-late September) short lived.

It mostly seems like you have unreasonable expectations for warmth that even our rapidly warming climate can’t quite meet.

Not sure... I guess late/early frosts can co-exist with also being a warmer than average summer.

This is possible.

I know that if you thought this summer was cold then you would have hated years like 2008 and 2011.   This summer was significantly warmer than those years... at least in the Seattle area.

Those are the coldest in the records I have, for what it is worth

I think I am so biased because 2021 and 2022 were so much more drastic in heat for my area. 2022 would have been drier if not for the really wet spring.

This summer was notable in this area for consistent warmth but not much in the way of extreme heat.    North Bend has a peak average high in the summer of 79 but we had 66 days at 80+ this year.   

Also in terms of consistent warmth... SEA had the second longest streak of 70+ days just falling short of the record from 2018.

I understand that the sound has been way warmer than me. For my small sample size the extremes in the shoulders came late and then fast. It gave the illusion that this year has been cold. My pool never hit higher than 77 this year. Last year it hit 85. 2021 it hit 89. 

[Cascadia_Wx]

61/53 day here. On the cool and cloudy side with some showers at times. Looking forward to another 4-5 days of pleasantness before we go back to

Was July and August of 2021 warm there?    July and August this year were actually warmer than July and August of 2021 at SEA.

80's get as far north as Bremerton on the 12Z Euro.

October.  

[TT-SEA]

00Z GFS turns wet right around day 10.   00Z GEM still has the ridge holding on at that time.   As @ShawniganLake mentioned... the upcoming ridging period will likely end with some type of AR action whenever that happens.

 

[SilverFallsAndrew]

70s in early October is nothing to write home about.

Honestly your posts tonight are pretty close to falling into the trolling category. At best none of this makes any sense.

Should be of the warm, pineapple express variety. Pure niño.

Average high of 79. That’s closer to our average low these days.

[Phil]

Can see the transient period of subsidence east of the dateline associated with the cycle of ridging upcoming.

Opposes the niño circulation so likely won’t last long. Can also see the CCKW/MJO thru which it manifests.

[Phil]

And remember the teleconnection w/ PNW climo reverses come D/J/F. P8 RMM/LP is a cool and/or stormy signal during autumn but full blown ridgy come January.

And Vice versa for higher frequency bouts of Pacific subsidence like this one. Currently it’s a warm signal, come January it’s a cool/wet signal. Statistically speaking, in this case.

Big change from yesterday when a typical October warm spell was the immoral destruction of our entire ecosystem.   Troll much?

Yep, But its been clear here all night. Just some ground fog

[GHweatherChris]

33 and frosty here this morning, this is the first time I have seen frost in September out this way, at least I don't remember it happening any other time.

[ShawniganLake]

39 here with a very light frost on some surfaces.  

[Ellsworb]

46 and overcast skies on the east shore of lake tapps.  The lake always keeps us just a few degrees warmer than stations just 1/8 sm away. . .reporting 43 and 44 right now respectively.

Temperature doesn’t tell the whole story for agriculture.  You should calculate the growing degree days for those years and get back to us. 

[Rubus Leucodermis]

43.0˚F. Broke down and turned on the heat.

[MossMan]

Haven’t hit the 30’s yet during this arctic blast. 

41 for a low.

There’s a good chance that it could’ve happened in late September/early October 2019. There was some record setting cold that year. Bad sign for winter! 

[TacomaWx]

Got down to 47 here this morning. Coldest low so far this fall was 44 a couple weeks ago. 

[ChrisEl Elyon]

48° here at Eastside Tacoma this morning should be cooler tonight into tomorrow morning

Looked like my first frost that year was on 10/9

At least according to my 40,000 picture archive on my phone.

It got chilly then but no frost until sometime in October.

That is surprising. We had our first frost here on 10/1 with a low of 36. We had our first freeze on 10/10 that year very early for this area.

Ah that makes sense then.
