Seattle Halloween Outlook: Start waterproofing the costumes now…

A girl dressed as the Stanley Cup tries trick-or-treating in the pouring rain in Snohomish County on Oct. 31, 2024.
What an active weather weekend with three storms in rapid succession bringing weather we hadn’t seen in a while.
To wit:
* Friday’s 1.04” of rain in Seattle was the wettest day in Seattle since Dec. 5, 2023.
* Saturday’s 56 mph gust was the windiest day in Seattle since Dec. 18, 2024
* Sunday’s high of 50 was the coldest day in Seattle since March 20, 2025.
Feel like we need a break? As luck would have it, we’ll get one… for all of about 36 hours. Monday will be mostly dry though we still can’t rule out a few still lingering showers from the weekend mayhem.
Another “storm” comes in during later Tuesday — if this past weekend weather was a bear, this midweek storm is a cub. Just some light rain that will begin around Tuesday afternoon or evening with gentle rains through the night and into Wednesday morning then tapering to showers.
Thursday is another break and yeah, if you’re scoring at home (let me know because it’d be fun to generate some sort of game score around this) that would be four days with no real weather headlines, just a period of some light Seattle rain mixed in there.
SO THAT HAS TO BODE WELL FOR HALLOWEEN, RIGHT?
RIGHT?
Ummm….
I know it poured rain on last year’s Halloween and two of the last three so you’d think we’re due for one where kids don’t have to be like: “But Moooooooom, I was the GoreTex Monster LAST year….”
Maybe this year you can be a Gortex Dragon!
The long range forecast models have been pretty consistent about a potential atmospheric river again on Friday and that is still holding true even as the day draws closer.
There’s some minor disagreements in the various models on whether the rain will only fall on Friday or if it’ll stall and the rain goes well into Saturday but most scenarios right now are pretty wet Friday evening either way. The Euro model is painting about a third to half inch of rain in the core Seattle/Puget Sound Metro area in just 6 hour period from 2-8 p.m.
Minor saving grace is it doesn’t look too windy, just wet. We’ll cross fingers that the storm either speeds up or slows down.
Saturday also looks wet, then maybe a break on Sunday— a Sunday don’t forget we get an extra hour to enjoy as Daylight Saving Time ends.
(Also before the grammar folks chime in, I know daylight saving time is supposed to be lowercase but I’ve always thought that looks funny and seems like a proper title, so after years of having to lower-case it for my media “day job”, it’s my blog page and so I’m GOING ROGUE! MAYBE LATER THIS WEEK I’LL EVEN CALL IT “DAYLIGHT SAVINGS TIME”. I’M SO FREE!!!
(And now my family is wondering: “Why is Daddy making evil cackling sounds at his laptop?”)
The long range forecasts are still trending occasionally wet and stormy into the following week. But at least the sun will start setting at like 5 p.m. so you won’t be missing anything.
