Seattle is kicking off Wednesday with sunny skies and a high near 72°F — one of the finest late-May days in recent memory. Whether you’re hitting the Burke-Gilman Trail, lounging at Gas Works Park, or finally getting the yard in shape, today is the day to be outside.
Today’s Setup
According to the National Weather Service Seattle office, a weak upper-level ridge is nosing into Western Washington with a deep upper-level low parked far to the south over Oregon. Any morning clouds will burn off by late morning, leaving all-day sunshine. North winds stay light at 0 to 9 mph — barely enough to ruffle a napkin at your picnic table. Overnight lows drop to a comfortable 54°F.
Best Window To Be Outside
All of it — but midday through late afternoon will be warmest near 72°F. This is a prime window for outdoor chores: mowing, gardening, and backyard projects all check out before the pattern changes. Golf fans, conditions don’t get much better than this in the Pacific Northwest — check out the Callaway Big Bertha Fairway Wood deal at $150 before the rainy stretch returns.
Allergy Alert
Low wind and warm sunshine create peak pollen conditions today — grass pollen is especially elevated across the Puget Sound lowlands in late May. Before heading out to the waterfront near Pike Place Market or the Washington Park Arboretum, pack your allergy relief nasal spray. At home, running a HEPA air purifier in your bedroom overnight helps after pollen settles on clothes and hair from a full day outside.
Tonight’s Events
Two solid options this evening. The Seattle Storm host the Washington Mystics at Climate Pledge Arena — indoors, no weather concerns at all. Trey Anastasio also plays An Acoustic Evening with Trey Anastasio at the Paramount Theatre tonight. Get tickets on SeatGeek for either show. Phans heading downtown: a Trey Anastasio t-shirt plus a light jacket is all you need for the walk back on a mild 54°F evening.
Mariners vs. Diamondbacks This Weekend
The Seattle Mariners host the Arizona Diamondbacks at T-Mobile Park on May 29 and May 30. Thursday still looks stellar — near 78°F and sunny — but the National Weather Service expects rain to arrive Thursday night, with a weak upper-level trough lingering over Western Washington into the weekend. Saturday’s game (May 30) may see some shower chances, so keep that in mind for tailgating plans. Gear up now with a Seattle Mariners jersey and a Seattle Mariners fitted cap for the series, and get tickets on SeatGeek before the weekend rush.
Dinner Tonight
A warm evening like this calls for something light — pasta primavera loaded with fresh vegetables, or a quick stir-fry. Nothing heavy when the patio beckons. You can order groceries on Amazon and have everything for tonight’s dinner delivered right to your door.
Next Few Days
Thursday: sunny and near 78°F — the warmest day of the stretch, so make the most of it. Thursday night brings clouds and a 58% chance of light rain as that upper-level low drifts northward. A weak trough then settles over Western Washington Friday into Saturday, keeping conditions unsettled heading into the holiday weekend. Lock in any outdoor plans for Wednesday and Thursday while skies are clear. Stay current with the Seattle weather forecast and check outdoor gear deals before conditions change.
