Seattle is in for a genuinely sunny Sunday, with highs near 78°F, light northwest wind at 2 to 6 mph, and next to no chance of rain — a great day to get outside before the evening cool-down, whether that’s a walk around Green Lake or first pitch at T-Mobile Park.
Today’s Setup
The National Weather Service in Seattle notes that zonal flow aloft combined with increasing onshore flow is keeping today’s high near seasonal normals, with HeatRisk staying in the Minor/Yellow category — comfortable, not oppressive. Forecasters are also watching marine stratus pushing inland along both the north and south Puget Sound corridors overnight, similar to recent mornings, though its eastward progress has stalled for now.
Best Window To Be Outside
Midday through late afternoon is the sweet spot, with sunny skies holding through the afternoon before temperatures ease back toward the upper 50s tonight. If you’re headed to Alki Beach, Discovery Park, or Green Lake, get there before evening, since the marine layer tends to sneak back in overnight and into early Monday.
Gamedays: Mariners, Reign FC, and Live Music
It’s a packed Sunday around town. The Seattle Mariners host the Tampa Bay Rays today at T-Mobile Park, and with sunny skies and light wind, it’s about as good as gameday weather gets — grab official team gear on Fanatics or Find tickets on StubHub if you’re headed down. Seattle Reign FC also plays Angel City FC today at Lumen Field, another solid outdoor-weather match, with Get tickets on SeatGeek an easy option. Music fans can catch Sarah McLachlan’s Better Broken Tour tonight at Chateau Ste Michelle Winery, an outdoor venue that should stay comfortable through the evening. And if you’re planning ahead, the Seattle Storm face the Chicago Sky Monday night at Climate Pledge Arena — indoors, so weather’s a non-issue there.
What To Wear Or Bring
Sun exposure is the main thing to plan for today — a UPF 50+ Sun Hoodie is a smart, breathable layer for anyone out on the water or at the ballpark for hours (check out this UPF 50+ Sun Hoodie deal). Boaters heading onto Puget Sound or Lake Washington should make sure everyone’s covered — West Marine ski vests are worth stocking up on for the season. Bring a light layer for after sunset, since temps drop back to around 58°F overnight.
Dinner Idea
With a warm, dry evening like this, something easy and flexible — pasta or a quick stir-fry — fits the bill without heating up the kitchen too much. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door, and Amazon Fresh groceries makes restocking the pantry simple before the work week.
Next Few Days
Monday and Tuesday look like repeats of today — sunny to mostly sunny with highs near 78°F. The NWS’s longer-range outlook is less certain: models are hinting at an upper-level trough dipping down from British Columbia as early as Tuesday night or Wednesday morning, but forecasters are still waiting for that solution to show up consistently before trusting it. For now, the rest of the week should stay generally dry around the Sound.
