Seattle is kicking off Saturday with mostly sunny skies and a high near 76°F — a touch cooler than yesterday, but still one of the nicest days of the month to get outside and enjoy it.
Today’s Setup
A weak system tracking north through British Columbia nudged cooler marine air inland overnight, shaving about 7 to 10 degrees off yesterday’s highs, according to the National Weather Service Seattle office. But 76°F with zero rain chance and a light southwest breeze of 5 to 8 mph is classic Pacific Northwest at its best. Overnight lows dip to around 55°F — crack a window and sleep well. Check the Seattle weather forecast to track the week ahead.
Best Window To Be Outside
All of it. Green Lake, Discovery Park, the Burke-Gilman Trail — all fair game from sunrise to sunset. If you’ve been eyeing a backyard upgrade, a patio furniture set stays dry all weekend. It’s also a prime afternoon to break out the Father’s Day grilling set and fire something up before the weekend slips away.
Mariners vs. Red Sox — Sunday at T-Mobile Park
The Seattle Mariners host the Boston Red Sox on Sunday, June 21 at T-Mobile Park, and the forecast is as good as it gets for baseball. Sunday climbs to a sunny near 80°F with light west-northwest winds — tailgating conditions are ideal. Grab a Seattle Mariners jersey or a Seattle Mariners fitted cap to rep the home team in style. If you still need seats, Find tickets on StubHub or Get tickets on SeatGeek.
Upcoming Events Worth Knowing
Wednesday, June 24 brings the Don Toliver: Octane Tour to Climate Pledge Arena — an indoor show, so weather’s no issue. A Don Toliver t-shirt is the right call for the night. Then June 25, the Fuerza Regida: This Is Our Dream Stadium Tour 2026 lands at T-Mobile Park outdoors — the warm trend looks favorable. Neptune Theatre also hosts HONNE’s 10 Year Anniversary Tour on June 22 if you’re looking for something closer to home this weekend.
What To Wear
A T-shirt and light shorts handle the afternoon fine. Bring a light layer for evening — lows drop to the mid-50s and breezes pick up near the Sound. No umbrella needed all weekend.
Dinner Tonight
A warm, breezy evening calls for something easy and fresh. Whip up a quick stir-fry or a herb pasta you can eat on the deck — a live herb plant collection on the windowsill makes this kind of meal way better. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Sunday tops near 80°F. Then Monday heats up significantly — the National Weather Service forecasts 80s to around 90°F in the Southwest Interior lowlands, with Moderate HeatRisk in effect for interior Puget Sound areas. The ridge weakens mid-week, cooling things down, and there’s a chance of the region’s first rain in more than two weeks by late next week. Soak up this sunshine — it’s earned.
