Seattle weather today is sunny and near 80°F—one of the nicest days we’ve had in a while, so get outside and enjoy it while you can.
The National Weather Service forecasts mostly clear skies overnight through early morning, with temperatures around 55°F and light northeast winds around 3 mph. By Monday morning, an upper-level ridge will keep conditions dry as onshore flow develops. Highs will reach near 80°F in the Puget Sound basin and interior valleys, though the marine layer will keep coastal areas cooler—expect mid to upper 60s along the beaches and around Grays Harbor.
This is an ideal day for the Seattle Mariners vs. Atlanta Braves at T-Mobile Park on Tuesday, May 5th—though today’s warmth won’t last quite as long. If you’re heading to the ballpark, grab a Seattle Mariners jersey or Seattle Mariners fitted cap to show your support, and snag tickets on SeatGeek or Find tickets on StubHub while they’re available. Tuesday’s high will be slightly cooler at 76°F, but still sunny and pleasant for baseball.
The National Weather Service Area Forecast Discussion notes that onshore flow will peak tonight, with the marine layer pushing into the Puget Sound area by early Tuesday morning. Don’t be surprised if you wake up to some fog near the water—it’ll burn off quickly. By Tuesday afternoon, that weak marine push will retreat back to the coastline, keeping interior temps in the upper 60s to mid 70s.
If you’re planning outdoor activities around Discovery Park, Green Lake, or the Ballard Locks, today and tomorrow are your sweet spot before conditions shift mid-week. Pollen counts remain moderate, so if you’re sensitive, consider keeping an allergy relief nasal spray or pollen count face mask handy, especially during peak morning hours.
For tonight’s dinner, fire up the grill while you’ve got clear skies—a simple pasta with grilled vegetables or a stir-fry pairs perfectly with this mild weather. You can order groceries on Amazon and have everything delivered in time for dinner prep.
Looking ahead: Wednesday brings little change, with mostly clear skies and lows near 54°F. The pattern holds through Thursday before a dissipating front tries to move in later Friday into Saturday morning. Make the most of this dry stretch—Seattle knows how to appreciate a sunny May day.
