Seattle is starting Wednesday, June 17 under a familiar marine layer, but don’t let it slow your morning — the National Weather Service says those clouds will clear by 10 AM PT, leaving mostly sunny skies and a high near 75°F with calm northwest winds of 2 to 7 mph. Get outside and enjoy one of those rare, clean Pacific Northwest summer days.
Today’s Setup
Overnight onshore flow pushed stratus across the metro, keeping early temps in the low 50s. NWS forecasters say that marine air weakens through the morning, with clouds dissipating by mid-morning and sunshine taking over for the rest of the day. By afternoon, spots like Green Lake, Alki Beach, and the Burke-Gilman Trail will be warm and comfortable in the mid-70s. Tonight drops to around 56°F under mostly clear skies — open the windows.
Best Window To Be Outside
Anywhere from 10 AM through sunset is fair game. Low-level onshore flow diminishes through the afternoon, making conditions progressively calmer. Discovery Park, Myrtle Edwards, a paddleboard on Lake Union — all excellent choices. If you’re setting up a longer outdoor spread at a park, a pop-up canopy tent with weights is smart insurance against any lingering breeze. And if the sunny forecast has you eyeing Lake Washington, our pick for the 2-Person Intex Floating Lounge with Cooler for $24 is a steal for the season.
Rain, Wind, Or Heat Risk
None today. Zero percent precipitation chance, no heat advisory, and winds top out at 7 mph. The WPC and SPC have no warnings for the Seattle area — the severe weather is all in the Midwest and South today. This is as clean a forecast as Seattle gets.
