By 5:30 a.m. PDT Saturday, April 4, 2026, Seattle was already waking up under mostly clear skies, with temperatures in the low 40s at Boeing Field. Forecasters are calling for sunshine through the afternoon, a high near 61°F, and generally light north winds, setting up a solid window for outdoor plans. Patchy fog and pockets of chill in low-lying spots are expected to burn off quickly after sunrise.
Morning Into Afternoon
Morning frost advisories for nearby interior valleys expired at 9 a.m., and any lingering patchy fog should dissipate soon after. The forecast calls for a high near 61°F this afternoon, with north winds around 2 to 9 mph and mostly sunny skies. VFR flight conditions are expected at KSEA through the day, according to the National Weather Service.
Afternoon Winds And Commute
Winds will stay light across most neighborhoods, while exposed hilltops and shorelines could see gusts near 10 mph late in the afternoon. Road surfaces should dry by midday, and routine weekend transit service is not expected to be affected. For background on the pattern shift that cleared out the rain and opened the door to this warm weekend, see our earlier forecast on the recent rain Thursday, warm weekend ahead.
Weekend Outlook
A ridge of high pressure should keep Monday on the mild side, with highs climbing into the mid to upper 60s before a marine push Monday night into Tuesday knocks daytime temperatures back to the low to mid 50s. Mariners and shoreline planners should keep an eye on an onshore return and building seas early next week, with forecasters noting a possible stronger westerly push Monday night into Tuesday. Overnight lows are expected to hold in the 40s through the weekend, so a light jacket will still come in handy for evening plans.
