Seattle woke up Friday to one of those classic, get-outside-now mornings: clear skies, mild air and about 54°F at Boeing Field with a light north wind. Forecasters expect a mostly sunny day with a high near 70°F and only a slight chance of a stray sprinkle inland this afternoon.
Afternoon And Weekend Outlook
Highs should land near 70°F Friday and again Saturday, before a stronger warm-up pushes inland temperatures into the 70s and low 80s on Sunday. A forecast high near 81°F for Seattle would break the daily record of 77°F. The warmest air is expected Sunday as low-level flow briefly turns offshore, while outer coastal waters stay under a Small Craft Advisory through 11 PM tonight, according to the National Weather Service. April ran drier than normal, with Seattle picking up about 2.77 inches of rain and only eight days with measurable precipitation, so the upcoming sun and warmth may feel especially intense.
What This Means For Your Plans
Sunday is on track to be the warmest day of the year so far for many neighborhoods. Parks, patios and inland hills east of the Sound should see the highest readings, while waterfront spots stay a bit cooler. If you are heading outside, consider shifting your heaviest activity to the morning or evening, keep water and sunscreen handy, and check in on pets and older neighbors during the peak afternoon heat.

Timing And Temperatures
Temperatures climb into the upper 60s by late morning and reach around 70°F by mid-afternoon Friday, with light north-northwest winds of 2 to 8 mph. Friday night will cool into the low 50s. Sunday afternoon is expected to be mostly clear with inland highs in the upper 70s to low 80s, before cooler air moves back in Monday as onshore flow returns.
Quick Tips
Coastal boaters should heed the Small Craft Advisory for exposed offshore waters, and there are no land watches or warnings in effect for King County at this time. Enjoy the early taste of summer, but check conditions before heading out on Puget Sound or planning long, strenuous outdoor activities on Sunday.
