Seattle woke up under clear skies Thursday, with Boeing Field starting near 48°F and barely a whisper of north-northeast wind. The stage is set for a dry, mostly sunny day and an afternoon high near 71°F, likely the warmest day of the week. With no measurable rain in the forecast, outdoor plans are looking safe right through the evening.
Afternoon And Tonight
The National Weather Service expects light north winds around 2–7 mph through the afternoon while skies stay mostly clear into the early evening. Tonight brings partly cloudy conditions, lows near 50°F, and only a tiny chance of any showers. For hourly forecast tweaks and the latest marine advisories, check NWS Seattle.
Boaters And Water Safety
A Small Craft Advisory is in effect from 5 PM Thursday through the overnight hours for the Strait of Juan de Fuca and nearby central waters, so small boats and kayaks should be ready for choppier seas and a stronger onshore push this evening. Puget Sound is still running around 50°F at the surface, which means a surprise dunk can trigger cold shock even on a warm, sunny day. Wear a life jacket and have a solid plan for getting out of the water fast. Ferries and larger vessels will keep moving, but recreational outings after sunset deserve an extra careful look.
Weekend Outlook And Heat Risk
High pressure rebuilds over the weekend and nudges inland temperatures into the upper 70s and low 80s in some valley and foothill spots on Sunday and Monday. That setup brings a Minor HeatRisk through Saturday and a Moderate HeatRisk on Sunday for people who are especially sensitive to heat, so it is wise to dial back strenuous outdoor activity during the hottest part of the day.

Plan Ahead
Friday may come off a bit cooler and cloudier as a weak front nudges more clouds over the region, but the warm and dry pattern bounces back for the weekend, so think morning workouts and shaded meetups if you are planning to be outside.

Keep an eye on short-term updates if you are lining up boating trips or outdoor events after sunset.
