Seattle woke to low clouds and cool readings on Friday, July 24, 2026, with Boeing Field checking in around 62°F under overcast skies early this morning. The gray start will not last long. A quick warm up is on tap this afternoon, with inland neighborhoods expected to top out in the low 80s while waterfront spots hang back in the low to mid 60s. Southwest breezes stay on the lighter side today, and the marine layer should pull back toward the coast by late afternoon.
Afternoon Warmth, Then a Cooler Weekend
A brief ridge will nudge highs up near 83°F today (Friday, July 24), but that warm bump is short lived. An upper level trough is expected to move inland on Saturday, trimming daytime highs into the low 70s and bringing spotty showers through Sunday. If you have outdoor plans this weekend, count on cooler, more changeable weather compared with today’s sunshine. Forecasters at NWS Seattle note that the trough will likely hang around into early next week.
Boaters Watch the Strait
Small Craft Advisories are in effect for parts of the Strait of Juan de Fuca this morning and again tonight into Saturday, with choppy seas and stronger south southwest winds expected. Mariners should secure loose gear and avoid the more exposed crossings during advisory windows. Onshore flow will pick up Saturday, bringing breezier conditions, with south southwest winds around 8 to 12 mph in the afternoon and evening. For the full marine picture, check the forecast from NWS Seattle.
Foggy Mornings, Sunny Afternoons
Low clouds and MVFR conditions will linger across the lowlands this morning, so giving yourself extra time for early commutes and flights is not a bad idea. Most interior spots should improve to VFR by mid to late morning. Plan on the classic Seattle layering routine: cool, breezy mornings near the water, followed by reliably sunnier afternoons inland. For weekend events, keep a light jacket handy near the shoreline and expect a slight chance of showers both Saturday and Sunday.
