Seattle woke up to clear skies Friday, May 22, with Boeing Field (KBFI) starting the morning at about 54°F. The sun will stick around through the afternoon, pushing most inland neighborhoods into the low to mid 70s, with a high near 74°F expected. Light northwest breezes will keep shoreline spots a few degrees cooler, but this dry setup is not sticking around for the holiday weekend.
Afternoon Sun, Light Northwest Breeze
Expect mostly sunny skies and gentle north–northwest winds around 1–6 mph through the afternoon. Interior areas will run warmest while the marine layer keeps shoreline temperatures in check. Temperatures should peak in the low to mid 70s by late afternoon before skies stay mostly clear into the evening.
Memorial Day Rain and Marine Alerts
Late Sunday night brings the first chance of rain, and rain is likely on Memorial Day, Monday, May 25, with highs near 60°F, according to the National Weather Service Seattle. Forecasters are estimating about a quarter to three‑tenths of an inch of rain in the lowlands and roughly 1 to 1.5 inches in the Cascades and Olympics from Sunday afternoon through Tuesday afternoon. Small Craft Advisories are in effect for parts of the Strait and coastal waters through this morning, and the discussion warns of choppy seas and the potential for localized gale‑force gusts through the Strait Saturday night, with gusts around 25 knots (about 29 mph) and probabilities peaking near 75% in some areas, so mariners should plan accordingly.
Plan Ahead
Make the most of Friday and Saturday for outdoor plans, and bring layers for cool mornings. If you're headed out on the water or relying on ferries, secure loose gear, expect some delays during choppy conditions, and check updated forecasts, and see how the timing has shifted for this week.
