Seattle started Sunday, June 28, 2026, under a stubborn marine layer, with Boeing Field waking up to cloudy skies and temperatures hovering around 55°F this morning. The cloud deck is expected to gradually thin during the afternoon, opening the door for some partly sunny breaks and highs near 70°F while light south‑southwest breezes keep things calm. For most neighborhoods it will feel mild and jacket‑friendly rather than hot, with temperatures sliding back into the mid‑50s tonight.
Afternoon Outlook
The warmest stretch should arrive in the late afternoon, when temperatures climb into the upper‑60s to around 70°F and winds run about 5 to 8 mph from the south‑southwest. Measurable rain is not expected today, with precipitation chances only a few percent, although clouds are likely to hang on into the evening. For hour‑by‑hour details and any late tweaks to the forecast, check the National Weather Service.
Boaters And Ferry Riders
Small craft advisories remain in place for portions of the Strait of Juan de Fuca and nearby coastal waters into Monday morning, June 29, 2026, which means choppy seas and gusty conditions for smaller vessels. A late‑Sunday advisory for parts of the central and eastern Strait is expected from about 5 PM Sunday to 1 AM Monday, while other coastal advisories extend into Monday morning. Ferry riders and mariners should look over current bulletins before heading out; WSDOT ferry alerts cover route‑specific updates, and the National Weather Service marine forecast offers zone‑by‑zone guidance.
What To Expect This Week
An onshore flow pattern will keep things cooler and on the cloudier side through midweek, with afternoon highs generally in the upper‑60s and only isolated, mainly light showers over the mountains. Slight chances for light rain increase late Wednesday night into Thursday, July 1 to 2, although any precipitation looks light and spotty. Forecast guidance leans toward drier, more seasonable weather by late week, and Independence Day on Saturday, July 4, 2026, is currently expected to be mostly sunny with highs near 71°F, so holiday plans should be largely in good shape.
