Seattle was starting Sunday under clear skies near 57 degrees at Boeing Field, with no wind to speak of. The city should warm into the low 70s under mostly sunny skies, with little chance of rain to interfere with Labor Day weekend plans.
Sunny Sunday Gives Way To A Cloudier Monday
Sunday’s high is expected to reach about 72 degrees, with light north winds generally between 2 and 6 mph. The latest outlook is a modest update from Saturday’s forecast, nudging the afternoon temperature slightly higher while keeping the weekend largely dry.
Labor Day should be cooler and cloudier, with a high near 70 and a small chance of rain. Onshore flow could bring a gray start or a little drizzle Monday morning before clouds break for occasional afternoon sun.
Warmer Weather Arrives Before Rain Chances Return
Tuesday should turn mostly sunny near 72 degrees, followed by the warmest day of the stretch Wednesday, when Seattle could reach about 75 under sunny skies. Thursday stays mostly sunny with a high near 73, making the middle of the week the best bet for easy outdoor plans.
The pattern shifts slightly Friday, with partly sunny skies, a high near 70 and a slight chance of light rain after 5 p.m. Saturday currently looks brighter again, with mostly sunny skies and a high near 72.
Small Craft Advisory Covers Strait Waters
Seattle proper has no land-based watches or warnings, but boaters should note a Small Craft Advisory for the central and eastern Strait of Juan de Fuca from 5 p.m. Sunday through 5 a.m. Monday. The National Weather Service expects stronger westerly winds in the strait during that period.
