Seattle is starting Saturday near 54 degrees with mostly clear skies, but clouds will build through the day before a slight chance of rain arrives after 5 p.m. The high should reach around 70 degrees, keeping the day comfortable for Labor Day weekend plans even if the sky refuses to fully commit.
Clouds Build Before A Brief Evening Rain Chance
Saturday will trend mostly cloudy, with light north winds generally between 1 and 5 mph. The chance of rain reaches about 20% late in the day, and any new rainfall should stay below a tenth of an inch.
The National Weather Service Seattle forecast also allows for scattered showers and isolated thunderstorms elsewhere across western Washington, particularly near the mountains. For Seattle proper, the forecast points to a much quieter evening, with rain chances fading after 7 p.m. and temperatures settling near 54 degrees overnight.
Sunday And Labor Day Look Better
Sunday should bring mostly sunny skies and a high near 71 degrees, followed by a partly sunny Labor Day with a high around 70. Overnight lows will remain in the mid-50s, so early-morning outdoor plans may still call for a light layer.
That is a modest shift from Friday’s forecast, which leaned drier for Saturday. The latest outlook adds a small late-day rain risk but keeps the broader holiday weekend mild and manageable.
Mild Midweek Before Rain Returns
Tuesday and Wednesday should stay mostly sunny, with highs near 71 and 74 degrees. Thursday remains mostly sunny for much of the day but carries a slight chance of light rain between 11 a.m. and 5 p.m., while Friday turns cooler and cloudier with a chance of rain and a high near 69.
No watches, warnings or advisories are in effect for the Seattle area. The practical weekend forecast is simple: expect a gray Saturday afternoon, a brighter Sunday and a mostly comfortable Labor Day.
