Seattle is waking up Monday around 57 degrees under mostly clear skies, but the week is about to make a sharp turn warmer. Sunshine will carry the city to about 76 Monday, with Tuesday expected to be the hottest day near 86 before cooler conditions and a late-week rain chance move in.
The National Weather Service Seattle forecast calls for north winds of 6 to 10 mph Monday, with any morning marine layer clearing quickly. Tuesday should stay mostly sunny with lighter winds, though forecasters say moderate heat risk will return to the Seattle metro and some regional wildfire smoke could bring periods of haze.
Tuesday Brings The Week’s Peak Heat
Tuesday night should remain mostly clear with a low near 59, followed by a more comfortable Wednesday near 77. Thursday cools further to around 73 under partly sunny skies, with overnight lows mostly in the mid to upper 50s.
Rain Chances Arrive Friday
Friday starts partly sunny and reaches about 71, but a chance of light rain develops after 5 p.m. The rain chance continues Friday night and Saturday, when Seattle could top out near 69, before Sunday turns mostly sunny again near 69.
Monday and Tuesday offer the clearest window for outdoor plans, while late-week events may need a rain backup. The City of Seattle recommends drinking water, moving strenuous activity away from the hottest part of the day, and using air-conditioned public spaces if needed.
