Seattle is waking to clear skies and temperatures around 55 degrees Monday morning, with the thermometer headed for a mild afternoon high near 75. North winds will build to 10 mph later in the day, but rain is nowhere on the Monday forecast. The bigger shift arrives this week, as temperatures climb toward the upper 80s.
Warm-Up Peaks Near 90 Degrees
Tuesday should reach 83 degrees, followed by 86 on Wednesday and 88 on Thursday, according to the National Weather Service Seattle office. Friday cools to about 82, with the weekend easing further into the upper 70s and mid-70s.
Wildfire Smoke Could Become More Noticeable
The forecast discussion warns that elevated wildfire smoke may increase over Western Washington Monday before becoming more surface-based Tuesday. Low-level northerly flow could pull smoke from fires in Eastern Washington into the region, so hazier skies and less comfortable air are possible as the heat builds.
Dry Weather Favors Outdoor Plans
Rain chances remain at zero through Saturday, with only a 1% chance of precipitation Sunday. Overnight lows stay mostly in the upper 50s and lower 60s, offering some relief after the warmer afternoons.
With low humidity expected Tuesday through Thursday, especially Wednesday and Thursday, residents should be cautious with outdoor flames and stay hydrated during strenuous activities. Seattle’s heat-safety guidance recommends moving demanding outdoor activity to cooler parts of the day and checking on people who may be more vulnerable to heat.
