Seattle, WA – Summer heat isn’t letting go just yet, with another round of mid-80s temperatures arriving Wednesday before a shift ahead of Labor Day weekend. The National Weather Service continues its Heat Advisory through Tuesday evening, warning residents to take precautions as daytime highs stay well above seasonal norms.
According to the National Weather Service in Seattle, Wednesday will bring mostly sunny skies and a high near 83°F, with winds shifting southwest around 6 mph. Afternoon outdoor activities could become uncomfortable, especially for those without shade or cooling access. Hydration and limited time in direct sun are urged, particularly for children, seniors, and outdoor workers.
King County officials caution drivers along I-5 and I-90 that heat can strain vehicles and increase tire blowout risks. Checking fluids and tire pressure before long drives remains essential. Public transit stations may also feel warmer than usual, with heat lingering in concrete-heavy corridors.
The warmth sticks around Thursday with highs again in the low-to-mid 80s before clouds and cooler air move in Friday. Temperatures will fall into the upper 70s this weekend, offering some relief just in time for holiday travel. Sunday and Labor Day look seasonable and more comfortable, setting up good conditions for outdoor plans.
Seattle residents should prepare for another warm midweek stretch while planning ahead for cooler, milder conditions by the holiday. Weather alerts remain in effect through Tuesday evening, with no additional advisories yet posted for later in the week.
