Seattle weather: Record heat ramping up Sunday

Published June 14, 2026 4:00 AM PDT

Temperatures are heating around western Washington.  Whether you are heading to cool off in area lakes or to enjoy one of the several watch parties around town, be sure to take breaks and stay hydrated.  Also, be safe in the water, as many are still cold even on our hot days.

A heat advisory will go into effect late Sunday morning through early Tuesday morning. While our afternoon days will be hot, with high fire danger, the nights will also be mild, offering little relief to try and cool off. Be sure to take extra care of pets, children and the elderly who might be more susceptible to the heat.
