Portlanders eased into Monday with mostly clear skies and mild morning temps, but the cooldown will not last. The interior lowlands are on a fast track to a serious warm-up, with today expected to top out near 89°F before the real heat shows up Tuesday and Wednesday.
Afternoon Sizzle And Coastal Relief
Inland neighborhoods should brace for a quick climb, with highs near 96°F on Tuesday and roughly 97°F on Wednesday. Along the coast, it is a different story, where lingering marine influence keeps things in the 60s to 70s. Winds will stay light and generally from the north or northwest, which could limit overnight cooling in some spots.
If you are planning afternoon errands or workouts in East Portland or Gorge-facing neighborhoods, this is the time to reshuffle the schedule. Early morning or evening hours will be far more comfortable, and your future, less-overheated self will thank you.
Heat Advisory And Safety
The National Weather Service has issued a Heat Advisory for the Portland metro and nearby valleys from 10 a.m. Tuesday through 11 p.m. Wednesday, warning of widespread temperatures between 95°F and 98°F and an elevated risk of heat-related illness, according to NWS Portland. The agency is urging people to drink plenty of fluids, skip strenuous outdoor work during the hottest hours, and check on neighbors and vulnerable residents.
The City of Portland and Multnomah County maintain lists of cooling spaces, and TriMet will not turn away riders traveling to cooling centers, per Portland's heat resources.
Plan Ahead
Try to stack outdoor chores, dog walks, and workouts in the early morning or after sunset, when temperatures are less punishing. Make sure kids and pets have water and shade during peak heat, and do not leave anyone in a parked car, even for a short stop.
Watch for signs of heat exhaustion such as heavy sweating, weakness, headache, or dizziness. Move anyone with these symptoms into shade or air conditioning and call 911 if they become confused or lose consciousness.
Updates
Keep an eye on National Weather Service forecasts and local emergency pages for any changes to advisories or cooling center hours. Employers and schools may also adjust schedules if the advisory is extended. This story will be updated if conditions or warnings change.
