Portland woke to clear skies and temperatures in the mid-50s Monday, but the comfortable start will give way to a hotter, smokier afternoon. The high is expected to reach about 87 degrees, with wildfire smoke arriving after 11 a.m. and north winds increasing through the day.
Smoke Arrives As Afternoon Winds Pick Up
Temperatures should climb quickly through the afternoon, reaching the mid-80s to near 87 degrees before easing slightly in the evening. North winds of 5 to 10 mph may gust as high as 21 mph, while smoke could become more noticeable across the metro area, according to the National Weather Service.
Tonight will remain clear with areas of smoke and a low near 61 degrees. There is no rain in the forecast, and the dry, breezy setup is raising broader fire-weather concerns across parts of the region.
Heat Advisory Starts Tuesday
The bigger heat arrives Tuesday, when Portland is forecast to reach 97 degrees under sunny skies. A Heat Advisory is scheduled from noon Tuesday through 11 p.m. Wednesday, with afternoon highs of 95 to 100 degrees and overnight lows in the low to mid-60s.
Wednesday is expected to be the hottest day of the stretch, with a high near 100 degrees and light north winds. Smoke may limit temperatures by a few degrees in some locations, but the combination of heat and degraded air quality could still create dangerous conditions for people spending extended time outdoors.
Cooler Air Finally Returns This Weekend
Thursday will stay hot near 96 degrees, followed by a more manageable high around 90 Friday. Onshore flow should strengthen late in the week, helping push smoke east and bringing temperatures down to about 83 Saturday and 80 Sunday.
The forecast remains dry through the weekend, so outdoor plans will not face rain delays—but heat and smoke may still affect when and how comfortably people can be outside. The shift is a substantive update from earlier Hoodline coverage of Portland's previous hot spell.
Plan Ahead For Heat And Smoke
Drink plenty of fluids, seek shade or air conditioning during the hottest hours, and check on older neighbors and anyone without reliable cooling. People with breathing problems should limit outdoor exposure if smoke thickens and keep an eye on air-quality updates.
Pets and children should never be left in parked vehicles, even for a short errand. Outdoor work and exercise are safest in the morning or evening while Tuesday and Wednesday's heat is at its peak.
