Portland is looking at a sunny Sunday with a high near 86°F, and the National Weather Service says this is just the first rung on a warming ladder that pushes interior valleys close to 90°F by Monday — so enjoy the relatively comfortable air today before the real heat builds midweek.
Today’s Setup
Clear skies overnight let temperatures dip to a low around 57°F before actually rising back toward 59°F closer to dawn — a telltale sign of the building ridge the NWS Portland office says is centered over the Great Basin and extending into the Pacific Northwest. Sunday brings sunny skies, a high near 86°F, and light north-northwest wind at 5 to 8 mph — calmer than the gusty days the Columbia River Gorge is famous for.
Best Window To Be Outside
Morning through early afternoon is the move. A stroll or run along Tom McCall Waterfront Park or the shaded trails of Forest Park stays comfortable before peak heat settles in during the late afternoon. If you’re headed toward Mt. Hood for cooler air, forecasters note higher terrain is warming efficiently too, into the upper 70s and 80s.
Rain, Wind, Or Heat Risk
No rain in the picture — the forecast shows 0% chance of precipitation today. The NWS discussion is clear that dry weather persists into midweek, with heat impacts becoming a growing concern across the interior lowlands as the ridge strengthens further Monday through Wednesday. Nothing severe is expected today, but it’s worth starting to hydrate and plan shade breaks now.
What To Wear Or Bring
Dress light — bamboo no show socks and breathable layers beat the afternoon warmth. If you’re setting up in a park or backyard, an outdoor yoga mat makes an easy shaded workout, and this is prime season to fire up a portable propane grill for dinner outside.
Games, Shows, And Tickets
Tonight, Hell’s Kitchen (Touring) takes the stage at Keller Auditorium — a good air-conditioned option once the sun starts dropping. Looking ahead, the Portland Timbers host FC Dallas July 22 at Providence Park, and the Portland Fire face the Dallas Wings the same night at Moda Center — both comfortable indoor-adjacent nights given the warm stretch. Grab tickets on SeatGeek or Find tickets on StubHub, and check out Official team gear on Fanatics before kickoff or tip-off.
Tonight’s Dinner
With grilling weather this good, tonight’s a solid night to smoke tri-tip like brisket on the grill, or keep it simple with pasta or stir-fry — both work fine in this dry heat. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Monday turns mostly cloudy with a high near 89°F and only a 1% chance of any stray moisture. The NWS says Monday through Wednesday marks the hottest stretch of the forecast, with confidence high for widespread upper 80s to lower 90s inland as the ridge peaks, before temperatures ease slightly late in the week.
