Portland is waking up to one of the nicest late-May Sundays in recent memory — sunny skies, a high near 73°F, and zero chance of rain. Check your Portland weather forecast and make outdoor plans now, because the heat ramps up fast from here.
Today’s Setup
High pressure locked over the northeast Pacific is giving us a clean, unambiguous spring day. The National Weather Service calls for full sunshine through sunset with a high near 73°F. Northwest winds will run 2–10 mph with gusts near 21 mph this afternoon — breezy but totally manageable. If you’re heading to the coast, expect stronger gusts of 25–30 mph thanks to a weak mesoscale low developing along the shoreline this morning. Inland Portland stays in the 20–25 mph gust range.
Best Window To Be Outside
Honestly, the whole day is yours. Morning temps start in the upper 40s and climb steadily to that gorgeous 73°F afternoon peak. Tom McCall Waterfront Park, the Eastbank Esplanade, and the Wildwood Trail in Forest Park will all be prime today.
And if baseball is your thing: the Oregon Ducks Baseball team hosts the NCAA Baseball Regional at PK Park today, May 31 — perfect game-day weather. Snag some Official team gear on Fanatics before you go, or Find tickets on StubHub if you still need seats.
Allergy Alert
Sunny + breezy + late May in the Willamette Valley is peak pollen season. Grass and tree pollen scatter fast on days like today. Before heading out, pop a Claritin non-drowsy allergy tablet, toss some allergy relief nasal spray in your bag, or wear a pollen count face mask on longer trail runs. When you get home, a HEPA air purifier running in the main living area can make a real difference for indoor air quality.
Heat Risk Building Monday and Tuesday
Today’s 73°F is the calm before the warm. The National Weather Service has issued a Moderate HeatRisk for the Portland/Vancouver Metro and Lower I-5 Corridor on Monday and Tuesday. Monday climbs to near 85°F — with roughly a 10% chance of hitting 88°F or higher in the hottest spots — driven by easterly flow aloft compressing and warming the lowlands. Plan yard work and outdoor errands for Monday morning before it heats up.
Upcoming Events Worth Planning Around
Bob Dylan w/ Lucinda Williams plays the outdoor McMenamins Historic Edgefield Manor on June 4 — weather looks favorable that far out, but keep an eye on the extended forecast. Grab a Bob Dylan t-shirt and Find tickets on StubHub before they sell out. Also outdoors on June 4: Lord Huron at Hayden Homes Amphitheater. Both shows reward early ticket buyers.
Dinner Tonight
A sunny 73°F afternoon is made for backyard grilling. Fire up a portable propane grill for burgers or tri-tip — and if you want to go next-level, our guide on smoking tri-tip like brisket is worth a read. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
- Monday: Sunny, high near 85°F. Moderate HeatRisk begins for the metro.
- Tuesday: Warming continues — likely the hottest day of the stretch.
- Wednesday–Friday: A low pressure system fills in near the coast; zonal flow returns with clouds possible.
- Next Weekend: Rain chances increase as low pressure intensifies — classic June pattern.
Make the most of today. Portland doesn’t hand out many afternoons this clean.
