Portland is serving up one of its finest late-May Saturdays: mostly sunny skies and a high near 79°F, with zero chance of rain. If you’ve been waiting all spring for a day like this in the Rose City, today is your window — check the Portland weather forecast to stay updated through the holiday weekend.
Today’s Setup
High pressure has the Pacific Northwest locked in a warm, dry pattern through Sunday. Inland Portland and the Willamette Valley will respond quickly to sunshine this afternoon, climbing near 79°F with a gentle north-northwest wind of 3 to 8 mph. The National Weather Service cautions that coastal communities will run 15 to 20°F cooler due to persistent marine stratus and ocean upwelling — so if you’re day-tripping to the Oregon Coast, pack an extra layer. The Cascades and Hood foothills land in the mid-60s to mid-70s.
Best Window To Be Outside
The whole day is fair game. Washington Park, the Eastbank Esplanade, and Forest Park trails are all in ideal shape. This is also a great afternoon to hang a hammock with stand in the backyard, get a round of golf in, or break out the corn hole game set for the patio. Sunday looks nearly identical — near 80°F with calm northwest winds. Browse outdoor gear deals if you need anything for the long weekend.
Timbers vs. San Jose — Game Day Forecast
The Portland Timbers host the San Jose Earthquakes today at Providence Park. Expect mid-to-upper 70s at kickoff, light breezes, and perfectly dry skies — about as good as Providence Park weather gets. Represent with a Portland Timbers scarf or Portland Timbers jersey, and if you still need seats, Get tickets on SeatGeek before they’re gone.
Allergy Alert
Warm, dry, and breezy is peak pollen-dispersal weather across the Willamette Valley, where grass pollen runs high through June. If you’re spending the afternoon outside doing yard work or hiking, keep a Zyrtec 24 hour allergy 90 count or allergy relief nasal spray on hand. Back indoors, a HEPA air purifier makes a real difference on high-pollen afternoons.
Sunday Events
Stars on Ice - U.S. skates into Veterans Memorial Coliseum on Sunday — a solid indoor option to cap the holiday weekend. Purity Ring also plays Revolution Hall Sunday night. Find tickets on StubHub for either show, and grab a Stars on Ice - U.S. t-shirt as a keepsake.
Dinner Tonight
A light pasta or fresh stir-fry is a perfect match for a warm, breezy Saturday evening — easy to pull together and even better eaten on the patio. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Memorial Day Outlook
Enjoy the dry stretch while it lasts. The National Weather Service has high confidence that a broad Gulf of Alaska low will push into the region late Sunday night, bringing widespread rain and a notable cool-down on Memorial Day. Expect 0.25 to 1.00 inch of rainfall Monday into Tuesday, with the heaviest totals along the coast, Coast Range, and Cascades. Get your outdoor plans wrapped up this weekend — and have rain pants waterproof ready before Monday morning.
