Portlanders woke up to clear skies and a gentle start Tuesday, July 14, 2026, but inland neighborhoods are on track to roast in the upper 80s and low 90s by afternoon. Sunshine rules across the metro, with the warmest spots away from the river and the coolest air hanging out along the coast.
Hot Inland, Chill by the Coast
Interior lowlands are expected to top out near 90°F later today, while the coast stays a good deal cooler in the mid to upper 60s. Light north-northwest breezes, generally 1 to 5 mph inland, will let heat pool in areas exposed to the Columbia Gorge and Willamette Valley, so those spots will feel the toasty side of the forecast. If you can, aim outdoor work or workouts for the morning or evening rather than the peak afternoon hours.
Late Wednesday Rain Chance and a Heads-Up for Mariners
According to NWS Portland, rain is likely late Wednesday night into Thursday morning, generally after 11 p.m. on Wednesday, July 15, 2026, with about a 60% chance and mostly light totals expected. Forecasters note that timing and coverage could still shift. If the approaching low comes onshore earlier than projected, areas north of Salem and parts of southwest Washington could pick up heavier, localized downpours.
Out on the water, a Small Craft Advisory is in effect for the Columbia River Bar through 9 a.m. Tuesday, July 14, 2026, with another advisory anticipated during the early Wednesday morning ebb. Mariners are urged to check local marine forecasts before heading out.
Cooling Centers, Transit Help and Staying Safe
Multnomah County has opened daytime cooling centers and is listing libraries and community centers as cool spaces for people without reliable air conditioning, according to Multnomah County. The county notes that TriMet will not turn away riders traveling to cooling centers during heat response periods, and that 2-1-1 can connect people with nearby cool locations and transportation assistance.
Hydrate often, avoid strenuous outdoor work during the hottest part of the afternoon, and keep a close eye on the forecast if you have early morning boating plans or late-night events from Wednesday into Thursday. For the latest details, check the National Weather Service and county pages before you head out.
