Portland, Oregon – Portland residents are bracing for a week of unseasonably high temperatures, as thermometers soar to 91°F by Tuesday and Friday, with little relief from the sun in sight.
According to the National Weather Service at Portland International Airport, the metro area will remain sunny with highs near or above 90°F through Friday. Nighttime lows will hover in the low 60s, providing only slight cooling after sunset. Forecasters warn that dry, warm air combined with light north-northwest winds could elevate fire risk in Multnomah and surrounding counties.
Sunny, cloudless days are expected across Portland, Gresham, Beaverton, and Vancouver, WA, with highs peaking Tuesday and again Friday. The brief break comes Wednesday when partly sunny skies and a high near 79°F bring a touch of relief before the heat returns Thursday. Authorities urge residents to avoid strenuous outdoor activity during peak afternoon hours, stay hydrated, and check on neighbors without air conditioning. Those traveling along I-5 or I-84 should prepare for heat-related vehicle issues and carry extra water.
This extended stretch of summer warmth is notable for early July, with temperatures trending 5–8 degrees above average. The National Weather Service advises that additional advisories could be issued if conditions persist.
