Portland, OR – Residents in Portland are set to experience a classic stretch of summer sun with temperatures climbing to nearly 90°F by Tuesday, making heat safety a top concern for the week ahead.
According to the National Weather Service, highs will reach 79°F Saturday before rising to 85°F Monday and peaking near 89°F on both Tuesday and Wednesday. Light northwest winds will provide little relief, and overnight lows are expected to hover in the upper 50s to low 60s, offering limited cooling—especially for those without air conditioning.
The hot, dry pattern will impact much of Multnomah, Washington, and Clackamas counties. City parks, area schools, and commuters across the Portland metro are encouraged to limit strenuous activity during peak afternoon heat. Officials recommend staying hydrated, checking on vulnerable neighbors, and using public cooling centers as needed. With calm winds and clear skies, wildfire risk may increase in outlying areas.
This extended sunny period is typical for late July in the Willamette Valley but serves as a reminder of the importance of summer heat safety. TriMet riders and downtown workers should prepare for extra warmth on trains, buses, and city streets.
The heat is expected to last through at least Wednesday, with no significant relief in sight. Additional advisories may be issued if temperatures climb further or if air quality becomes an issue.
