Portland woke up feeling pretty comfortable Monday morning, with clear skies and about 63°F at Portland International Airport. That pleasant start will not last long. Forecasters expect a sharp spike in temperatures this afternoon, with highs headed for the upper 90s and some inland Willamette Valley spots flirting with 100°F by midafternoon. Overnight, the city will get only limited relief in many neighborhoods.
Afternoon Heat And Timing
The National Weather Service has an Extreme Heat Warning in effect through 11 PM PDT Tuesday and is calling for daytime highs near 98°F, with heat index values into the mid 90s for the Portland metro area. Winds should stay generally light out of the north-northwest at about 2 to 9 mph this afternoon, although gusts could reach 20 to 25 mph in parts of the valley and the Columbia River Gorge. Interior Willamette Valley locations have an elevated chance of hitting 100°F, so plan your errands and outdoor time accordingly, according to NWS Portland.
Where To Cool Off
If your home runs hot, Multnomah County and the City of Portland maintain lists of staffed cooling spaces and can open community centers, libraries, and shelters as needed. You can call 211 to find the nearest option and ask about transportation. Locations frequently used during past heat responses include the Portland Building at 1120 SW 5th Ave and Matt Dishman Community Center at 77 NE Knott St, although actual openings depend on staffing and official declarations. For details and resources specifically aimed at older adults, people with medical conditions, and pet owners, head to Multnomah County.
Tonight And The Week Ahead
Monday night stays on the warm side, with lows only dropping into the mid 60s. That will limit overnight cooling for many residents, even as northwest winds bring occasional gusts up to around 20 to 25 mph in some spots. Onshore flow is expected to return Tuesday, which should ease inland highs back into the 80s by midweek. Another warm push later in the week could send some areas toward the upper 80s or near 90°F again by Thursday. No meaningful rain is in the forecast through the weekend, so outdoor event planners and yard work diehards should be ready for hot, dry conditions.
Heat Safety
Health officials and forecasters are pushing the usual but crucial advice: drink plenty of water, avoid heavy exertion during the peak heat window from roughly noon to 7 p.m., and spend time in air conditioned spaces when possible. Check in on neighbors, people with existing health issues, and anyone who might be living alone, and do not forget pets. Never leave children or animals in parked cars, even for a short errand. If you or someone nearby shows signs of heat stroke, such as confusion, fainting, or loss of consciousness, call 911 right away. Employers and outdoor workers should build in frequent rest breaks in shaded or air conditioned areas and make sure water is always available.
