Portland, Oregon – Above-average temperatures are expected across Oregon from August 5–9, bringing a prolonged stretch of summer warmth while precipitation remains below seasonal averages. The hotter and drier pattern is expected to elevate wildfire concerns across much of the state while limiting opportunities for meaningful rainfall.
According to the Climate Prediction Center’s 6–10 Day Outlook issued July 30, Oregon is favored to experience above-normal temperatures along with below-normal precipitation throughout the outlook period. The climate signal supports persistent warmth and predominantly dry weather from the Willamette Valley to central and eastern Oregon.
Portland and Bend are expected to see temperatures climb above early August averages, while communities including Eugene, Salem, Medford, Pendleton, Klamath Falls, Corvallis, and The Dalles should experience hot afternoons with abundant sunshine and very limited rainfall. Dry conditions will be most pronounced across central and eastern Oregon, where vegetation will continue to dry and wildfire danger may increase. Travelers should remain alert for localized smoke that could reduce visibility along Interstates 5, 84, and U.S. Highways 20, 26, and 97 if new fires develop or existing fires expand.
The combination of above-average temperatures and below-normal precipitation will continue drying forests, grasslands, and rangeland across the Beaver State. Residents should follow local burn restrictions, avoid activities that could ignite wildfires, stay hydrated during the hottest part of the day, and monitor local air quality if wildfire smoke becomes a concern.
The overall pattern favors continued above-average warmth and below-normal precipitation through August 9, with little indication of widespread rainfall returning to Oregon. Additional outlooks from the National Weather Service will provide greater detail on heat trends, fire weather concerns, and any localized changes to the pattern as the period approaches.
