Seattle, Washington – Above-average temperatures are expected across Washington from August 5–9, bringing a prolonged stretch of summer warmth while precipitation remains below seasonal averages. The warmer and drier pattern is expected to increase wildfire concerns across portions of the state while limiting opportunities for meaningful rainfall.
According to the Climate Prediction Center’s 6–10 Day Outlook issued July 30, Washington is favored to experience above-normal temperatures along with below-normal precipitation throughout the outlook period. The climate signal supports persistent warmth and generally dry weather across both western and eastern Washington.
Seattle and Spokane are expected to see temperatures climb above early August averages, while communities including Tacoma, Olympia, Everett, Yakima, Wenatchee, the Tri-Cities, and Bellingham should experience warm afternoons with abundant sunshine and limited opportunities for rainfall. Dry conditions will be most pronounced east of the Cascades, where vegetation will continue to dry and wildfire danger may increase. Travelers should also remain alert for localized smoke that could reduce visibility along Interstate 5, Interstate 90, U.S. Highway 2, and State Route 97 if fires develop or expand.
The combination of above-average temperatures and below-normal precipitation will continue drying grasses, forests, and brush across much of the Evergreen State. Residents should follow local burn restrictions, avoid activities that could spark wildfires, stay hydrated during the warmest part of the day, and monitor local air quality if smoke becomes an issue.
The overall pattern favors continued above-average warmth and below-normal precipitation through August 9, with little indication of widespread rainfall returning to Washington. 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.
