Forecast models and National Weather Service guidance converge on a high in the low-to-mid 80s°F for Seattle on August 25 under mostly sunny skies with light southwest flow. Upper-level ridging has sustained warmer conditions, producing afternoon readings that have already approached or reached the mid-80s at area stations. This supports the overwhelming market consensus on the 84-85°F bin. Outliers remain possible if onshore marine push accelerates or if official thermometer readings at Sea-Tac or Boeing Field register one degree lower due to microclimate effects or measurement timing, though current observations and short-range guidance make such shifts unlikely before sunset.
