Official National Weather Service observations at Seattle-Tacoma International Airport recorded a maximum temperature of 80–81°F on August 4, 2026, aligning precisely with the market's near-certain outcome. Pre-event model consensus from the National Weather Service anticipated highs near 82°F under sunny skies, light northerly flow, and patchy wildfire smoke that suppressed insolation and limited afternoon warming. This outcome falls within typical early-August climatology for the region, where marine influence and onshore flow often cap temperatures below inland peaks. Revised forecasts incorporating real-time smoke and boundary-layer conditions shifted expectations downward slightly from initial guidance. Only an erroneous station reading, unrepresentative microclimate data, or reanalysis revision could alter resolution, though such discrepancies remain rare for this primary reporting site.
