**Latest National Weather Service forecasts point to a high near 83–85°F for Seattle on August 7, aligning with the market’s leading 84–85°F bin at 36% implied probability.** Persistent above-normal summer conditions across the Pacific Northwest, driven by a broad warm pattern and occasional heat-dome influences, have kept daily maxima elevated. Seattle’s marine west-coast climate typically moderates extremes via onshore flow, yet recent model runs show limited marine intrusion and mostly sunny skies that favor temperatures in the low-to-mid 80s. Historical August averages hover near 76°F, so the current outlook sits several degrees above the long-term baseline. Traders appear to weigh the narrow spread between 82–87°F outcomes most heavily, reflecting model consensus and low expected variability in steering patterns or cloud cover through the 24-hour window. Updated NWS and ensemble guidance remain the key near-term catalysts.
