Latest National Weather Service guidance points to a high near 72°F on August 2 as moderating onshore flow and increasing cloud cover limit daytime heating, positioning the 70–73°F range as the clear market leader. Seattle’s marine climate, driven by cool Pacific air and typical August afternoon marine-layer development, supports these moderate outcomes despite the broader 2026 summer running hotter than average under persistent high pressure. Model consensus shows limited warming potential, with any offshore shift needed for 74°F+ readings appearing unlikely in the near term. Traders are weighting the 68–69°F bin at 24% due to forecast uncertainty around exact cloud timing and wind strength, while probabilities above 75°F remain low given historical August maxima and current steering patterns. Updated model runs and NWS briefings tomorrow morning will refine these implied odds ahead of resolution.
