Seattle's August 4 high-temperature market reflects a warm, stable pattern under high pressure, with NWS forecasting sunny conditions and a peak near 82°F amid light northerly winds. Traders assign nearly equal weight to the 82-83°F and 84-85°F bins because official guidance can vary slightly from urban measurements, and subtle differences in afternoon mixing or marine-layer timing introduce uncertainty around the exact maximum. The broader summer context of above-normal temperatures—the 14th consecutive hotter-than-average season—supports elevated readings, while climatological August averages near 76°F highlight the current anomaly. Key near-term factors include continued clear skies and minimal cloud cover, with any model consensus shifts or updated NWS briefings likely to refine the tight market spread before resolution.
