Official National Weather Service observations at San Francisco International Airport recorded a daily maximum of 73°F on August 24, 2026, aligning closely with the market's dominant 70-71°F outcome amid typical late-summer marine layer conditions that moderate coastal temperatures through onshore flow and haze. Historical climatology for the date shows average highs near 70°F with frequent suppression below inland values, reinforcing trader consensus around this narrow band based on verified station data. Resolution criteria tied to specific monitoring points further support the positioning. A shift in prevailing winds reducing the marine influence or an unusually strong offshore flow could elevate readings, though such patterns remain improbable given current synoptic conditions.
