Official observations from the San Francisco International Airport (KSFO) station, as reported by Weather Underground, confirm the highest temperature on May 5, 2026, reached 64-65°F, driving trader consensus to a near-certain 100% implied probability for this outcome on Polymarket. Persistent marine layer stratus clouds and gusty westerly winds up to 24 mph suppressed daytime heating, aligning with typical May climatology where average highs hover around 66°F but fog frequently limits peaks. Hourly data peaked midday under partly cloudy skies with trace precipitation, solidifying the measurement. Realistic challenges include rare post-finalization revisions from sensor recalibrations or overlooked late-day readings, though NWS data quality checks make this unlikely; resolution awaits data lock.
