Trader consensus on Polymarket assigns 100% implied probability to a highest temperature of 68-69°F in San Francisco on April 17, 2026, based on verified observational data from the Automated Surface Observing System (ASOS) at San Francisco International Airport (KSFO), as reported by Weather Underground—the market's resolution source. This positioning stems from official hourly records peaking at 68 or 69°F around midday amid mostly sunny conditions, light onshore winds, and typical spring marine layer dissipation, consistent with NOAA forecast model consensus predicting highs in the upper 60s after recent rainy weather cleared. Historical April averages hover around 64°F, making this mildly above-normal but unremarkable; only a rare post hoc data correction from NWS auditors could challenge resolution, though such revisions are infrequent for established readings.
