Official observations from the National Weather Service at San Francisco International Airport (KSFO) confirm the highest temperature on April 20 reached 64-65°F, driving Polymarket traders to a unanimous 100% implied probability on this outcome as the definitive recorded high per Weather Underground data used for resolution. Persistent marine layer and cool onshore flow under high pressure suppressed warming, aligning with pre-event National Weather Service forecasts projecting a high near 63°F amid typical mid-April climatology, where SF averages 62-65°F highs. With the observation period closed, only an exceedingly rare data revision by NOAA—such as sensor malfunction verification—could challenge this positioning, though historical precedents show such adjustments affect less than 1% of daily records. Traders await final daily climate summary for closure.
