Official observations from Weather Underground at San Francisco International Airport (KSFO)—the market's resolution source—confirm the highest temperature on April 21, 2026, reached 62°F around midday under mostly cloudy skies with 0.65 inches of light rain and gusty winds up to 26 mph, aligning perfectly with trader consensus at 100% implied probability for 62-63°F. This outcome reflects persistent marine layer influence and cool Pacific air masses typical for mid-April in San Francisco, where historical daily highs average 63-65°F amid frequent fog and drizzle. National Weather Service data similarly reports a peak near 63°F with light rain, reinforcing the positioning. Realistic challenges would require a rare data revision from automated sensors or station metadata corrections, though such adjustments are infrequent post-preliminary reporting.
