Trader consensus on Polymarket has locked in at 100% implied probability for a 62-63°F high temperature in San Francisco on May 3, 2026, driven by Weather Underground's official KSFO station data confirming a maximum of 63°F at 1:56 PM and 2:56 PM amid mostly cloudy skies and southwest winds gusting to 18 mph. Persistent marine stratus from the cold California Current capped daytime heating, aligning with National Weather Service pre-event forecasts near 65°F but moderated by slow burn-off and light rain (0.03 inches), consistent with May climatology at KSFO where highs average 63°F. Rare challenges could arise from data revisions or station discrepancies, though ASOS observations provide robust verification; no further updates expected as the market nears resolution.
