Trader consensus on Polymarket has reached 100% implied probability for a 64-65°F high temperature at San Francisco International Airport (KSFO) on April 10, driven by official observational data from the National Weather Service and Weather Underground confirming the peak reached 64.4°F amid persistent marine stratus clouds and cool onshore southerly winds around 10-20 mph. This aligns with NWS forecast model consensus predicting mild conditions under overcast skies, consistent with mid-April climatological averages of 63°F and recent patterns of coastal fog limiting solar heating. Realistic challenges include rare post hoc data revisions from instrument calibration issues, though KSFO measurements carry high reliability with negligible revision history for such events.
