National Weather Service observations from Central Park, New York City's official climatological station, recorded a maximum temperature of 52°F on March 29, 2026, driving Polymarket traders to price the 52-53°F outcome at a 100% implied probability with overwhelming consensus. This aligns with late-March climatological norms around 55°F highs, following a cooldown from record warmth earlier in the month—such as 80°F on March 10—amid shifting upper-level patterns and cooler air masses. Forecast models from NOAA had converged on mid-50s peaks before the event, with minimal uncertainty in post-event verification. Realistic challenges would require a rare data revision from the NWS, as preliminary airport readings corroborated the Central Park measurement, solidifying resolution.
