Official National Weather Service observations from Miami International Airport (KMIA)—the market's authoritative resolution source—confirm the highest temperature on April 30 reached 87.1°F around 1 p.m. local time, with subsequent hourly readings peaking no higher at 87°F amid mostly sunny skies, light southeast winds, and high humidity. This aligns precisely with pre-event NOAA forecast model consensus projecting highs near 86°F under typical late-April conditions, slightly above the 85°F climatological normal but without anomalous heat drivers like upper-level ridges. Trader consensus at 100% implied probability reflects verified ASOS automated sensor data, with negligible risk of revision; only an unprecedented data correction in the final daily climatological report could challenge it, though historical precedents show such changes are exceedingly rare for settled observations.
