Official National Weather Service observations at Miami International Airport (KMIA)—the market's resolution source—recorded a peak temperature of 87.1°F at 1 p.m. EDT on April 30, 2026, confirming the 86-87°F outcome with 100% trader consensus backed by real-money positions. This aligned precisely with NOAA forecast models projecting highs near 86°F amid a persistent high-pressure ridge fostering clear skies, light winds, and low humidity that capped daytime heating below climatological extremes. April normals hover around 85°F, and recent hourly METAR data showed steady warming from 78°F morning lows without convective interference. With data now finalized via automated surface observing systems, realistic challenges are negligible barring an unprecedented measurement revision from quality-controlled summaries.
