National Weather Service observations at Miami International Airport (KMIA) confirm the highest temperature reached 84°F on April 29, 2026, around 2 p.m. local time, with hourly Automated Surface Observing System (ASOS) readings peaking there before dropping to 83°F amid sea breeze influences and scattered clouds moderating daytime heating. This aligns precisely with pre-event forecast consensus from GFS and ECMWF models, which implied highs in the 84-85°F range under light southeasterly winds and typical late-April climatology (normals around 85°F maximum). Trader consensus at 100% on 84-85°F reflects this verified data, backed by real-money positions; realistic challenges would require rare post hoc data revisions from instrument anomalies, though NWS daily climatological summaries rarely alter established highs.
