Trader consensus has locked in 80-81°F as Miami's highest temperature on March 23, driven by NOAA's National Weather Service forecast models showing peak highs in that narrow band under partly cloudy skies with light winds. Ensemble predictions from GFS and ECMWF align closely, reflecting mild late-winter conditions with sea surface temperatures around 78°F capping extremes, consistent with Miami's March climatology averaging 79-82°F. Historical data shows rare deviations above 85°F this late in the season absent a strong high-pressure ridge. Realistic challenges include an unforeseen amplification of the subtropical ridge or downslope winds, potentially nudging temps toward 82-83°F, though current upper-air analyses indicate low likelihood.
