Trader consensus on Polymarket favors a Miami high of 82-83°F at 30.5% implied probability, driven by the latest National Weather Service forecast models projecting mid-80s peaks amid a building subtropical ridge suppressing cold fronts. Ensemble guidance from GFS and ECMWF shows a clustered 82-85°F range (51% combined odds), exceeding the March 23 historical average of 79°F due to persistent clear skies and light winds limiting sea breeze moderation. Lower outcomes like 78-79°F (18%) hinge on unexpected convective showers or stronger onshore flow, while extremes below 71°F or above 90°F (<2% each) reflect rare deviations seen in only 5% of historical records. High uncertainty stems from model spread in diurnal heating and evening cloudiness, with 12Z updates pivotal for refining odds.
