Trader consensus on Polymarket closely splits between 78-79°F (36.5%) and 76-77°F (33.0%) for Miami International Airport's highest temperature on March 29, driven by National Weather Service guidance projecting upper 70s peaks amid a subtropical high pressure ridge fostering light east-southeasterly winds and partly cloudy skies. Differentiating factors include sea breeze timing—earlier onshore flow from Biscayne Bay could cap heating at 76-77°F through enhanced mixing and coastal cooling, while delayed onset permits greater solar insolation for 78-79°F. Ensemble forecasts from GFS and ECMWF models show tight clustering around 77-78°F, consistent with late March climatology averaging 79°F highs. Minimal precipitation risk persists, but afternoon cloud development remains a key variable; watch for NOAA updates this evening ahead of tomorrow's observations.
