Trader consensus on Polymarket tilts toward a Miami high of 82-83°F (28.5% implied probability), driven by the National Weather Service's latest forecast pinning the peak at 82°F amid a warming southerly flow from the Gulf. Close behind at 25.5% odds for 80-81°F reflects model ensemble spread, with ECMWF leaning slightly cooler due to enhanced sea-breeze circulation off warmer Atlantic waters (around 76°F SSTs). Differentiating factors include afternoon cloud development from diurnal heating—potentially capping peaks below 82°F—and urban heat island effects boosting readings at official stations like MIA. Historical late-March averages hover at 79°F, but persistent ridging aloft favors the upper cluster, though convective showers introduce 10-15% downside risk for sub-80°F outcomes. Key watch: 48-hour forecast updates for refined sea-breeze timing.
