Trader consensus on Polymarket favors a Miami high temperature of 82-83°F at 37.5% implied probability, closely trailed by 80-81°F at 27.5%, reflecting uncertainty in National Weather Service forecasts amid model ensemble spread. Latest NOAA guidance points to a high near 83°F driven by a building subtropical ridge promoting southerly winds and ample sunshine, with sea surface temperatures around 78°F supporting above-normal warmth for late March, when historical averages hover near 79°F. Disagreements among GFS (82°F), ECMWF (84°F), and Canadian models (81°F) underscore sensitivity to cloud cover and timing of any sea breeze, contributing to tight odds. New 12z model runs expected today could refine the outlook before the event resolves.
