Trader consensus on Polymarket heavily favors 82-83°F (33.5%) as Miami's highest temperature on March 28, driven by the latest NOAA Weather Prediction Center ensembles averaging 83°F amid a strengthening subtropical ridge promoting subsidence and warm advection from the Gulf. Supporting this, GFS and ECMWF models show peak heating under light southerly winds, with sea surface temperatures near 78°F fueling humidity-driven warmth. Lower odds for 80-81°F (22.5%) or below reflect minimal cold front threats, though sea breeze penetration could cap peaks; extremes like 90°F+ (under 4%) hinge on unforecast heat bursts. Uncertainty stems from model spread on upper-level trough timing, with NWS updates expected by March 27. Historical March 28 highs average 81°F, contextualizing the mild bias.
