Ensemble forecasts from NOAA's GFS and ECMWF models, alongside National Weather Service guidance, drive trader consensus toward highs of 80-83°F in Miami on March 27, with 82-83°F leading at 29.5% implied probability due to persistent ridging aloft and warm Atlantic sea surface temperatures around 78°F boosting daytime heating. Differentiating factors include diurnal sea breeze onset timing—earlier onshore flow favors 78-79°F (21.5%) by enhancing coastal cooling, while delayed breezes or light southerlies allow 82-83°F peaks. Urban heat island effects and minimal shower risk add ~1-2°F variability, tightening odds amid neutral ENSO conditions and historical March averages near 80°F; watch afternoon updates for shifts.
