The latest National Weather Service point forecast and ensemble models from GFS and ECMWF converge on a Miami high temperature of 80-81°F on March 22, fueling its leading 34.5% implied probability in a tightly contested market. Differentiating factors include remnants of a weak cold front moderating earlier 82-83°F potential, robust sea breeze penetration by midday for coastal cooling, and ample sunshine maximizing peak insolation around 2 PM local time. Historical averages for this date hover near 79°F, but persistent upper-ridge influence tilts toward mild warmth; persistent 2-3°F model spread underscores uncertainty in boundary-layer mixing and diel heating, keeping 78-79°F and 82-83°F viable at 27% and 24%. Traders eye afternoon forecast updates for shifts.
