Current forecast models from NOAA and the National Weather Service indicate typical mid-May subtropical conditions for Miami, with overnight lows most likely settling in the mid- to upper-70s due to persistent easterly flow from the Atlantic subtropical high and elevated dew points that limit nocturnal cooling. Recent model runs show only modest differences in cloud cover and wind speed that could shift the low by a degree or two, keeping the 74–79°F range tightly bunched in trader pricing. Historical climatology places average May lows near 76°F, with rare excursions below 73°F absent a strong frontal passage, which current guidance does not support. Updated GFS and ECMWF runs expected over the next 48 hours will refine the precise minimum before the May 18 observation window closes.
