**Forecast models from the National Weather Service and other sources indicate an overnight low in Miami on August 25, 2026, most likely in the upper 70s to low 80s°F, with 80–81°F currently the modal range.** This reflects typical late-August conditions featuring high atmospheric moisture, easterly flow off the warm Atlantic, and limited nocturnal cooling under partly cloudy skies with scattered showers or thunderstorms possible. Dew points remaining near 75°F suppress temperature drops, keeping readings several degrees above the long-term average low of ~77.6°F. Recent model runs show consistency in this pattern, with no incoming cold fronts or drier air masses to enhance radiational cooling. Traders have weighted the 80–81°F and 78–79°F bins most heavily because ensemble guidance clusters there, while lower outcomes would require uncommon clear, calm conditions or an atypical dry slot. Upper bins above 82°F remain less favored absent stronger mixing or delayed cooling. Updated National Hurricane Center and local NWS briefings through August 24 continue to support this consensus ahead of the overnight period.
