**Forecast consensus from the National Weather Service and other models points to an overnight minimum in the low 80s°F for Miami on August 30, 2026, aligning with the market's leading outcomes clustered around 78–83°F.** Persistent easterly flow off the Atlantic, combined with high dew points near 78–80°F and widespread cloud cover from afternoon thunderstorms, limits nocturnal radiative cooling and keeps temperatures elevated. This pattern is typical for late-August Miami under a moist tropical airmass, where overnight lows rarely drop below the upper 70s without a drier, clearer intrusion. The tight spread in implied probabilities (80–81°F at 32.5%, 78–79°F at 25%, 82–83°F at 22%) reflects modest model and timing uncertainty in exact minimums, particularly around the influence of lingering showers or variable cloud breaks between roughly 2–8 a.m. EDT. Stronger or more persistent convection could suppress the low slightly toward 78–79°F, while clearer intervals or slightly stronger winds might hold it near 82–83°F. Historical August minima average near 78°F, but current conditions favor the warmer side of that range. Updated NWS guidance and model runs through the weekend remain the key near-term catalysts.
