Persistent high pressure and limited nocturnal radiative cooling under partly cloudy, humid conditions are positioning Miami's August 13 minimum near 78–81 °F, aligning with the market's leading 78–79 °F (35.5 %) and 80–81 °F (27.5 %) bins. Official guidance from the National Weather Service and ensemble models shows overnight lows historically averaging 78–80 °F in mid-August, with recent nights running 2–4 °F above normal at 81–84 °F. Weak easterly flow, minimal cloud cover reduction, and Gulf moisture are expected to moderate the daily temperature range, keeping the low above 76 °F while making sub-75 °F outcomes unlikely absent an atypical cold front. Updated model runs and evening observations will refine these probabilities ahead of resolution.
