Forecast models from the National Weather Service and private sources indicate overnight lows in Miami on August 28 will likely range from the upper 70s to low 80s°F under mostly clear to partly cloudy skies with light easterly flow and dew points near 76–78°F. These conditions limit radiative cooling while subtropical humidity sustains warmth, aligning with the market's tight clustering around 78–83°F outcomes. Afternoon sea-breeze convergence and isolated thunderstorms may briefly disrupt diurnal heating but have minimal overnight impact. Historical August climatology shows average lows near 77.5°F, with recent years often recording 79–81°F minima absent frontal passages. Updated model runs and evening observations will refine the final minimum before resolution.
