Persistent heat and elevated dew points across South Florida are the main drivers behind current Polymarket positioning for Miami’s August 1 minimum temperature. Official forecasts from the National Weather Service and AccuWeather project overnight lows of 77–83 °F amid ongoing heat advisories, with limited nocturnal cooling expected under partly cloudy skies and high humidity typical of early August. Historical climatology shows an average August minimum near 78 °F at Miami International Airport, so the market’s heavy weighting toward 86 °F or higher (47.5 %) alongside the 78–79 °F bin (37.5 %) reflects trader assessment of whether urban heat-island effects and model consensus will push the reading above or near the upper end of the normal range. Updated National Weather Service guidance and any late-day convective activity remain the key variables that could shift implied probabilities before resolution.
