Recent NOAA and NWS model consensus supports overnight lows near 80–82°F in Miami on August 23, driven by persistent subtropical humidity with dew points in the mid-70s that sharply limits nocturnal radiative cooling. Partly cloudy skies from scattered afternoon convection further moderate temperature drops, while light southerly winds prevent stronger inversions. These factors explain why the 80–81°F and 82–83°F bins dominate trader positioning at 42.5% and 33.5% implied probability, respectively, with narrower spreads reflecting forecast uncertainty in exact minimum timing and localized cloud effects. Historical August averages near 80°F provide additional context for the tight clustering around these outcomes.
