NWS Miami forecasts and supporting model guidance position a daily high in the lower 90s as the most probable outcome for August 23, driven by mostly sunny morning conditions with patchy smoke, light southerly winds, and afternoon convection that typically develops by mid-afternoon in South Florida’s humid summer regime. This aligns with the long-term August average high near 91°F and recent days featuring similar 90–94°F readings without anomalous ridging. High humidity keeps heat indices above 105°F, but scattered thunderstorms—expected to initiate after peak heating—often cap maximum temperatures by enhancing cloud cover and evaporative cooling. Updated radar trends and hourly observations through the afternoon will provide the clearest signals for whether the peak settles at 92–93°F or edges slightly higher.
