Persistent high humidity and easterly flow across South Florida are keeping overnight lows elevated for Miami on August 29, with official National Weather Service guidance pointing to minimums near 81–84°F amid scattered thunderstorms and limited radiational cooling under partly cloudy skies. Dew points remaining in the mid-70s suppress temperature drops typical for late August, when climatological averages hover around 77–78°F, while light winds limit mixing that could otherwise allow brief dips. Model consensus favors minimal overnight clearing, reducing odds of the 78–79°F outcome favored by traders and tilting sentiment toward the tightly clustered 80–83°F bins. Thunderstorm timing and any unexpected boundary-layer moisture shifts represent the key variables that could still nudge the recorded low.
