Official National Weather Service forecasts for Miami International Airport point to an overnight low near 81°F on August 9, with temperatures settling into the upper 70s to low 80s under mostly clear to partly cloudy skies and light easterly winds. A recent shift to drier conditions across South Florida has reduced thunderstorm activity and associated evaporative cooling that typically moderates summer lows, supporting the market's heavy weighting toward the 82-83°F bracket. Subtropical humidity and urban heat retention further limit radiative cooling, keeping minimums above climatological norms for early August. Updated model runs and any late-day convection before sunrise remain the key variables that could nudge the final observed low.
