Miami’s subtropical climate features persistently high humidity and frequent cloud cover or scattered thunderstorms that suppress nocturnal radiational cooling, anchoring overnight lows near the 78°F August climatological average. Model consensus and recent observations point to light southeast winds and partly cloudy skies overnight into August 6, favoring minimum temperatures in the 78–81°F range, while any increase in convective activity or thicker marine-layer moisture could allow readings to dip into the mid- to upper 70s. Traders assign comparable weight to the 78–79°F and 80–81°F bins because small variations in timing of sea-breeze convergence or evening convection remain the dominant sources of forecast uncertainty at this lead time.
