Miami's subtropical climate typically produces overnight lows near 78–80°F in early August due to high humidity, minimal radiational cooling, and Atlantic moisture. Trader consensus centers on 78–83°F ranges because short-term forecast models show minor variations in cloud cover, thunderstorm timing, and wind patterns that can shift the daily minimum by a degree or two. Recent stable high-pressure dominance has kept conditions consistent with climatological averages, though any increase in convective activity overnight could suppress the low toward the 78–79°F bin while clearer skies would favor 82–83°F. Updated National Weather Service model runs and local observations will refine these probabilities ahead of resolution.
