Recent National Weather Service and model guidance indicate overnight lows in Miami of 80–82°F for August 9, aligning with the market’s tight leading bins at 82–83°F (38.5%) and 80–81°F (33.5%). High humidity, dew points near 75°F, and light east-southeasterly flow are limiting radiational cooling, while scattered clouds and residual tropical moisture from recent showers further suppress overnight temperature drops. These conditions sit above the long-term August average low of ~78°F, reflecting persistent warm advection rather than typical clear-sky cooling. Updated model runs and evening observations over the next 12–18 hours will refine whether the minimum settles near 80°F or edges into the low 80s.
