Miami's subtropical climate and warm Atlantic/Gulf waters typically limit overnight radiational cooling in mid-August, anchoring daily minimum temperatures near 80–82°F according to National Weather Service climatology and recent observations. Current National Weather Service point forecasts and ensemble guidance show little deviation from this baseline for August 12, with high boundary-layer moisture and weak steering flow suppressing stronger cooling or heat advection. Recent minima near 82°F on August 9–10 have reinforced trader confidence in the 80–81°F bin as the mode, while the spread to 78–79°F and 82–83°F captures minor model variability in cloud cover and thunderstorm timing. No tropical systems or anomalous pressure patterns are expected to shift the outlook before resolution.
