Current forecast guidance from NOAA and private models shows Miami overnight lows for July 6 centered on 79–81°F, consistent with July climatology where the average minimum sits near 78–80°F under the persistent subtropical ridge. Light southeast flow, sea-surface temperatures near 85°F, and high boundary-layer moisture limit nocturnal cooling, while scattered afternoon thunderstorms offer only modest relief before clearing. Trader positioning clusters tightly around the 78–81°F buckets because ensemble spreads remain narrow this close to the event, with resolution hinging on the official Miami International Airport minimum reported by the National Weather Service. No significant model shifts or atypical steering patterns have emerged in the past 48 hours to alter the baseline outlook.
