Official National Weather Service observations at Miami International Airport placed the June 8 overnight low squarely in the 80–81°F range, driving near-certain market consensus. Early June subtropical conditions feature elevated dew points and persistent Atlantic moisture that limit radiative cooling, producing typical minima of 75–80°F with little day-to-day variability. Recent model guidance showed no intrusions of drier air or frontal passages that could have produced greater overnight drops. While measurement revisions or station-specific anomalies remain theoretically possible, the alignment of forecast data, climatological norms, and final recorded values leaves virtually no realistic pathway for a materially different outcome.
