Official National Weather Service observations recorded a minimum temperature of 78°F at Miami International Airport on October 13, 2026, aligning precisely with the market's dominant 78-79°F outcome. This reading followed forecasts projecting overnight lows in the upper 70s amid mostly clear skies, light northeast winds, and typical early-October humidity levels that limited radiational cooling. The value sits above the 1991-2020 climatological average low near 75°F yet well within the 95% historical range of 67-80°F for the date. Market-implied odds reflect trader consensus on these verified station data, with resolution hinging on the final NWS climate summary. Unlikely revisions to the preliminary report represent the primary scenario that could shift positioning before formal settlement.
