Official National Weather Service observations confirm Miami reached a maximum of 90°F on October 11, 2026, three degrees above the 1991–2020 normal of 87°F and well below the date record of 92°F set in 2009. This outcome aligns with a multi-day stretch of above-average warmth across South Florida, where afternoon temperatures consistently hit 90°F amid light winds and only modest afternoon convection that failed to suppress the peak. Market-implied odds at 100% for the 90–91°F bin reflect the finality of verified station data from Miami International Airport, leaving negligible room for revision once the climatological report is issued. Rare measurement discrepancies or station-specific microclimate variations could theoretically alter resolution, though such shifts remain highly improbable given standardized NWS protocols.
