Official National Weather Service observations from Miami International Airport recorded a maximum of 87°F on October 3, 2026, reached in the early afternoon under mostly cloudy skies with light easterly flow. This value aligned closely with seasonal normals near 88°F and fell well within the typical late-summer range for the region, where diurnal heating and Atlantic moisture moderate extremes. Multiple independent reports, including preliminary climatological summaries and real-time station data, converged on the same narrow band, producing the market's complete consensus on 86-87°F. Revisions to the final certified record or use of an alternate coastal station remain the only realistic paths that could alter resolution.
