**Official observations from the Miami International Airport ASOS station recorded a minimum temperature of 74°F on September 7, 2026, aligning precisely with the market's dominant 74-75°F outcome at near-100% implied probability.** This value, reported in real-time climate summaries and daily data feeds, reflects the overnight low reached around dawn under typical late-summer conditions of high humidity, light winds, and scattered showers that limited radiative cooling. Historical September normals place Miami's average daily minimum near 77°F, so the observed reading sits slightly below that baseline yet well above record lows. Because the date has passed and verified station data are now public, trader consensus rests on this authoritative measurement rather than forecasts. The only realistic challenges would involve an official data revision by the National Weather Service or a market rule interpreting "Miami" via a different station or threshold, both of which remain highly improbable given the consistency across sources.
