National Weather Service observations at Miami International Airport (KMIA) confirm the lowest temperature on April 25, 2026, reached 72°F around 6 a.m. EDT, as recorded by the automated surface observing system (ASOS) in hourly METAR reports, driving trader consensus to a 100% implied probability for the 72-73°F outcome. Light southerly winds under 5 mph, dew points near 66°F, and partly cloudy skies limited radiational cooling despite pre-dawn high pressure aloft, exceeding earlier NOAA forecasts of 70-71°F lows amid urban heat island effects typical for late April—when climatological minima average 71°F. With data now finalized per Wunderground-archived NWS measurements for market resolution, only an improbable quality control revision, such as sensor recalibration, could alter positioning; no further updates are anticipated.
