Official National Weather Service observations from the Miami International Airport (KMIA) automated surface observing system confirm the lowest temperature on May 9, 2026, fell within 74-75°F, driving trader consensus to a near-certain 100% implied probability for this outcome. This aligns precisely with pre-event NOAA forecast models projecting overnight minima near 73°F amid southerly winds, dewpoints in the mid-70s°F, and partial cloud cover that curtailed radiative cooling overnight. Early May climatology at KMIA supports such readings, with average lows around 73°F and historical May 9 minima rarely dipping below 71°F due to South Florida's maritime influence and urban heat island effects. Realistic challenges would require rare data revisions from verified ASOS records, with final quality-controlled reports expected soon from the Local Climatological Data program.
