Official temperature records from Miami International Airport and surrounding NOAA stations confirm that the daily high on May 16 reached the 88–89 °F range, aligning with the market’s near-certain outcome. Mid-May climatology for southeast Florida typically features highs of 85–88 °F under prevailing easterly flow and moderate humidity, with only modest day-to-day variability driven by sea-breeze convection rather than large-scale synoptic changes. Recent model runs from the National Weather Service showed minimal deviation from these seasonal baselines, leaving little room for an outlier spike above 90 °F. A sudden shift in steering winds or an unforecasted mesoscale feature could have altered the reading, yet no such development materialized in the final 24-hour verification window.
