Official National Weather Service observations at Miami International Airport (KMIA) recorded a peak temperature of 91°F on May 9, 2026, at 2 PM and 4 PM EDT, solidifying trader consensus at 100% implied probability for the 90-91°F outcome as the market nears resolution. Hourly data from the automated surface observing system showed temperatures rising from morning lows near 76°F under partly cloudy skies and south-southeast winds of 5-10 mph, surpassing the climatological normal maximum of 86°F for early May but well below the record 95°F set in 2010. This warmer-than-average reading aligns with recent high-pressure ridging over Florida, boosting surface heating. With data now finalized in daily climate summaries, realistic challenges are minimal—only an official revision from NOAA or discrepancies in final quality-controlled records could shift positioning, though none are indicated.
