Official National Weather Service observations at Miami International Airport (KMIA), the authoritative station for resolution, recorded a peak temperature of 91°F at 1 p.m. EDT on May 10, 2026, with adjacent hourly readings of 90°F at 2 p.m. and 3 p.m., solidifying trader consensus at 100% implied probability for the 90-91°F outcome. This aligns with early morning forecast models anticipating highs near 90°F under partly cloudy skies, sea breeze influences, and above-normal warmth for May's 86°F climatological average, though below the 96°F record. Scenarios challenging this would require rare post-verification data revisions by NWS, as observations are now finalized with no significant discrepancies.
