Official National Weather Service observations at Miami International Airport (KMIA) recorded the highest temperature of 87°F at 2:53 p.m. local time on April 26, 2026, anchoring trader consensus at 100% implied probability for the 86-87°F outcome as markets approach resolution. This peak, captured via automated surface observing system (ASOS) 1-minute measurements, aligns with pre-event forecast model consensus from NOAA ensembles predicting mid-80s highs amid partly cloudy skies, sea breeze moderation, and scattered thunderstorms that capped further warming—conditions evident in real-time METAR reports showing temperatures dropping to the upper 70s by late afternoon. Slightly above the 85°F climatological normal for late April, the reading reflects typical subtropical patterns with low departure risk. Scenarios challenging this include rare post hoc data audits or quality control revisions by NOAA, though historical precedent shows such adjustments affect less than 1% of daily records.
