Official observations from the Miami International Airport station (KMIA), as reported by Weather Underground, confirm the highest temperature on March 27, 2026, reached 82°F around midday and early afternoon, locking in trader consensus at 100% implied probability for the 82-83°F outcome. This aligns precisely with the late-March climatological normal of 82°F, amid partly cloudy skies, no precipitation, and breezy east-southeast winds up to 21 mph gusts that capped daytime heating by enhancing mixing and evaporative cooling. Strong scientific evidence from automated surface observing system data supports this positioning, with minimal uncertainty barring rare post hoc data revisions from quality control processes—such as sensor recalibrations—that could nudge it into adjacent bins if anomalies are detected upon final National Weather Service review.
