The dominant market consensus on a 72-73°F low for Miami on June 4 stems from the official National Weather Service observation at Miami International Airport, which recorded a minimum of 73°F shortly after midnight under typical early-summer conditions. This aligns closely with climatological normals of 74-76°F for the date and recent model guidance showing minimal overnight cooling amid high humidity and light winds. Traders priced the outcome near certainty once preliminary station data confirmed the reading, with negligible probability assigned to outliers given the absence of atypical frontal passages or enhanced radiational cooling. Minor revisions to the final certified value remain possible but unlikely to shift the result outside the leading band.
