Latest National Weather Service forecasts and GFS/ECMWF model ensembles project Miami's highest temperature on April 13 around 79-81°F under mostly sunny skies with persistent east-northeast winds of 10-15 knots, driving 43% implied probability for the 80-81°F bin as traders weigh suppressed sea breeze development against climatological April normals near 83°F. Over the past 48 hours, observed highs of 77-80°F amid light showers and onshore flow have cooled sentiment away from 82°F-plus outcomes, with 25.5% on 82-83°F reflecting potential for better mixing. Inherent forecast uncertainty persists from cloud cover variations and upper-level ridge positioning; watch Saturday's 12Z model runs for refinements ahead of Sunday resolution at Miami International Airport.
