Forecast consensus from the National Weather Service and major models positions a daily high near 89–90°F for Miami on August 27 as the most likely outcome, aligning with the market's leading 90–91°F bin. Persistent southeast flow, high humidity, and heat indices exceeding 100°F support temperatures in the upper 80s to low 90s under partly to mostly sunny skies, while scattered afternoon thunderstorms—carrying roughly 50% probability—introduce limited cooling potential through cloud cover without widespread suppression. This aligns with typical late-August climatology for the region, where peaks rarely deviate sharply absent stronger frontal or tropical influences. Updated model runs and any morning observations will provide the final data points before resolution.
