Current National Weather Service and ensemble model guidance points to a highest temperature in Miami on August 3 near the seasonal normal of 91°F, with afternoon sea-breeze convergence and scattered thunderstorms likely capping peaks in the low 90s. Persistent warm, humid air under weak steering flow supports readings of 90–93°F, while variability in convective timing creates the tight spread between the two leading bins at 42.5% and 35.5%. Typical August climatology shows highs rarely exceed 93°F without a stronger ridge, and recent heat-advisory conditions reflect the same moist boundary layer expected tomorrow. Updated model runs and NWS briefings through the morning will refine the exact maximum before market resolution.
