Miami Weather in September

Miami's subtropical climate means hot, humid summers with daily afternoon thunderstorms driven by Atlantic sea breezes colliding with Gulf air, and warm, dry winters that attract millions of visitors. The city sits at sea level on a limestone peninsula between Biscayne Bay and the Atlantic Ocean, giving coastal neighborhoods constant ocean breezes while inland areas bake in intense urban heat. Hurricane season runs June through November, with the entire metro exposed to major storm risk.

Excellent shoulder season — warm with fewer tourists in many destinations.

Miami's climate is tropical — warm year-round with a distinct dry season (November–April) and wet season (May–October) that brings daily afternoon thunderstorms and hurricane risk. The winter from December–March is essentially perfect outdoor weather.
