Miami Weather In September

Miami Weather In September is no better than August, and although cooler temperatures are coming you won't be able to tell it even by the end of the month. Rainstorms, often in the form of violent thunderstorms, occur just about daily. You will rather be in the water than sitting next to it with a drink.
