Florida Weather in September

What's the weather like in Florida in September?

The location of Florida in the southeast of the United States close to the Tropic of Cancer means the state has a stunning climate that gives it the nickname of the ‘Sunshine State’. September’s perhaps the last of the true summer months, when you'll get temperatures still pushing the mercury over 30º. Things don't really cool down too much over ‘winter’ though.

Climate

The peninsula Florida sits on splits the North Atlantic Ocean in the east from the Gulf of Mexico to the west, and the state’s climate is subtropical in the north and tropical to the south. This means temperatures are high all year round, while the weather’s generally kept quite stable because there’s so much surrounding water. Rainfall’s most common over summer, although this will often fall in brief, heavy downpours or thunderstorms that quickly clear.

Averages

In iconic Miami the average high’s 31ºC in September, which only drops to a balmy 25ºC at night so you'll still be nice and warm. The sea temperature’s also warm at 29ºC, which is great for swimming, while humidity’s very high. Average rainfall’s 178mm over 17 rainy days, although you can still expect nine long hours of sunshine at a high UV level from the 12 hours of daylight each day so don't forget the sun cream. Sunset’s at 7.40pm at the start of the month, and gradually gets earlier.
