September starts the very slow transition toward winter and the dry season for central Florida. Even so, measurable rain occurs on nearly half of days, primarily as afternoon or evening thunderstorms. Lightning is a deadly threat, so always move indoors when you hear thunder. Heat and humidity remain a significant issue that should be planned for. Having said that, days above 90 degrees become less frequent in September, and occasional surges of drier and somewhat cooler air can occasionally make it into central Florida.

September is the peak month of the Atlantic hurricane season. Tropical systems can approach Florida from the east and southeast, and potentially from the Caribbean or Gulf. If you are planning a vacation at this time of year, you should keep up to date with tropical activity.
