As a FL resident, I can say, it definitely is not always hot and rainy in Florida! Saying that, I generally avoid Disney from June-August, as that is the hot & rainy season of the year. I really love late April/Early May and November/December and late January. These are all slower seasons at the park, and the weather is more temperate than other times of the year. Winters can be chilly or beautiful an in the 70s, so every year is a bit different!
