Hi Sandra,
Welcome back to the Disney Parks Moms Panel and thank you for asking us another question!
I’ve visited Walt Disney World Resort several times in August, so I have some good news and some bad news for you. The bad news is that, during the summer months, it’s pretty rare to have a perfectly sunny day in Central Florida, without any rain whatsoever. The good news, however, is that these rain showers are usually limited to a downpour in the middle of the afternoon. Don't be afraid of the rain! Just throw on a poncho and go splash in the puddles while everyone else runs away!
What I would recommend for your upcoming visit is to plan your days so that you spend as many of the (somewhat) cooler morning hours as possible in the parks, followed by a return to your hotel for a rest/swim in the afternoon (when the rain is likely to take place), and then end your Disney day with a return to one of the Theme Parks or
Disney Springs for a little bit of nighttime fun. I’ve found that kind of a “touring plan” is the best way to beat the August heat.
Have a Magical Day and a wonderful trip next week!
Lynne
