August is hot....

No matter what time in August you might be visiting, just know that the temperature will be in the mid eighties to nineties and that it will be extremely humid.
Crowds are generally lighter in August as opposed to June or July, but don't expect the parks to be empty. There's also the frequent Thunderstorms which tend to disperse the crowds. (Plus!!)
Overall, August is a busy month, it's extremely hot and humid, and it frequently rains (pours). Your trip can be amazing if you time and plan accordingly.
If you're definitely going in August, you might need to start getting your ADRs ready. Start making reservations now. August is moderately to extremely busy, so your dining options may be limited.
Another tip: respect the sun! Wear sunscreen, and stay hydrated. Escape the crowds and the sun by doing minor attractions in the afternoon (eg. Country Bears, POTC, Tiki Room, Monster's Inc, Stitch).
Finally, I strongly recommend that you arrive at the parks at rope drop (opening time) to take full advantage of the major attractions and headliners.
Good luck, and have a magical trip!
