Oven like!!! We too, have gone in August, the last week to be exact. It gets around 95 degrees with an afternoon shower or thunder storm around 2 to 3 pm. almost every day. We tried to do the parks during the day, but found it almost impossible. Animal Kingdom on very hot days is the worst, no shade and alot of outdoor attractions. We ended up doing this... had a nice breakfast in the morning, sat out by the pool (actually in the water the whole time) had lunch, then showered and changed just as the rain would roll in. The rain lasts about an hour. So by 4:00pm it had kinda cooled down a bit, and we headed to the parks then. They are opened late, so going in the afternoon and enjoying it, was better than sweltering during the day. AND I like the hot weather! Don't let August heat throw you. The parks are less crowded and you'll do much more in less time. You just cannot be at the parks comfortably in 95 degrees! It was MORE relaxing getting a slow start to the day, rather then racing out to get to the parks early! Have fun!
