THe past few years we always head down for a week on Aug. 8 (totally by coincidence, but it must be a lucky number for us because we always have a blast!) Its hot, obviously, and afternoons are often less than pleasant. but we never really are bothered. get nice loose clothing, a good hat and sunblock, and drink lots of water (even if you arent thirsty like a PP said). Rope drops and EMH may be your new friend. we find it best to go first thing, have an earlier lunch around 1130 or 12, and then go to the hotel for naps, showers, swim, etc. We also like not having a hot car ride, those disney buses have AMAZING a/c lol. also, check your local walmart-type store for small pocket misters. those disney fans are big and expensive, but i found a 3 pack of pump misters that we take, fill up and put in the fridge the night before, and we can easily refill them at a water fountain. and they fit in a little backpack. have a fun trip!!
