and it can be extremely hot and humid especially during the peak of midday at times from past experience. If you haven't been in a climate where you are really used to 90 degree plus temperatures on a consecutive day-to-day basis, your system may be in for quite some shock at first depending on your individual level of tolerance. It can also be taxing on small children who aren't used to lots of sun exposure. I would suggest loads of light-colored clothing, sunscreen, hats, juice, water bottles, shades, keeping an eye on the weather report, and anything else you feel may be comfortable so as shield from the heat. August is bearable in WDW if you're very familiar with the conditions and know what to possibly expect in order to make preparations. Hope this helps some.
