August was our "month of choice" once the kids became too old to take out of school for a trip. The rates at the resorts would go down around mid-August and Disney even offered *free* dining during that period when they first introduced it.
It's very hot but even worse, it is extremely humid. We rarely stayed in the parks during the afternoon, usually choosing to return to our resort for a swim or to rest in the air-conditioned room.
It also rains pretty much every day. Sometimes it's just a brief shower. But other times, it's a heavy downpour!
Finally, the park hours get cut back after the regular summer season ends. That means that there are fewer Fantasmics!, less opportunities to see MSEP, and you will have less time to tour the attractions.
My advice, if you choose to go in August, is:
- stay hydrated
- start early when the heat is at its lowest
- take mid-afternoon breaks to avoid the storms and worst of the heat
- return to the parks in the early evening when the sun begins to set
- pay attention to when the evening shows will be if seeing them is important to you
- take extra shoes so that when one pair gets soaked, you will have something to wear in your feet
- have alternate plans in case of an all-day rain
