We are here now and there seems to be much more rain then there has been in the past during the same time of year. I've always remembered it raining, but clearing up after an hour or so. The last few days have been scattered thunderstorms all afternoon into evening.
Weather wise as PP has said, its hot and humid, so stay hydrated. Remember you can get ice water from QS were they have soda dispensers. This has helped us a great deal because we don't have to use our quick service on bottled water.
If you are not used to humidity, remember it makes it feel hotter than it really is.
