Talked to a friend in Windermere, FL recently and she told me it's been unseasonably hot this May and that she can't imagine how much worse it will be in June. Last June, we visited just about the same days you will be there this year. It was hot, hot, hot. And when it wasn't hot, it was raining. We had rain ponchos and had to buy new ones because the oriiginals had been taken on and off so much they ripped. The important thing is to keep yourself hydrated. Besides, you're on vacation in Florida in the summer, it's supposed to be hot.
