I found this article in Italy Magazine.  It is a free magazine you can subscribe to which I find very helpful. With the high heat in Europe this summer this article may be of interest to you. Some great ideas of how to beat the heat, and where to visit.

Last summer we arrived in Sicily in mid August. It was hot but the beaches were cooling. So were some of the high altitude areas as well as Lake Garda.
