The temperatures in Provence are still very hot right now. Though beautiful as always, the region seems a little worn, a little tired, after a busy summer. Even my favorite Joucassienne dog is a little wiped out from the heat. Remember my picture of him from last year in June?
Thus, I think I would prefer to visit Provence in June as opposed to the end of August and early September. However, it is much easier to get a table in a restaurant without a reservation at this time of the year. Still beautiful, still intoxicating, the Luberon seems to be recovering from a busy summer and the scorching heat. But who can complain with a view like this from your gite rental.
