Just wanted to add to this topic, we went to Calis at the beginning of last October and the weather was lovely apart from a couple of storms, but I am glad we didn't go any later for several reasons, it gets dark very early in the evenings, not a lot of spectacular sunsets!! and the water taxi into Fethiye stops running in October, and we love this trip across the water. Also there were a limited amount of boat trips available, and if you are looking for night life then you are in the wrong place at the wrong time.
