Hi, i have heard the weather in september is still very warm, but without the humidity you would get in July/Aug.

The club Julian is very good for kids, but it is about a 15mins walk to the beach. You could get the dolmus though, this is very quick.

We went end of August/beginning of September - it was v. humid, but even some of locals said it was unusually so. It was lovely and warm though, and the humidity did lift after it raining slightly (on the evening of the hotel garden party!).

The Arum in Side has a good kids club, great pools, and a decent beach. However, it is lacking in good evening entertainment (but lots of better stuff just a short walk up the road).
