The best place for kite surfing really depend from the condition and the direction of the wind: during the wet season as far as we know people fly mainly in Sanur and Jimbaran.
During the dry season still the most popular place is Sanur but kiter can travel to experience different conditions like Balian and Tulamben.
There is been reports of kite
surfer in Kuta but in the wet
season the west wind is to on shore and in the dry season is to off shore.
Nusa Dua have almost the same condition of Sanur in the dry season but is not very popular as to many motorized watersport and tourist are around.
