In winter you must use wetsuits (5-6 mm or more), in summer you can use 2-3 mm or short wetsuit, or if you prefer you can avoid to use it at all. You can really kite all over the year, but the best months are from April to October. During the winter you must only be careful about the very cold water.
In the morning Pelér starts at about 6-7am and blows from the North of the Lake until 10-11am, it's a great wind (15-30 knots) for good and advanced kiters, it depends in which area you want to go out for kiting and you can find good waves, it's a little bit gusty. In the afternoon Ora starts at about noon to 1pm and blows from the South of the lake until 5-6pm, it's the best wind (15-20 knots): very steady.
