You can go into the water without shoes.

Mid August to November, 20 knots 5 times a week. Rest of the year 20 knots 2 to 3 times a week. The wind is mainly geothermal, so with sun on the mountains and a good direction, there is a kind of centrifugal effect in the channel between Ilhabela and Sao Sebastiao from the afternoon until the end of the day. Forecasts don't predict the venturi effect. Only NE gives a straight wind through the channel. With all other directions you have to take into account variation in direction and wind strength. When you start make sure you pass and cross the mooring lines. There is good wind above the spot. If you come below it, the wind direction will be against you and you can do your best getting upwind to avoid a walk.
