Many people windsurf at theBerkeley Marina, port to many watercrafts, which is located at the western end of University Avenue. The wind season runs here from April to October.

One of the best places to start windsurfing! The little bay protects from strong wings and the predominant wind blows towards land. When you are more adventurous you can windsurf to Emeryville Marina and back. Just don't end upon the toilet bowl. The motor boats will have to come and tow you back towards port. 

Organizations offering windsurfing at the marina include Cal Sailing Club and Cal Adventures. They provide equipment and classes to beginners and experienced windsurfers alike.

The eastern most port is the launching pad for more experienced windsurfers. They usually have their own equipment. Sometimes they host actual races and events from here as well.
