In attachment, you can find a really useful and detailed kitesurfing and windsurfing spots guide for San Francisco Bay Area, that friends from USA have highlighted to me.
Spots are described, both from the point of view of conditions that you can find in the water, and from the point of view of logistics at beach.
Enjoy!
