Kouremenos in East Crete, Greece is a fantastic place for windsurfing with strong wind blowing through the summer.  Best between June and September but May and October can have some good days too.  For equipment rental there is the "Freak Surf" windsurf centre with the latest JP boards and Neil Pryde sails.
