Hi i am just starting to windsurf again, where do you all sail from and when ?

Hello....
Where people go from and when all depends on the wind direction and strength really... But probably your best bet for meeting up with people will be Castletown Bay or Derby Haven.

Other place people are likely to sail are Gansey if the waves are good, and couple of places along the NW coast such as Glen Wyllin or Ballaugh
