I kitesurfed the main surf break once, bit schetchy getting into the wave and then even worse getting out after the locals did not take kindly to a kitesurfing dropping in on that sweet left hander.
Irony is the days when it was not windy, I surfed it no problem.
And before anyone rabble on, it was blowing 30 knots and I still gave them priority on every wave.
Was really good there though

Otherwise in the main estuary you can kite or outside the harbour if wind is right.
