It's a bit too onshore at Mt Martha and Safety Beach ,but having said that Safety Beach sometimes works when the wind (northerly) is too light everywhere else. It seems to me the wind is up high, hits the Mt Martha hill and runs down onto the water, forming a pocket of wind at the marina end. It's better on a board which you can uphaul because if you go too far out you lose the wind and don't get it back. It's a bit gusty but the water state is real good for the bay.
