Northeast-facing headland on the leeward coast taking along-channel west-northwest energy at high strength and westerly wind chop at moderate strength. Rare north through northwest swell arrives at full to high exposure, keeping the point surge-prone in winter. South through southwest energy is heavily shadowed by the island, with only a weak residual reaching the wall. Strong down-currents can occur near the point.
