Located directly out from the entrance to Lake Illawarra, Windang is known as a big wave spot and has a great left down the southern side of the island, best in north-easterly to south-easterly swells and west to north-westerly winds. There is a patchy reef about 50m offshore on the northern side of the island, known as 'Sharkies'. This can produce good lefts and rights in most swell conditions, best in westerly to north-westerly winds. For experienced big wave surfers only.
