Do you need a wetsuit to surf in Arugam Bay?

No, you really do not need a wetsuit to surf in Arugam Bay. The tropical Indian Ocean water stays warm pretty much the whole year; it averages around 27°C to 29°C, which is 81°F to 84°F.

A normal pair of board shorts, or a swimsuit in general, is enough for surfing there. Still, using a good UV-protective rash guard, basically a surf shirt, is highly recommended because the sun can be brutal, and it helps stop painful burns as well as the usual chest abrasions that come from surfboard wax. Some people also choose neoprene reef booties for the Main Point, mainly so their feet are protected from the sharp coral bottom when the sea floor is a little rough.
