The three main beaches at Falmouth - Maenporth, Swanpool and Gyllyngvase - can break when an Atlantic storm rolls through or when a solid southwesterly swell marches up from the Bay of Biscay. Between Swanpool and Gyllyngvase there's a rocky protrusion called Falmouth Reef that can produce long, walling rights. Large local surf population supplemented by the Uni students so will be busy if breaking.
