Usually best in Jan, Mar, Dec.
Sennen sits in Whitesand Bay, the last stop before Land's End. It faces west into open ocean with nothing to block the swell, so it often has waves when the rest of the north coast is flat. That makes it the summer go-to for a lot of west Cornwall surfers.
The bay changes character along its length. Near the harbour the waves are smaller and gentler, which suits learners, while the middle and the Gwynver end to the north pick up more power. An east wind is offshore. On big winter swells it can get heavy, with long hold-downs and currents that pull hard along the beach.
Boots from November to May, plus gloves and a hood when the sea drops below 10°C.
Sennen is a beachbreak in Cornwall, England. It suits beginner, intermediate and advanced surfers.
