Naturally there are quite a few surf webcams around this area.
Fistral Beach in Newquay, Cornwall, is probably one of the most famous surfing beaches in the UK.
Fistral live via Headland Hotel Surfcam
If you don’t live in this area and you’re thinking about visiting then I can personally recommend.
update 2017 – not sure whats happened at Matts but their site appears to be offline at the moment.
