A Devon GP, who is also a keen surfer, has urged other surfers to stay at home amid fears it will send the wrong message to others.
Webcams at popular beaches in North Devon appeared to show at least 20 surfers in the water.
It comes after the Prime Minister issued guidelines on which people can and can't leave their homes during the partial lockdown.
The exact wording of the Government advice states that people can go outside for "one form of exercise a day, for example a run, walk, or cycle - alone or with members of your household".
Some surfers have argued that surfing is a form of exercise, carried out alone which can easily be conducted at a distance of at least two metres away from other people.
But others say the Government's rules are designed to keep people at home and stop all non-essential travel and they say that should include surfing.
North Devon GP and keen surfer Dr Finola ONeill said although she loves the sport, she would urge everyone to stay indoors at the moment.
