The RNLI is warning beach goers to heed lifeguards safety advice

The swimmers and surfers were pulled to safety by lifeguards at Perranporth and Perran Sands on Monday afternoon.

The RNLI said it was frustrating that holidaymakers regularly ignored warnings and swam outside safe areas.

Amy Caldwell told BBC News that lifeguards carried out risk assessments each morning and those going into the water should follow their advice.

She said the rip currents were caused by sand formations and deep gulleys on the beaches which are caused by a combination of the tides, surf and weather.

"As the tide comes into these deep gulleys, it's pulling people out of their depth," she said.

One experienced local surfer, Barry Smith, said people who ignored safety advice were putting others at risk and should be fined.

"I think it's about time they got to the point that parents are held responsible if it's children under age," he said.

"If they are adults, it's quite simple - then start fining them. They're putting other people at risk every time the lifeguards are out there."

Risk assessment

Ms Caldwell said the RNLI could only encourage people to take their safety advice to use lifeguarded beaches and swim in designated safe areas.

"Our lifeguards carry out risk assessments every morning which takes into account winds, tides and sea conditions," she said.

"We do it as a service so people feel confident that they can swim safely.

"But at the end of the day it's their choice - we don't have the powers to force them to swim between the flags."
