Record number of tourists mean the RNLI is experiencing one of its busiest periods at the moment. The last few days at Perranporth Beach in Cornwall have seen a number of rescues some more serious than others.
Fortunately they've all had a positive outcome. Today most of their time was spent dealing with people who'd been stung by Weaver Fish.
Ninety five per cent of a lifeguard's work is preventative.
Two out of three people in the UK will head to the seaside at least once this year. The RNLI relies on public donations and legacies to maintain its service. Every year around 7,000 beach goers get into serious difficulties.
When most people are out enjoying themselves, these people are working, making sure everyone has another weekend to enjoy.
