A man who died after he was swept out to sea has been named as Rudy Bruynius – as details emerged of a sixth sea death in 24 hours.familyPolice are urging people to be careful if they are swimming, sailing or walking near the edge of the water as the sea “can be extremely unforgiving with conditions changing rapidly”. Mr Bruynius was with his wife Lisinda and daughter McKayla on Cornwall’s Fistral Beach late on Friday afternoon when they were caught up by a large wave amid strong winds.

Lifeguards were alerted at 5.20pm and he was taken to hospital but later pronounced dead, while McKayla was reportedly in a critical condition. Two other children in the family managed to scramble back on to the rocks.

Five other people lost their lives during unseasonally treacherous weather conditions off the UK coast on Saturday. They included a windsurfer in his 60s who was rescued by lifeboats off the coast of West Mersea, but died in hospital and a man who got into trouble outside the safe swim area at Sandbanks in Poole, Dorset.

Six-year-old Lucas Walker died in hospital along with his 37-year-old mother Julie Walker after getting into difficulties in water at Aberdeen beach. A woman has died after getting into difficulty while swimming in Jersey ; the channel island’s coast guard received a call at 8.20pm and two boats, including one from the RNLI, were used to try and save the woman.
