A spokesman for the RNLI said: “Tragically there have been several fatalities reported from around the UK coastline this year, including these recent incidents in Worthing.

“We urge people to please respect the powers of the sea and would encourage anyone taking part in offshore activities to please be aware of the weather conditions and use all the safety equipment available to them.”

Cllr Vicki Wells, Worthing’s Cabinet Member for the Environment, said: “Our thoughts are with the families and friends who have lost their loved ones under such heartbreaking circumstances.

“I would like to thank members of the public for their assistance in calling the emergency services, our Coastal Office team, coastguards and volunteer RNLI crew who attended.

“We want everyone to enjoy a safe trip to our seaside and urge everyone to follow the advice provided by the RNLI.”

People heading to the beach or out to sea are also encouraged to ensure their phone is charged, so they can call for help or support someone who might need assistance.

If you require help at the beach or on the water, call 999 and ask for the Coastguard.
