Newhaven Lifeboat was urging people to take extra care when on the beach today (Monday December 23) due to the stormy conditions.
Teenager Dylan Alkins was tragically swept away to sea from West Beach in Newhaven in October during rough weather.
And a woman was swept away by the sea in Brighton on Saturday December 21 when she ran into the water at 2.30am.
She had left a seafront night club and was walking along the beach between West Pier and Palace Pier with a man she knew.
When she entered the water she was almost immediately swept off by a large wave.
The man tried to grab her but was unable to drag her to safety.
Police arrived within minutes and together with club staff and her friend approached the sea but the woman was being washed further away and was inaccessible due to the very heavy sea conditions.
Coastguards assisted the search by land and sea, together with the RNLI All-Weather Lifeboat based at Shoreham, but the body has not so far been recovered and the immediate search has been discontinued at this time.
Her reason for running into the water is not clear at present but the incident is not being treated as suspicious.
A spokesperson for the Lifeboat said: “With bad weather and very rough seas predicted for later today, please take extra care if you are on the beach, it can only take a second to be caught out and get swept away.
“Stay safe and don’t make it a tragic Christmas.”
