One of the best turn-outs saw 175 people dash into the sea at Hunstanton for the annual Christmas Day swim.
Organised by the town’s Round Table the traditional event is set to raise around £5,000 for charity.
This year’s swim was held in memory of Heacham man Sean Sands, who died last year in a kite-surfing accident off the beach.
The father-of-three had always supported the swim.
Thousands turned out to watch this year and Round Table spokesman, Andrew Searle, said it was a fitting tribute to Mr Sands.
“There was really strong support for the day,” he said.
Most of the money raised will go to the RNLI and the East Anglian Air Ambulance as charities chosen by the Sands family and the remainder will go to local causes.
