An annual post-Christmas tradition has taken place at coastal resorts across the north-east of England.
Hundreds of people of all ages, many in fancy dress, have had a dip in the North Sea to raise money for charity.
Whitley Bay, Newbiggen and Redcar were among those hosting the events, which also proved popular with spectators.
More than 1,000 people took part in a mass dip at Seaburn, near Sunderland, thought to be one of the largest in Europe, and now in its 36th year.
Cheered on by thousands of spectators, it raised almost £70,000 for the Help for Heroes charity.
In Redcar, about 100 people took to the waves, in an event benefiting a number of charities, including the RNLI.
Dave Cocks from Redcar RNLI said: 'We are always amazed how many people brave the cold North Sea to raise money for charity.
"The costumes are fantastic and there were dippers of all ages in the sea today. Well done to them all."
