One hundred people took part in the annual Golden Sands Polar Bear challenge in Whitehaven to raise £25,000 for charity.
The dippers ran into the Irish Sea in the harbour town and straight back out again.
Most we wearing fancy dress or t-shirts bearing the name of their chosen charity.
The annual dip is organised by Sellafield workers.
"We were treated to a warm up by the Moky Fit girls and then cooled down dramatically in the sea.
"This is a great way to raise money for charity and it does seem to be getting bigger and better every year.
"It's brilliant to see so many people get into the spirit of the occasion and dress up - a different way to say goodbye to the year."
