Turkeys, knights of old and even an oven were just some of the festive fancy dress choices by those taking part in outdoor swims on Christmas Day.
Plucky bathers took to the sea off Dorset, Devon and Norfolk as well as the Serpentine lake for the traditional Peter Pan Cup race in London's Hyde Park.
Sea surface temperatures across the country were between 8C and 11C, the Met Office said.
The race in the capital is believed to be the world's oldest continuously contested swimming competition, having been run since 1864.
