Around 40 bathers took the plunge and met at sunrise for the annual New Year's Day morning sea swim from the beach at North Shore.
Some of the swimmers were organised by Paul Ogden and featured members of the Wild At Heart Facebook page, who regularly swim on the River Witham at Tattershall Bridge..
Members of Boston Bluetits and Skegness Triathlon Group also took part.
Mark Deith was onshore taking the pics and said conditions were ideal, with a relatively flat sea at around 8C and air temperature 5C.
Michyla Clark, of the Skegness Triathlon Group, commented: “It was very refreshing!
“There were more swimmers this year than I’ve ever known before.”
Anyone interested in open water swimming can seek details from the local 'Wild At Heart' Facebook group.
