Jumping into the sea at the 40 foot in Dun Laoghaire has become an annual event for many adventurous souls, both young and old.
And this year's December 25 managed to gather the crowds looking for a festive dip - not least due to the unseasonably mild temperatures.
There to keep the swimmers - including his mum - entertained was Ethan Philip Smith (6), from Sandycove, who was busy playing his new violin at the pier.
“I’ve been playing just since this morning,” Ethan told independent.ie.
“I got the violin for Christmas,” the Brian Kennedy fan, who is a student at Scoil Lorcain, said.
“I’m going to open the box and play and hopefully people put money for charity,” he added.
His mother Tara said it was the first time she had been at the spot to swim on Christmas, since his birth.

“It was lovely, the water was gorgeous,” she said.
Joan Fleetwood (62), from Blackrock, said she swims nearly every year on December 25.
“I usually do it for charity,” she said. “This year I didn’t want to ask. I was in for a minute or two,” she said.
Emily Reynolds (25), from Deansgrange and Kevin Spaulbing (23), from New York, also took a dip.
“It so warm I can’t even feel anything,” Ms Reynolds joked. Mr Spaulbing, who is in the US army, said he had been in the water at the spot during summer, but not at this time of year.
“It was ok,” he said.
