Among Saundersfoot's record-breaking dippers on New Year's Day were the family and friends of Brian and Lilian Lang, of Edgecombe House.
The 12-strong group flew the Welsh, English and American flags as they took the plunge in their pink costumes.
They were raising money for the Sea View Hostel at Singleton Hospital, Swansea, where cancer patients from Pembrokeshire, Cardiganshire and Carmarthenshire, can stay while they have their three to four weeks radium treatment.
"This hospital is the nearest for this kind of treatment and the hostel has been set-up for those who find it too far and particularly tiring to travel backwards and forwards each day," said Mrs. Lang.
"The hostel lacks a lot of home from home comforts which is particularly needed for anyone staying so long away from home so the money the swimmers raised is going towards puchasing extra items for the facility."
Among the group were daughter and son-in-law Denise and Dai Roberts and their children Laura, Charlie and Tom who had travelled 'home' from the USA for the New Year.
The Saundersfoot dip was, however, not the first time the quintet had braved chilly waters over the festive season.
For Dai, a former Tenby plunge veteran, is the organiser of the now annual Boxing Day Virginia Beach swim.
Now in its ninth year, the parade of flags and swim attracted 32 bathers and a crowd of 60/70 spectators. All dippers duly received medals courtesy of Tenby Sea Swimming Association.
"It was just as cold in Saundersfoot as it was in Virginia," said Mrs. Lang.
"The family haven't been home for a couple of years and they thought the swim was absolutely marvellous and they had a lot of fun.
"They have now taken some ideas back which they hope to develop for their 10th anniversary swim on Boxing Day," she added.
As well as the family from the States, the group included friends and family from Saundersfoot and family from Crawley.
