Those intrepid islanders who like to celebrate the first day of spring with a plunge in the ocean are back in action on Sunday, September 1.

Anyone keen to brave the chilly water is invited to join in.

The group spanning generations will gather on the Cowes foreshore (in front of Isola di Capri) at 2pm for the big dip.

There's no official enrolments or formalities and you don't need experienced or advanced swimming skills to join in. It's not a fundraising event and is open to anyone willing to brave the icy waters.

There are no age restrictions and there are always plenty of kids willing to take the plunge.

However, there are three firm rules in place for the fun event: No wetsuits, no nudity and you must put your head under the water.

Last year, a breakaway group also hosted a Polar Bear jetty jump at San Remo.
