On New Year's Day, people in certain countries gather on beaches and run into the water to celebrate the new year. In Canada, the Republic of Ireland, the United Kingdom, the United States, and the Netherlands this is very popular. These events are sometimes known as polar bear plunges, and are sometimes organized by groups to raise money for charity. Polar Bear Clubs in many Northern Hemisphere cities near bodies of water, have a tradition of holding organized plunges on New Year's Day.
