Winter swimming is the activity of swimming during the winter season, typically in outdoor locations or in unheated pools or lidos. In colder countries it may be synonymous with ice swimming, when the water is frozen over. This requires either breaking the ice or entering where a spring prevents the formation of ice. It may also be simulated by a pool of water at 0 °C (32 °F), the temperature at which water freezes.
