What is ice swimming?
Ice swimming is swimming in water at a temperature of 5°C (41°F) or lower, unassisted, with a silicon cap, pair of goggles and standard swimming costume. The International Ice Swimming Association (IISA) has established a comprehensive set of safety and swimming rules together with worldwide swim records. IISA has members in 73 countries, including IISA Aotearoa New Zealand.
Ice swimming is a growing sport in Aotearoa New Zealand. In 2023 and 2025, we sent a highly competitive national team to compete at the World Ice Swimming Championships, who brought home world championship medals and world records.
