Since 2020, the Gdynia Winter Swimming Cup has brought winter swimmers together in the heart of Gdynia Marina. What started as a local event has grown into an international competition, hosting the International Polish Winter Swimming Championships and becoming part of the IWSA World Cup for three consecutive years.

In 2027, GWSC takes the next step: Gdynia will host the first-ever IWSA European Championships, welcoming winter swimmers from across Europe to the Baltic Sea.

From the very beginning, GWSC has been connected with charity initiatives supporting Ronald McDonald House Charities and its mission to help families of children undergoing hospital treatment.
