Sunrise Swim for Lakes -Join us on first World Lake day 27 August

On 27 August, SIWI and World Water Week will celebrate the first United Nations World Lake Day with an early morning swim in central Stockholm. The event highlights the vital role of lakes and urban waterways in climate action, biodiversity, and community wellbeing.
Why lakes matter
Lakes are among the most important freshwater systems on Earth. They regulate local climates, store carbon, and support rich biodiversity. They also provide drinking water, food, recreation, and cultural value. But these benefits are at risk: lakes are shrinking, becoming polluted, or disappearing altogether at a pace that is alarming.
In cities, lakes and rivers also represent something more. The idea of a swimmable city is not only about water quality – it is about ensuring that all people can access and enjoy shared water resources. Lakes and waterways can connect communities, create healthier urban environments, and remind us that water is both a basic need and a shared responsibility.
From conference to shoreline
To mark this new UN day called World Lake Day, World Water Week participants will step out of the conference halls and into the water. Starting at the Stockholm Waterfront Congress Centre, the group will head to Marieviksbadet for an early morning swim. It is a symbolic but powerful way to show that protecting lakes requires action beyond discussion – it demands visible commitment and a connection to the water itself.
A global call to action
World Lake Day is both a celebration and a warning. It draws attention to the many ways lakes sustain life and prosperity, but also to the urgent need to safeguard them. By joining the swim, participants help underline that lakes must be protected for people, nature, and future generations.

All are welcome to take part in the swim on 27 August – just bring swimwear, a towel, and your passion for water.
