The World's Largest Swimming Lesson (WLSL), a global water safety event uniting waterparks, aquatic facilities, and community organizations across six continents, will mark its 17th annual event on Thursday, June 25, 2026. The event's singular purpose is to teach life-saving water competency skills and build awareness about the importance of teaching children to swim to help prevent drowning.

Why it matters

Drowning is a leading cause of death for children, yet millions of kids worldwide still do not receive formal swimming or water safety training. The WLSL aims to address this gap by providing kids and parents with exposure to life-saving skills and reinforcing layers of protection to keep families safer in and around the water.

The details

The 17th Annual WLSL event takes place over 24 hours, with participating facilities able to host special WLSL events or track and promote their regularly scheduled swim lessons that day. Registered facilities receive a comprehensive, turnkey Host Location Guide and a full suite of digital marketing materials. Last year's event drew participation from facilities across the globe, with Disney's Typhoon Lagoon Water Park and Dollywood's Splash Country Water Park hosting the largest numbers of participants.

  • The 17th Annual WLSL event takes place on Thursday, June 25, 2026.
  • The event happens just one week before the July 4th holiday — the deadliest stretch of summer for drowning incidents.
