World’s Largest Swimming Lesson marks 17 years of saving lives
Global safety and skill-building event returns on June 25
Overland Park, Kan. — Launched in June 2010, The World's Largest Swimming Lesson (WLSL) is a global water safety event uniting water parks, aquatic facilities and community organizations across six continents. Its singular purpose: teaching life-saving water competency skills to help prevent drowning and building awareness about the vital importance of teaching children to swim.
The 17th Annual WLSL event takes place on Thursday, June 25, 2026, over the course of 24 hours. Coordinated by the World Waterpark Association (WWA), the event happens just one week before the July 4th holiday — the deadliest stretch of summer for drowning incidents. Statistics from the Centers for Disease Control and Prevention, National Center for Injury Prevention and Control WISQARS, show that nearly 17% of all U.S. drownings occur during July, with risk peaking in the days surrounding the holiday.
“Every child deserves the safety that basic swimming skills and layers of protection provide,” said Rick Root, president of WWA. “What started as a bold idea 17 years ago has become a shared mission that spans the globe. When facilities from dozens of countries come together on the same day for the same cause, it sends a powerful message to families everywhere that learning to swim saves lives."
The human toll of drowning is staggering. The American Academy of Pediatrics reports drowning as the leading cause of death for children ages one through four, and the second leading cause of unintentional injury death for children ages five through 14.
Research shows that participation in formal swimming lessons can significantly reduce the risk of drowning among young children, yet millions of kids worldwide still do not receive formal swimming or water safety training. The WLSL addresses that gap directly, providing kids and parents with exposure to life-saving skills and reinforcing layers of protection to keep families safer in and around the water.
For participating facilities, the WLSL is more than a community service event — it’s an opportunity to showcase their team’s commitment to the people they serve. Staff members frequently cite the event as a season highlight, bringing energy and pride to their work as they see firsthand the impact of what they do every day. Facilities gain visibility, strengthen ties with local families and nonprofit organizations, and demonstrate their role as a cornerstone of water safety in their communities. Many venues use the event to welcome first-time visitors and introduce new audiences to their programs.
All types of aquatic facilities and learn-to-swim providers are welcome and encouraged to register. Local WLSL events take place at water parks, pools, aquatic centers and beaches. Facilities can create a special WLSL event or participate by tracking and promoting their regularly scheduled swim lessons that day. Registered facilities receive a comprehensive, turnkey Host Location Guide and a full suite of digital marketing materials, including logos, posters, flyers, web banners, press releases, social media graphics, day-of-event materials and curriculum.
Last year’s event drew participation from facilities across the globe. Since its inception, the WLSL's message has generated more than $37 million in earned media in the U.S. alone.
Registration starts at $99 per facility, with discounts available for operators hosting the event at multiple locations.
