Worlds Largest Swimming Lesson (WLSL)

The World's Largest Swimming Lesson™ (WLSL) was created to raise awareness about the importance of teaching children to swim to prevent childhood drowning.  Since its inception in 2010, more than 383,000 children and adults have participated in WLSL Lessons in 53 countries on 6 continents. TEAM WLSL™ holds five Guinness World Records™.  

On Thursday, June 20th, 2024, an unlikely team of kids and adults at aquatic facilities all around the world will unite for the 15th year to teach kids vital water safety skills to help prevent childhood drowning.  The World's Largest Swim Lesson will take place over 24 hours at hundreds of aquatic centers, swim schools, and waterparks in more than 20 countries. 

Hangzhou International School's 'The Wave' will serve as an official Host Location Facility for the 2024 WLSL event. HIS was the first school in China to participate in WLSL and only one of two host venues in China in 2024.

Drowning is the leading cause of death for kids ages 1-4 and the second leading cause of unintentional injury death for kids 5-14, according to the American Academy of Pediatrics.  Drowning is the third leading cause of unintentional injury-related death worldwide. 
 
"We want to equip families with an understanding of the basic swimming skills and water safety knowledge they need to be safer in, on, and around the water," says HIS Aquatics Coordinator Natalio Liares, IV. "Knowing how to swim and prevent drowning is truly a matter of life and death for all families, regardless of race, economics or geography."
