NATIONAL POOL OPENING DAY - Last Saturday in April

NATIONAL POOL OPENING DAY – Last Saturday in April


Each year on the last Saturday in April, National Pool Opening Day encourages pool owners across the country to prepare their swimming pools for a summer of fun, fitness, and enjoyment.

Swimming pools offer many benefits including physical exercise, social interaction and psychological benefits. Exercising in a swimming pool allows us to do many things that are difficult on land. The water makes us buoyant, so we don’t put as much strain on our joints. It also creates resistance, so every move becomes more of a workout. Another benefit is the cooling effect of water. It helps prevent overheating while exercising. Socializing at the swimming pool can be relaxing and fun. It can help relieve stress while enjoying friends and family.

HOW TO OBSERVE #PoolOpeningDay

Test and balance your water to ensure it is healthy and safe. Check your pool equipment for proper operation. Get out your favorite pool accessories so you can fully enjoy your pool. Post photos of you and your family enjoying your pool on social media using #PoolOpeningDay.


In 2016, Leslie’s Swimming Pool Supplies founded National Pool Opening Day to celebrate that first cool dip and to encourage everyone to make their pools as safe and clean as possible.

The Registrar at National Day Calendar proclaimed the day to be observed on last Saturday in April, annually.
