What’s the Best Pool Water Temperature

According to the American Red Cross (ARC), a leading authority in aquatic safety, pool water temperatures ranging from 78°F to 85°F are generally considered comfortable and safe for swimming. This temperature range is designed to accommodate various swimming activities and user groups while striking a balance between feeling refreshed and avoiding discomfort from excessively cold water.

Similarly, the World Health Organization (WHO) recommends a water temperature range of 78°F to 86°F for individuals engaging in moderate physical activity within a pool environment. This range supports physical exertion without causing undue stress or discomfort.

Many recreational swimmers find water temperatures between 77°F and 82°F to be optimal, offering a refreshing experience without feeling too chilly, particularly for adults engaged in casual swimming.
