What is the “ideal” temperature for swimming?
This decision is really up to the pool owner, since some people like their pools warmer than others do. The American Red Cross recommends a water temperature of 78° Fahrenheit for competitive swimming. However, this may be too cold for young children and the elderly. The typical pool temperature range is 78°-82°, although most recreational swimmers enjoy 82°-84°. Something to think about: Depending on your location and the time of year, raising the pool’s temperature by one degree can increase your energy consumption by 10-30%. If you like your water warm, consider adding a solar cover and a solar heating system to your pool’s heater.
