In the sweltering summer sun, pool water can reach temperatures of 90 degrees Fahrenheit or above. While a pool can be a cool respite from the heat, hot swimming water (similar to a hot tub) is undesirable for most people. Thankfully, there are several quick-and-easy ways to lower your pool temperature this summer. Read on to discover some suggestions below.

Cheap and easy, these attachments plug or screw into the side of your pool. They work by using return water from the pump to spray a fountain of water back into the pool. These tiny droplets of water have air in them as they are sprayed, allowing heat to escape more quickly by evaporation. If your pool temperature is at 94 degrees Fahrenheit, for example, you can expect it to decrease to roughly 90 degrees Fahrenheit with an aerator installed.

Fountain and Waterfall
Similar in concept to an aerator, these water features lower temperature by increasing air bubbles, thus encouraging evaporation. Decorative in appearance, these can also increase the value of your pool area by a few notches by improving the overall aesthetic.

Evening Pump
Running the pump at night will amplify the effects of aerators and fountains. The cooler temperature drop in the air will help to lower the water temperature more efficiently when the sun isn’t working against you. Even without an aerator or fountain, running the pool pump overnight will help circulate the water and release some heat into the cool evening air.

Solar Panels
While these are primarily purchased to heat a pool, they can also be used to cool water temperatures. Instead of letting water pass through the panels during the daytime, use them while running the pump at night to take advantage of the lower temperatures. Solar panels can be used in addition to other methods listed to further enhance cooling effects.

Pool Coolers
These dedicated “air conditioners” for your pool transfer heat with help from fans and refrigerants. Once cooled, the water is then pumped back into the pool. Most pools change between 10 to 15 degrees after a pool cooler is used. Temperature controls are useful to find the perfect comfort level.

A tried-and-true method of staying cool and out of the sun, shading a pool typically involves tall trees. Unfortunately, those trees are also associated with extra cleaning issues such as tree debris (leaves, pollen, etc.) that might fall into the water. Other options for shade include canopies or another physical structure that provides shade over the pool.
