How to Cool Down Your Pool

Cooling off on a hot summer day is one of the biggest perks of pool ownership. However, in sunny states like Arizona, warm weather can quickly heat the temperature of your pool. Luckily, there are several ways to lower water temperature and cool down your pool so you can enjoy a refreshing swim all summer long.

Run Your Filter At Night

Running your pool filter at night helps cool down the water for several reasons. First, the air outside is the coolest at night, and cycling the water exposes it to colder temperatures. Water circulation also facilitates evaporation, which contributes to heat loss. Lastly, it is substantially cheaper to run your pool filter at night, encouraging you to run it for longer than you would during the daytime.

Use an Aerator

Another low-cost and easy way to cool down your pool is by installing an aerator. An aerator is an attachment that screws onto the side of your pool and sprays a fountain of water into the pool through the pump. The oxygen from the droplets spraying through the air can lower the water temperature by a few degrees, which makes a huge difference in the summer months. Aerators are a great option for states with dry climates like Arizona.

Shade the Pool Area

Shading your deck and pool area from direct sunlight will also help keep the water at a comfortable temperature. Landscaping features like trees, shrubs, and flowers can act as natural sun breaks. Airflow also naturally cools your pool through evaporation, so make sure to leave room for a breeze in your landscaping design. You can also install a canopy, sun shade, or umbrellas on the sunny side of the pool to help shade the water.

Invest in Active Cooling Mechanisms

Active cooling systems are some of the most effective ways to cool down residential swimming pools. There are two common forms: reversible heat pumps and evaporative coolers. While it seems counterintuitive, heat pumps are very effective at reducing water temperature. With the flip of a switch, they can cool your pool due to their reverse function that extracts heat from the water. They are a worthy investment if you also want to heat your pool in the winter.

As the name suggests, evaporative cooling uses evaporation to lower the temperature of your pool water. It is a more inexpensive option than heat pumps and is more practical for places that do not require pool heating. Pool owners can expect to see a 10-15 degree decrease in water temperature when they run these types of systems.

5. Install Water Features

Installing water features is both a fashionable and functional way to lower the temperature of your pool. Like a filter and an aerator, features like a fountain or waterfall keep the water circulating and increase air exposure, as well as encourage evaporation. These three mechanisms will work together to keep your pool water both active and cooler.
