Jumping into the pool on a hot day is so refreshing, or at least you would expect it to be! Here in Florida, sometimes our pool gets so hot it feels more like a hot tub. Below, we’re sharing all the best ideas on how to cool pool water in summer.

How to Cool Pool Water in Summer: Best DIY Tips

How To Cool Pool Water in Summer

A pool is a great way to beat the summer heat, but not if the pool is just a large tub of hot water! Here are the best ways to lower your pool temperature for a refreshing swim on those hot Summer days:

Shade Structures:

Install shade structures such as umbrellas, pergolas, or shade sails around the pool area to reduce direct sunlight exposure and help maintain cooler water temperatures.

Here are some shade structures that cool the temperature of the pool water:

Water Features:

Incorporate water features like fountains, waterfalls, or misters into your pool design. The movement and evaporation of water can help lower the overall temperature of the pool.

Here are some water features to create flowing water in your pool:

Solar Covers:

Use a solar cover or blankets specially designed to reflect sunlight and prevent heat absorption in the pool water. These covers also reduce water evaporation, which helps to maintain cooler temperatures.

These solar blankets are great for controlling your pool’s water temperature:

Cooling Fans:

Place oscillating or misting fans strategically around the pool area to create air movement and promote evaporation, which can help cool down the surrounding air and water.

These cooling fans will help keep a comfortable temperature in and around your pool:

Ice or Ice Packs:

Add bags of ice or large ice packs directly into the pool water to lower its temperature quickly. This method is effective for temporary cooling but may require frequent replenishment. The other downside to this method is that it would take a lot of pounds of ice to make a difference in the pool’s temperature, which would be quite expensive.

Fountain Aeration:

Install a fountain or aerator in the pool to circulate the water and introduce air into the pool, facilitating evaporation and cooling.

This pool aerator can help cool a warm swimming pool:

Nighttime Operation:

Run pool equipment such as pumps and filters during cooler nighttime hours to circulate water and take advantage of lower ambient temperatures.

Water Exchange:

Partially drain and refill the pool with cooler water from a hose or other water source. Be sure to treat the new water appropriately to maintain water balance and quality.

Cooling Additives:

Consider using specialty products designed to lower water temperatures in pools. These additives may include natural ingredients or chemical compounds that facilitate heat exchange and cooling.

Adjustable Jets:

Utilize adjustable jets or nozzles to redirect water flow and create areas of increased turbulence, which enhances evaporative cooling.

Shade Trees and Landscaping:

Plant trees or shrubs strategically around the pool area to provide natural shade and reduce direct sunlight exposure, helping to keep the water temperature cooler.

Water Misters:

Install water misting systems or portable misting fans around the pool perimeter to spray fine water droplets into the air, which evaporate and create a cooling effect.

These misting fans are great for keeping a cool outdoor area:

Evening Swimming:

Schedule swimming sessions for the cooler hours of the day, such as early morning or late evening, to take advantage of naturally lower temperatures.

Reflective Pool Surfaces:

Choose pool materials and finishes with lighter colors or reflective properties to minimize heat absorption from sunlight.

By implementing one or more of these strategies, pool owners can effectively lower water temperatures and create a more comfortable swimming environment during the hot summer months.

Cooling Your Pool

Whether you have a fountain of water cooling your pool or a pool cooler, you will need to keep up with pool maintenance to be sure they are functioning correctly.  As you see above, there are many ways to keep your pool cool even in the hottest summer months. Running your cooler, fountains and waterfalls during the night time is a really effective way to cool down your pool as well. Plus, the cool night air will help balance out the temperature of your pool water.
