Summer in South Texas brings plenty of sunshine—but it can also bring pool water temps that feel more like bathwater than a refreshing retreat. While many pool owners focus on heating solutions, keeping your pool water cool during peak summer months can make a world of difference when it comes to comfort, safety, and overall enjoyment.
Whether you already own a pool or are in the planning stages, here are some smart and creative ways to help your backyard oasis stay cool all season long.
1. Add Water Features for Natural Cooling
Waterfalls, deck jets, and fountains do more than enhance the beauty of your pool—they also help cool the water naturally. These features create movement and aeration, which can bring water temps down by several degrees. The constant circulation introduces air into the water, helping to offset the heat absorbed during the hottest parts of the day.
At Copano Pools, we install custom water features like RicoRock® waterfalls that serve a dual purpose: visual impact and cooling function. Plus, there’s nothing quite like the sound of flowing water to add a relaxing, resort-style vibe to your backyard.
2. Consider a Pool Chiller or Heat Pump with Cooling Mode
Yes—pool chillers are a thing, and they’re becoming more popular in hot climates like ours. A standalone pool chiller is designed specifically to lower water temperatures. For those who already have a heat pump, many models include a cooling mode to help regulate temperatures in both directions.
If you’re a fiberglass pool owner, this can be an especially good solution. Fiberglass retains temperature efficiently, so a little cooling help can go a long way.
3. Add Shade Over Key Areas
Direct sunlight can quickly raise your pool water temperature, especially in shallow areas. Incorporating shade—whether it’s from a pergola, shade sail, or even thoughtfully placed landscaping—can provide much-needed relief for both the water and the people enjoying it.
Creating shaded zones also protects swimmers from sun exposure and reduces wear on poolside furniture and finishes. It’s a simple yet effective way to make your backyard more comfortable and functional.
4. Adjust Your Filtration and Circulation Schedule
Running your pool pump during the heat of the day can actually contribute to warmer water. Instead, try shifting your filtration and circulation to the cooler parts of the day—early morning or late evening. This not only helps prevent your pool from heating up but also improves water clarity and circulation.
It’s a small adjustment that can make a noticeable difference, especially during extended heat waves.
5. Choose the Right Pool Finish
If you’re still in the design or remodel phase, the interior finish of your pool plays a big role in temperature regulation. Lighter-colored finishes tend to reflect sunlight, helping the pool stay cooler. Darker colors absorb heat and can raise the overall water temperature.
At Copano Pools, we offer a wide range of fiberglass pool designs with finishes that balance aesthetic appeal with functional benefits—including heat reflection.
Cooler Water, Happier Swims
With a few strategic upgrades and design choices, you can turn your pool into a refreshing escape—no matter how hot the forecast gets. From water features and chillers to smart scheduling and shade, there are plenty of ways to keep your pool water comfortable all summer long.
