Nothing beats a dip in a cool pool on a hot day. But what happens if your pool is too hot?

No matter how well insulated your pool is, its temperature will fluctuate, especially if the temperatures outside remain hot and humid over a long stretch of time. While making the temperature go up is as easy as turning on your pool heater, cooling it down is a little more complex. 

The normal temperature range for residential swimming pools is around 78°F to 82°F (26°C to 28°C). If you notice that your pool has crept above that range and you are starting to feel uncomfortable in the water, use one of these techniques to cool down your pool.


How to cool down your pool


Fill your pool with ice

Do you have access to a whole truckload of ice? If so, this is technically the fastest way to cool down your pool. However, most people are not able to get enough ice to cool down their entire pool and the change is only temporary, making this method less practical. 

Re-think your pool landscaping 

The easiest way to keep your pool cool is to have air flowing across it. If your pool is blocked by trees, plants, furniture or fences, it can stop the normal airflow from reaching the surface of your pool. 

Adjusting your landscaping to ensure that airflow is passing over the surface of the water will do wonders for your pool’s temperature. 

Shade your pool 

Providing shade for your pool is another easy method to help keep your pool from getting too hot in the first place. There are many different ways to add shade over your pool, including planting trees or installing shade structures. Check out some of our favourite ways to shade an inground pool here

Install a reverse-cycle heat pump or an evaporative cooler 

Active cooling systems are one of the most popular ways to cool down residential swimming pools. There are two different types of systems:

The most common of the two is a reverse-cycle heat pump. This system can both heat and cool your pool which is ideal for homeowners in Vancouver, which experiences both hot temperatures in the summer and cooler temperatures in the spring and fall months. Keep in mind that these pumps consume a lot of electricity, so you should expect a higher energy bill.

If you are on a tighter budget, evaporative coolers might be the right option for you. Evaporative coolers are far less expensive than a reverse-cycle heat pump system and they are ideal if all you are looking for is the ability to cool down your pool. When installed properly, this system can usually reduce the temperature of a pool by 5 degrees, which should be more than enough in most cases. 

To install either of these systems in your pool, contact a professional Vancouver swimming pool contractor. 

Install a water fountain or waterfall

Adding a water fountain or waterfall to your pool will not only make your pool look nicer, but it will help keep your pool cooler as well. Moving water causes evaporation, which in turn helps to cool down the water. 

Run these mainly at night so that more water moves through the cooler air, which will help bring down the overall temperature of your pool. 

There are plenty of options to choose from so you can certainly find something that will help transform your pool into the perfect backyard oasis.

Utilize your pool cover when your pool is not in use

While covering your pool won’t necessarily lower your pool’s temperature, it will help prevent the water from getting warmer. Once you have properly cooled down your pool using one of the methods above, keep it covered whenever you are not using it in order to maintain the cool temperature, especially during hot sunny days. 


But how do you figure out which method for cooling down your pool is the right one for you? Choose the one that makes sense for your budget, needs and backyard.
