What is The Perfect Temperature For Your Backyard Pool?


What all people have in common is that we all love to swim and spend time in the water. That is why all those people who live in the coastal regions are considered happy and privileged, because in addition to having a pleasant climate, they have the sea or ocean for swimming almost all year round. But as swimming pools become affordable, you no longer have to live in coastal regions to be able to spend time in the water every day. It is enough to have a slightly larger yard and a few thousand dollars and you will be able to enjoy it whenever the weather is nice.

But what everyone has a different opinion about is what the ideal water temperature in the pool is. When we talk about the sea or the ocean, we know that we cannot influence the temperature of the water, but we know approximately what the temperature will be according to the time of year. The oceans are always cold, while the seas are quite warm. There is no universal answer to which temperature is ideal for pool water, so we will explain to you what is considered the ideal according to your wishes and needs. We will also tell you how to control the water temperature.

Why is it important?


There are several reasons why water temperature is so important. The first is of course that it is impossible to enjoy if the water is too cold or too hot. It can even be dangerous if you suddenly enter a pool that is too cold during the summer. This can lead to cardiovascular problems. It’s also not pleasant to feel like you are cooking in water instead of refreshing yourself. Another reason why it should not be too hot is that it will have an effect on the pH level and promote the growth of bacteria and algae that like a very warm environment.

Ideal temperature according to users of pool

For adults

If the pool is mostly used by adults for the purpose of resting, relaxing, and light swimming, it is ideally about 80 degrees Fahrenheit or 27 degrees Celsius. It is a very pleasant environment for the body, where the cardiovascular system will not be exposed to stress, and also our body will be pleasantly cooled on hot days. Under these conditions, algae and bacteria will not grow if you maintain the pool properly.

For kids


Various associations of pediatricians, including The American Academy of Pediatrics, recommend that the temperature of the water in the pool be warmer if children use it often. It is especially important for children under 10 years of age. Then it is recommended to be around 85 degrees Fahrenheit which is close to 30 degrees Celsius. It is very important to follow that guideline. We will explain to you why is that so. First, children should feel completely comfortable in the environment in which they find themselves maybe for the first time. If it is cold, they will want to get out as soon as possible and may develop an aversion to water. Then, warm water will relax their muscles, make breathing easier, and help them learn to swim more easily. So always heat the water so that your child develops affection for the water and swims without fear, which is the most important thing for safety.

For older users


The older people get, the less able their bodies are to withstand temperature changes. The main reason for this is that the cardiovascular system is no longer as flexible and heart attacks and similar problems can easily occur. Also, the skeleton is no longer as mobile as before and cold water will have a very bad effect on the joints and bones. Therefore, the water temperature should be the same as for children, maybe 1 degree Celsius warmer. It will be ideal for relaxing the skeleton and muscles and can have a positive effect on rheumatic and arthritic pain. Those who have arthritic and rheumatic pains will like even warmer water up to 33 degrees of Celsius. But it should not be very warm because it can cause heart problems.

For fitness

Aquarobics and other types of training in water are very popular and healthy. So they should be practiced if you have a pool. Since your body is additionally warmed during the workout, it is good for the water to be slightly colder, around 75 degrees Fahrenheit or 25 degrees Celsius. This will provide an ideal environment for the body to be able to withstand the entire workout without much effort. The water for water polo is even colder, so it’s clear to you that it’s good for sports activities.

How to measure it?


There are several ways you can measure water temperature. One way is to use a built-in thermostat in the heater, but this can be unreliable. The reason is that it will measure the temperature of the water around it, where it is warmest. That is why it is best to buy several thermostats and place them all over the pool. It is best to take smart ones, which will send data directly to your smartphone and you will always have a detailed report. The analog ones are out, while the infrared ones are too expensive and there is no need to spend money on them.

How to control temperature?


The answer is simple. You need a heater. Of course, the sun will act as a heater for several months of the year, but this is unreliable and if the summer is colder than usual, you may need a heater constantly. So you need it at almost every part of the globe. Also when you have a heater, the season of using the pool will be significantly longer. There are electric, gas ones and those that run on solar energy. Which one you choose will depend on many factors. You can find out more about each of them at and then make a best choice. What will further help you control the temperature and save electricity is the solar cover.


We believe that our detailed guide has helped you find the answer to one of the most common questions asked by every pool owner. And that is what the ideal water temperature is.
