What is the Perfect Pool Temperature?

Perfect Pool Temperature: Nothing beats a bath on a hot day. But what if your pool is too hot for comfort, or worse, hot enough for bacteria, algae, and other microbes to start growing? What if you dive in too hard, your breathing stands hampered, and your skin feels on fire? The faultless pool temperature is more important than you think.

Why Pool Temperature Matters

Having your pool temperature fluctuates with the outside temperature is not a good idea. Temperature is an essential factor for all living things. It includes creatures that want to live in pools.

Hydrothermal Pollution

Hydrothermal Pollution

Specifically, we are talking about heat-loving microorganisms called algae and bacteria. Algae are microscopic organisms that perform photosynthesis. Algae is alive in the pool if a green film covers the collection or if green, yellow, or brown clumps remain scattered throughout the water.

A Michigan State University report found that algae significantly contribute to fouling in pristine pools but can make bathers itchy, give collections an unpleasant odor, and clog water filtration systems. Yes. Bacteria can similarly cause problems in your pool. Although less noticeable than algae, bacteria are more susceptible to disease than algae.

The MSU report states, “Bacteria found in swimming pools are generally risky and should remain controlled. Certain bacteria produce poisonous substances that can cause diseases such as tetanus and food poisoning in humans.

Cold Water Hazards

Cold pool temperatures create problems in addition to hot difficulties. The National Cold Water Safety Center says water temperatures below 78 degrees Fahrenheit can affect a swimmer’s breathing. This is especially correct for those with limited respiratory function, such as B—people with COPD and asthma.

As the temperature drops from her 70°F to 60°F, the swimmer becomes increasingly difficult to breathe. It’s not comfortable at primary, but your body gets used to it.

Jumping into a 50°F to 60°F pool is dangerous. However, according to the National Center for Cold Water Safety, unless she swims in freezing cold water for long periods, an unacclimated body will treat water temperatures between 50°F and 60°F as she does at 35°F. to handle.

Breathless and Hyperventilate

Such cold water can cause complete loss of breath control, causing swimmers to become breathless and hyperventilate. In addition, the body also receives a cold shock. It prevents them from swimming effectively and increases their chances of drowning.

Jumping into a 40°F to 32°F pool is a pain. In addition to being unable to breathe or swim, the skin becomes extremely cold, like heat. It touches like your skin is on fire. It takes 8-12 hours for the pool to acclimate to the outside temperature. For example, if you or your child jump into the pool at 3 pm, the temperature is 80°F, but overnight temperatures can reach 40°F and cause swimming injuries.

Pools used for physiotherapy also need to be hot, ideally around 30°C. The warmer temperatures also help swimmers relax their muscles and make stretching easier.
Small children need warm water. According to the Red Cross, the temperature of an infant or preschool child’s pool must be between 90 and 93 degrees Fahrenheit.

Olympic Pools

A slightly cooler pool temperature is suitable for sports and swimming training. Olympic pools are kept at 27-26 degrees Celsius, allowing swimmers to stay cool for hours without affecting their breathing.

As you can see, the model temperature range for a pool depends on what it remains used for. But as a general rule, keep it around 77°F to 84°F. One of the most unswerving ways to measure pool temperature is with a pool thermometer.

Many pool thermometers float on the surface and read the temperature consistently in the pool’s center. Some pool thermometers use alcohol on a numeric scale to display pool temperature (called analog thermometers). Other pool thermometers use an LCD screen to display an accurate temperature (digital thermometer).

Other pool thermometers are wireless. You can place a component in a pool, measure its temperature, and send the data to another device that displays the pool’s temperature. Those who don’t dare bend over to get a pool thermometer will find the wireless version practical.
Some pool thermometers, such as analog thermometers, require no power. Others use the sun to power their shades. Others use batteries to tell the time. Which thermometer you get should be a matter of preference, as each has its pros and cons.

How to Control the Temperature of the Pool. The best way to control the pool temperature is to use a pool heater. These pumps have a built-in thermostat to measure the temperature of the pool. Then adjust the pool’s temperature to the desired temperature,  like an air conditioning system.

The pool pump will run until the desired temperature remains reached. Then the switch is turned off and on again when the water temperature deviates by more than 2 degrees.


Some pool pumps also have a timer function. You can set the clock to turn on the pool heating or cooling to reach your desired temperature when you are most likely to swim. The timer can also save energy by turning off the pool pump when swimming is less likely in the middle of the night.
