What Is The Ideal Temperature For A Pool?


Keeping your swimming pool at the optimal temperature all year round can be challenging. Despite many methods claiming to help solve this problem, it may not be as harmful as initially thought. In fact, there are benefits to having the pool slightly too hot or slightly too cold. But what are these advantages? Does the pool type affect the water temperature? Shenling is here to assist you anytime.


What happens if my pool temperature is too high?

Having a warm, heated pool may seem like a luxury, but it can become a breeding ground for bacteria and algae. It can also affect the chemical reactions in the pool. Maintaining water balance is crucial to ensure swimming safety.


Depending on its purpose, competitive swimmers may prefer cooler water temperatures, while young children and older adults may benefit more from warmer water. However, it is said that the ideal average pool temperature for everyone is between 77-82°F (25-28°C). These temperatures are low enough to prevent bacterial growth yet warm enough to ward off the chill.

How to lower the temperature:

Add waterfalls or fountains to the pool: The action of water will cause evaporation, cooling the pool water.

Partially drain and refill the pool: This method is effective, but you need to rebalance the water’s chemical composition.


Provide shade for your pool: Try adding patio umbrellas or planting trees around the pool area.

Use a reversible heat pump: A simple switch can heat or cool the pool water.

Regularly test and treat your pool water: This prevents algae and bacteria growth, keeping the pool safe and clean.

Run your pool water pump for an adequate amount of time: Typically, run it for about 8-12 hours per day.

What happens if my pool temperature is too cold?

Lower temperatures can have serious effects on our bodies. While cold showers have some health benefits, they also come with certain risks. According to the National Cold Water Safety Center, pool water below 50°F (10°C) can lead to various issues, including:

  • Lack of breath control
  • Shock
  • Lack of concentration
  • Pain

Even temperatures below 77°F (25°C) can affect swimmers’ breathing. Water below this temperature should only be used by competitive swimmers under close supervision.

How to increase the temperature:

Make the most of sunlight: Sunlight is a natural way to heat the pool, especially during the rising temperatures of summer. This method is efficient and environmentally friendly. Therefore, trim excess leaves around the pool and position patio umbrellas strategically.

Install a heater: If your pool is not exposed to direct sunlight, this is a perfect alternative. Heaters are efficient, economical, easy to use, and durable, making them an ideal way to heat the water.

Cover the pool when not in use: While this method won’t actively heat the pool, it helps retain the heat already generated. Simply cover the pool when not in use to slow down water cooling. This can also help reduce your energy costs.

Advantages of a heated pool:

A heated pool can provide you with year-round enjoyment and happiness – this is one way you benefit from a luxury heated pool. Other advantages include:


It won’t suffer from freezing conditions: Without heating, the pool could sustain damage due to low temperatures. The pool pump, surrounding pipes, or pool tiles or lining may crack and eventually warp due to temperature fluctuations, especially if you empty the pool before winter starts.

Additional health benefits: Swimming is an excellent way to stay healthy, and a warm water pool will motivate friends and family to use it. Warm pools are also great for older individuals, especially those with muscle or joint issues. Young children will also find swimming in it more comfortable.

It provides a pleasant, enjoyable swimming experience: A warm water pool offers a level of comfort unmatched by a non-heated pool. It allows you to relax and enjoy the pool at any time of the year (day or night). So, whether you’re joining a pool party late at night or taking a refreshing swim on a crisp autumn morning, you can freely do what you want in a luxurious heated pool.

Advantages of a cool pool:

A cool, non-heated pool can provide several benefits, improving your health and keeping you active without feeling too cold. Other advantages include:


Boosting your immune system: Cold water has been shown to increase our white blood cell count. This is because our bodies are forced to react to constantly changing temperatures and conditions. This makes your body more efficient at activating its defense mechanisms, thus strengthening your immune system.
Improving blood circulation: Cold water causes blood to flow towards the surface, helping to warm our extremities. Immersing in cold water can improve our blood circulation as it flushes out our veins, capillaries, and arteries. With repeated exposure, we adapt to colder temperatures more easily.

Aiding calorie burning: When exposed to cold, our heart beats faster to keep our body warm, especially while swimming in cold water. The rate at which our body stays warm will result in burning more calories while exercising.

Reducing stress: Cold environments can bring mental and physical stress to our bodies. However, research suggests a specific link between swimming in cold water and reducing stress. This might explain why cold-water swimmers often appear calmer and more relaxed during exercise.
