What Temperature Should A Heated Pool Be

The ideal pool temperature is on average between 25 and 28°C. The optimal water temperature is thus about 10°C colder than the average body temperature.

Pool water that is too cold can cause hypothermia. If the water is too hot, there is a possibility of overheating.

What Temperature Should A Heated Pool Be

The pool in the garden is usually used in the summer months. The water temperature is increased either by the sun or by means of appropriate pool heating. But how warm should the pool water be?


The answer is – it depends because the optimal temperature in the pool depends on many factors. In any case, the pool or swimming pool thermometer helps to check how warm or cold the water is.


What Temperature Should A Heated Pool Be

The ideal range of a heated pool temperature is very wide. The feeling of warmth in one person may be too cold for another. For example, hot spring bathers prefer a water temperature of 40° C., Unlike ice bath participants who prefer a water temperature to freeze or lower.


Unfortunately, there is no scientifically perfect water temperature. However, it is necessary to pay attention to the water temperature, because it can have serious effects on health, whether good or bad.


According to experts, heated pool water temperatures typically run between 78 and 82 degrees. Any cooler than 78 and you will feel chilled when you exit the pool. Any warmer than 82 and the pool will feel like bathwater.


Determine Pool Water Temperature

To determine the optimal temperature for your pool you first need the current water temperature. If you like to go to your pool or swimming pool, an analog pool thermometer will do.

Provided with a line and afloat, an analog pool thermometer decorates the water surface. It does not require any energy sources and therefore requires little maintenance.


If you want to have the pool temperature in view everywhere, then there is a smart solution. For example, during your lunch break, you chat with your colleagues about what to do after work.

You spontaneously come up with the idea of swimming a few laps in the evening. But is the water warm enough? A glance at the WEATHERHUB app provides planning reliability.

The waterproof cable sensor measures the values in real-time and transmits them directly to the smartphone via a transmitter.


Those who like it technically simpler, but don’t want to forego comfort, opt for a digital pool thermometer. The outdoor sensor receives the water temperature values from the wireless sensor and sends them to the station in your living room.

What Is The Ideal Temperature For Swimming, Splashing, or Exercising?

Once you have determined the pool temperature, let’s look at what the ideal pool water temperature is. The ideal pool temperature depends on many factors:

  • Size of the pool: small backyard pool or a larger pool?
  • Bathers: Children, adults, seniors, or pregnant women?
  • Indoor/outdoor: indoors or outdoors?
  • Strength of use: many swimmers or few?
  • Type of use: pure splashing, relaxed bathing, swim training, or competitions?


There is no concrete temperature specification that takes all of these influences into account. Based on typical pool sizes and uses, we’ll give you temperature ranges based on your preferences.


Ideal Pool Temperature For Recreational Swimming Fun

The suggested water temperature for moderate activity is 25-28º C in the sun. The water insulates body heat so well that it doesn’t need to be much higher or lower than this. Most outdoor pools have a water temperature between 23ºC and 27ºC.


The optimal temperature for babies and children’s pools

Children and babies do not store much body heat due to their smaller size. The surface area of their skin is larger than that of adults and teenagers. This means they lose heat faster in a cold environment.

For adults, a pool with a temperature of 25.5° C can make you feel fresh. However, due to heat loss, children or babies may have blue lips and trembling teeth in a short time.

For the little ones, the water temperature must be much higher. Due to the small size, the water temperature of the children’s pool must be kept at 29-30°C.


Ideal water temperatures for fitness and training

Swimming is healthy. Performed technically correctly, you strengthen your body from the inside and outside. Almost all group muscles are used in swimming.

Muscles, tissues, cardiovascular and immune systems all benefit from regular swim workouts.

Warm water maximizes the endurance of the athlete’s body without compromising the system. When swimmers glide in the water, warm water can also reduce friction.

This, in turn, increased their speed. Therefore, during intense activities, pool water should reach a temperature of 26.5 °C.

When the water temperature is monitored and ideally set with the right thermometers, all you need is a stopwatch to measure your training times.


Ideal Water Temperature Chart By Activity

Here are the guidelines for the ideal water temperature for an ideal swimming experience at home in the pool or in a public pool:

  • Activity Water Temperature (Celsius)
  • Recreational swimming 25-28 °C
  • Children and babies 29-30 °C
  • Training and fitness 26.5 °C


Why Is An Optimal Pool Temperature Important?

It is a good thing to have your own swimming pool or hot tub: You can relax at any time of day or even night, splash around with friends or do circles on your own.

However, when it comes to water temperature, everyone is different. For various reasons, some may prefer a cool pool or a warm one.

But for the average swimmer, a water temperature of 25-27 degrees Celsius is comfortable in the summer. These water temperatures are low enough to prevent bacteria from nesting and the temperature is high enough to not be considered too cold.


How Warm Can Pool Water Be?

When pool water gets too hot, algae and bacteria find a comfortable environment to grow in the pool. This affects the chemistry of the pool. When you try to fight it, the chlorine runs low. Thus, the pH will be completely out of balance.


When Is The Pool Too Cold?

When the pool water is too cold, the body quickly starts to shiver. Even if the pool temperature is below 20°C, the blood vessels become extremely constricted.

When you bathe in this cold water, your breathing speeds up. These are reactions of the body to maintain body temperature. These reactions can cause cardiac arrhythmia in healthy people and cardiac arrest in people with heart problems.


Final Thoughts

Time for regeneration is just as important for health as exercise. This is also wonderfully possible at the edge of the pool or in the water. Summer is certainly not the only time there is an opportunity for a pool party.

No matter for what purpose you have your pool, with our pool thermometers bathing is a pleasure, because you monitor the values reliably with it.
