Correctly understanding the pool water temperature is crucial for the comfort and health of the swimmers. According to the American Red Cross (ARC), the ideal pool temperature ranges between 77°F (25°C) and 82°F (28°C). Similarly, the World Health Organization (WHO) suggests the perfect swimming pool temperature ranges from 78.8°F (26°C) to 86°F (30°C).
This guide explores the perfect pool water temperature range for different users and covers various factors that affect your pool’s warmth. Let’s dive deep into your comprehensive pool temperature maintenance guide!
What are the factors affecting swimming pool temperature?
Following are some of the factors that affect pool temperature:
- Air Temperature
- Sun Exposure
- Wind
- Pool Size and Depth
- Pool Cover
1. Air Temperature
The surrounding air temperature determines the pool water temperature. For instance, hot surrounding air in the summer increases the pool water temperature. On the other hand, cool surrounding air contributes to cooler pool temperatures.
2. Sun Exposure
Sun exposure also impacts the pool’s temperature, especially in the summer. The more sun rays a pool water receives, the warmer it becomes.
3. Wind
Winds cause evaporation from the pool surface, creating a cooling effect. Stronger winds can lead to more rapid heat loss.
4. Pool Size and Depth
More extensive and deeper pools take longer to heat up and cool down than smaller and shallower pools because of their more significant volume of water to heat or cool.
5. Pool Cover
Pool covers can retain heat loss during the night and on colder days. It also helps prevent pool water from heating during warm weather conditions.
What is the ideal pool temperature?
The table below shows the ideal pool temperature based on the pool’s purpose and who is swimming in it. Additionally, you can adjust the temperature slightly based on personal preference, air temperature, and activity level.
| Features | Children | Adults | Athletes | Residential Pools | Hot tubs |
| In degree Celsius | 27.8-28.9 °C | 25.6-27.8 °C | 25.6-27.8 °C | 25.6-27.8 °C | 37.8-40 °C |
| In degree Fahrenheit | 82-84 °F | 78-82 °F | 78-82 °F | 78-82 °F | 100-104 °F |
How do I measure the pool temperature?
Generally, a pool pump thermostat is the most common way to measure pool water temperature. However, most experts do not recommend it because it gives an inaccurate reading as the water temperature changes from the heater to the pool structure.
The most effective way to measure your pool temperature is by using a pool temperature thermometer. Pool thermometers show the exact reading as they read the water temperature at the source. There are mainly three types of pool thermometers:
- Analog thermometers
- Digital pool thermometers
- Infrared pool thermometers
What are the benefits of a balanced pool water temperature?
The benefits of a balanced pool temperature are listed below:
- Safety and Comfort
- Prevent Bacterial and Algae Growth
- Water Balance
1. Safety and Comfort
The safety and comfort of the swimmers depend on who is using the pool water. For example, the comfortable pool temperature for children and athletes will vary. So, keeping the temperature balanced according to the purpose helps swimmers ensure safe swimming.
2. Prevent Bacterial and Algae Growth
Another benefit of maintaining water temperature is getting rid of pool algae and bacteria. Keeping the pool water at optimal temperature makes it inhabitable for algae and bacteria and prevents pool chemical evaporation.
3. Water Chemical Balance
A balanced pool temperature means a balanced pool’s chemicals. The pool’s pH, alkalinity, and chlorine/bromine levels work efficiently at optimal water temperature.

How warm is too warm for a pool?
We don’t advise swimming in a shared pool over 90 °F.
What is the ideal temperature for a pool in Knoxville and East Tennessee?
The perfect and average pool temperature for Knoxville and East Tennessee residents is between 78°F and 82°F (25.6°C and 27.8°C).
Is pool temperature the same as air temperature?
The pool temperature and the surrounding air temperature are not always the same. It takes your pool water 2-3 days to adjust to the average nighttime temperature.
What time of day is pool water warmest?
The warmest pool water is during the evening of the day.
How can I make my pool warmer quickly?
Turning the pool heater on is a quick way to make your pool warmer.
Wrapping Up
To conclude, swimming in a pool with a balanced temperature provides bodily comfort and is essential for swimmers’ safety. While the ideal pool water temperature may vary individually, a general idea about the perfect pool temperature range for children and residential pools should be kept in mind.
