What Is the Average Pool Temperature?

Most recreational swimmers find the right temperature to be between 77 and 82°F.

A common comfort point is about 85°F, which balances relaxation, safety, and accessibility for a wide variety of activities.

  • Recreational swimming: 78–82°F
  • Adults: 85–89°F
  • Children and elderly: 84–94°F
  • Competitive swimmers and fitness: 77–82°F
  • Therapy pools and rehab: 90–92°F

This swimming pool temperature range helps maintain comfort while supporting health and energy efficiency.


What Are the Best Pool Temperatures by Activity?

Recreational Swimming

For casual swimming, the ideal pool temperature is 78–82°F, which feels just right on hot afternoons in Fuquay-Varina.

Pools used for swimming lessons are often kept warmer, around 86–88°F, so beginners feel more comfortable.

Younger children between 3 and 5 years old do best in warmer water between 86 and 90°F, while older children between 6 and 13 years old are comfortable around 84–86°F.

Fitness and Competitive Swimming

For competitive swimming, the desired temperature is generally cooler, at 82°F or slightly lower.

Aerobic lap swimming and high-intensity workouts are most effective in 78–82°F water and are usually performed in rectangular-shaped rather than free-form pools.

Cooler water prevents the body from overheating during extended exercise sessions.

Aquatic Therapy and Special Use

Therapy pools and rehabilitation programs work best in warmer temperatures between 90 and 92°F.

This range supports circulation, reduces joint pain, and makes movement easier for recovery or medical needs.

Warmer water is especially helpful for elderly swimmers, infants, or those managing health conditions, but water should not exceed 95°F for safety.

Adults

Most adults enjoy swimming when the pool temperature is between 85 and 89°F.

For fitness or exercise, a cooler water range of 78–84°F is often best to prevent fatigue and overheating.

Seniors

Seniors are most comfortable in warmer water, with a swimming pool temperature between 84 and 94°F.

Warmer water is suitable for gentle exercise, relaxation, or low-intensity activities that reduce joint stress.


How Air Temperature Affects Comfort

Air temperature plays a major role in how pool water feels.

The air should generally stay within 2 to 4°F of the pool temperature.

For example, if a pool is set at 86–88°F, the air around it should be kept between 82 and 84°F for comfort.

During high-intensity swimming, slightly cooler air between 78 and 80°F helps prevent overheating and keeps swimmers comfortable.


Finding the Perfect Balance for Your Pool Temperature

Since most pools are used for a mix of recreation, exercise, and family fun, finding a balance is important.

Many pool owners set the water temperature at about 85°F because it is a good middle ground for most uses.

Warmer temperatures tend to be more enjoyable for children and casual swimming, while cooler water is better suited to competitive swimmers and exercise.

Adjusting the temperature setting depending on the group or activity is the best way to keep everyone happy.


Energy Efficiency and Heating Costs

Efficient Operating Range

Raising pool water above 82°F increases heating costs significantly.

Each degree higher can raise energy use by 10 to 30 percent.

Balancing comfort with efficiency helps keep your swimming pool more affordable to run.

Energy-Saving Tips

  • Use solar or thermal covers to reduce evaporation and heat loss by 50–70%.
  • Consider using a pool heater powered by solar energy or a heat pump for sustainable warmth.
  • Program your pump and pool heater to run only when needed to stay energy efficient.

Frequently Asked Questions

Is the ideal temperature different for a saltwater pool?

No. Saltwater and chlorine pools feel the same at a given temperature. Your ideal pool temperature should be set by who’s swimming and what they’re doing, not by the sanitizer type.

How long does it take to raise my pool a few degrees?

It depends on pool size, heater type, weather, and whether you use a cover. Gas heaters warm water faster than heat pumps, while heat pumps perform best in warm, humid air. Using a solar or thermal cover speeds things up by cutting heat loss between heating cycles.

What temperatures are too cold or too hot for safe swimming?

Most casual swimmers find water below the mid-70s uncomfortably cold, and prolonged exposure to very cold water can be risky. At the high end, keep pools under 95°F; very warm water can lead to overheating, especially during vigorous activity or for sensitive swimmers.
