Most experts agree that the ideal temperature for a Vancouver swimming pool is between 25 – 28°C. There are, however, some important factors to consider when picking the right temperature for your own pool. It goes beyond personal preference – you should also consider who is using the pool, and energy and maintenance costs.

Why is finding the ideal temperature important?

Finding the ideal temperature for your Vancouver swimming pool will mean the pool gets used more often, will not cost an arm and a leg to heat and will not cause maintenance issues. 

Who is using the pool?

It is important to consider who is using the pool when you are deciding the correct temperature.

There are three groups that may need a special pool temperature:

Kids & Seniors

Children and seniors have a harder time regulating their body temperature, so they require the pool temperature slightly higher for comfort. This is especially true for anyone with arthritis – a colder pool can exacerbate joint pain.

Pool temperatures from 29°C and 31°C may be best for this age group, if they are using your pool often.


If your pool is an extension of your home gym, you may find a cooler temperature more conducive to your exercises, though it depends on the type of exercise. Here are some pool temperature considerations:

Below 28°C
It might feel a bit brisk when you first get in, but if you are doing vigorous activity, such as lap swimming, you may appreciate the cooler temperature.

28 – 31°C
This is the ideal temperature range for moderate exercise, like aqua aerobics. This temperature is comfortable to ease into, but not so hot that it could affect your heart.

31 – 33°C
This is the upper range for moderately active water exercise and is more appropriate for lower-intensity workouts. Anything exercise too vigorous at this temperature could affect your heart.

The cost of having a pool at a suboptimal temperature

There are energy and maintenance cost considerations for picking the ideal temperature for your Vancouver swimming pool.

Energy cost

One of the biggest costs to a pool owner is the cost of heating your pool. If you are constantly adjusting your temperature, you will find the energy needed to get your pool to the ever-changing temperature is going to increase, thereby increasing your energy bills. 

If someone in your household is older, if anyone is living with arthritis, or you have senior guests, you may want to consider getting an inground hot tub instead of raising and lowering your pool temperature often.

Maintenance costs

Constantly adjusting the temperature of your pool will also put a strain on your pool heater, leading to potential malfunctions and possible early retirement – which means you will have to replace your pool heater sooner than if you were keeping the pool at a constant temperature.

High pool temperatures can also wreak havoc on your water chemistry. Bacteria and algae will begin to thrive at around 29°C. If you keep your pool temperature lower than this, it will not get rid of algae and bacteria, it will just make it more difficult to grow rapidly and become a problem. The higher the temperature, the more often you will have to treat your pool with chemicals, increasing the maintenance costs.

Not only that, it can also put a strain on your pool heater to be constantly adjusting the temperature. It will also wreak havoc with your water chemistry.

The ideal temperature for your Vancouver swimming pool is ultimately a personal preference. Just be sure to consider the other people using your pool, the wear and tear on the pool heating components and the cost of adjusting the temperature.
