Pool Water Temperature

Perfect Swimming Pool Water Temperature

Everyone has their perfect swimming pool water temperature. You may like it polar bear water cold, or you may prefer it just a degree or two shy of your hot tub. While your ideal temperature is one that is the most comfortable for you, there are a few things we want you to know when it comes to the perfect swimming pool water temperature; and for your hot tub.

There are several factors you need to consider when warming your water to the perfect levels. Take the time to examine all of these factors when you decide on the perfect temperature to create a fun and relaxing environment for you, your family and guests all year long.

No matter which you choose, colder or hotter, you may wonder if there’s anything wrong with swimming in temperatures that your friends may think is a bit unusual. Typically, you probably think that your comfort zone is the only factor in choosing the perfect water temperature, but water temperature has a direct result on ones’ physiology, especially when the temperatures is out of the norm.

It’s interesting to note that for Olympic water sports there are required temperatures. For instance, diving events require water temperature at 79 degrees, while synchronized swimming is between 80-82, and racing events 77-82 degrees. However, these tend to be on the lower end of the spectrum because, as you may guess, slightly cooler temperatures are advantageous due to the highly competitive nature of these events.

If you’re looking for a perfect pool temperature, not too hot and not too cold, is just right. For casual swimming, we recommend you keep your in-ground swimming pool between 82-85 degrees Fahrenheit.

If you’ve joined the ranks of people that have added a hot tub to their swimming pools, you are already aware that the temperature of the hot tub is warmer than your pool water. How much hotter should it be to feel comfortable?

All new hot tubs come with a maximum temperature limit of 104 degrees Fahrenheit. Many new owners ask if it is possible to raise the temperature beyond that limit. If you have a new tub, the answer is no. For your spa, we recommend that you set it at 102 degrees.

When you get your new hot tub, try adjusting the water temperature to around 98° F before you get into the water for the first time. If that temperature seems too cold, slowly increase the temperature until you reach a level that is right for you.

Even with the limit on hot tubs and spas, you should still also keep a separate water thermometer in the hot tub to check the temperature before you enter the water.

Of course, there are economic reasons to keeping the water temperature of your pool optimal. The energy consumption for each degree rise in temperature will cost 10%–30% more in energy costs.

Also, we recommend that you turn the temperature down or turn off the heater whenever the pool or hot tub won’t be used for several days. It’s a myth that it takes more energy to heat your pool back up to the desired temperature than you save by lowering it or turning off the heater.

When you have your pool and hot tub at an optimal temperature, we are confident you’ll enjoy them both all summer long.
