Why Cool Your Spa in Summer?

A spa pool doesn’t just have to be for winter. Many spa owners enjoy cooling their spas during the summer months to create a more refreshing experience. Lowering the water temperature can help you beat the heat while still enjoying the benefits of hydrotherapy, relaxation, and quality time with family and friends. Plus, cooling your spa can reduce your energy consumption during the warmer months, as the heater won’t need to work as hard.

How to Cool Your Spa Pool in Summer: 6 Effective Tips

1. Adjust the spa temperature

The first thing you’ll want to do is adjust the temperature on your spa’s control panel. See the manual for your spa model for specific instructions. Most modern spa controllers allow you to easily reduce the water temperature by pressing the down arrow on the touchpad.

Make sure to give the water some time to adjust, as cooling it down might take a full day in hot weather. During extremely high temperatures, your spa may struggle to cool, so follow the additional steps below.

2. Add cold water to your spa to cool it down

If you’re in need of a quick fix, you can manually add cold water to your spa to lower the temperature. Simply drain some of the warm water and replace it with cold water from your hose. This is especially helpful if your spa has been in direct sunlight and has heated up more than expected.

Tip: Use this method sparingly to avoid affecting the chemical balance of your spa water. After adding fresh water, you’ll need to check and adjust the water balance to maintain ideal pH and alkalinity levels.

3. Add ice to cool down your spa or hot tub

If you prefer a more fun approach, add ice! You can either add ice directly or freeze containers like milk cartons filled with water. These giant ice packs will lower the temperature without affecting the water balance as much as ice cubes might.

4. Shade your spa for natural cooling and sun protection

Shading your spa is an excellent long-term solution for keeping the water cool. An umbrella with an adjustable canopy is a great option, as you can re-position it to block sunlight throughout the day.

Additionally, placing your spa near natural shade, such as a tree, can make a difference.

Be aware however, if you place it under trees you’re likely to have issues with leaves falling into the spa water which can cause issues with filters and water quality. That’s why at Spa World, we always recommend shading your spa with either an umbrella or pergola.

Consider using pergolas for more permanent shading solutions. They add a stylish touch to your outdoor space while protecting your spa from the sun. Check out pergolas at Spa World to provide lasting shade for your spa.

Umbrellas are also a great option, especially if you want to move it around with the sun. Explore Spa World's range of outdoor umbrellas to keep your spa shaded and cool during summer.

5. Remove the spa cover for a colder spa pool

Removing your spa cover can help release trapped heat and allow the water to cool faster.

However, keep in mind that the cover also protects your spa from debris, UV rays, and water contamination. Make sure your spa is fenced for safety if you opt to remove the cover.

6. Use a heat pump to cool the spa water

Just like reverse-cycle air conditioners, heat pumps can operate in reverse to cool your spa water. They extract heat from the water and release it into the surrounding air, offering one of the most energy-efficient methods to regulate temperature.

This is particularly useful during hot weather when maintaining a comfortable spa temperature can be challenging.

With a heat pump, you can cool your spa water to as low as 5°C, effectively transforming your spa into a cold plunge pool or ice bath.

All Vortex and Fisher™ spa pools are heat pump compatible, giving you the flexibility to enjoy cool water in summer or warm relaxation in winter.
