Hot tubs aren’t just for winter! When managed properly, they can be a refreshing oasis all summer long. In the peak of Florida’s heat, however, you may find your spa water feeling more like a sauna than a soothing escape. Luckily, with a few simple adjustments, your hot tub can transform into the ultimate cooling retreat.
Here’s your expert guide to lowering your hot tub water temperature for relaxing, invigorating summer soaks.
Why Use Your Hot Tub in Summer?
While many associate hot tubs with cold weather, using your spa during the summer has unique benefits:
- Muscle relaxation after outdoor activity
- Cooling hydrotherapy, when the water is properly adjusted
- A tranquil space for morning meditations or evening wind-downs
The key is finding the right water temperature that keeps you cool and comfortable.
Ideal Summer Hot Tub Temperature
For hot weather use, most spa owners aim for a water temperature between 85°F and 95°F—a significant drop from the standard 100°F–104°F.
- 85°F–90°F: Cool and crisp, perfect for daytime dips
- 90°F–95°F: Refreshing, yet warm enough to soothe muscles
- Below 85°F: More like a plunge pool—great for short, energizing soaks
How to Lower Your Hot Tub’s Water Temperature
Here are several effective strategies to keep your spa water cooler in the summer:
1. Adjust the Temperature Settings
The simplest method: manually lower the set temperature on your spa’s control panel. Most hot tubs allow you to set the temp as low as 80°F.
- Turn it down in the morning so it’s ready by afternoon
- Keep the cover off during the night to encourage heat release
2. Use an Economy or Sleep Mode
If your spa has multiple settings, Eco Mode or Sleep Mode limits heating to specific times, which helps prevent the water from warming up during the day.
- Reduces unnecessary heating cycles
- Helps maintain a stable, lower temperature
3. Circulate Water Without Heating
Running your jets and pumps without the heater on keeps water moving (which prevents stagnation and improves filtration) while also helping it stay cool.
- Schedule short filter cycles during cooler parts of the day
- Turn off the heater completely when not in use
4. Add Cool Water
Partially draining and refilling your hot tub with fresh, cooler water can drop the temperature quickly. This is especially helpful before weekend use or gatherings.
- Drain 6–12 inches and replace with hose water
- Be sure to rebalance your water chemistry afterward
5. Use Spa Chillers or Cooling Systems
Some high-end models (or add-on systems) offer dedicated chillers that can actively cool the water, perfect for tropical climates like Florida’s.
- Great for those who want precise temperature control
- Available for many swim spas and luxury tubs
Pro Maintenance Tip: Keep Water Clean in Summer
Cooler water still needs consistent care. Higher use during warmer months can lead to cloudy or unbalanced water. Be sure to:
- Test and balance pH, alkalinity, and sanitizer levels
- Clean filters more frequently (every 1–2 weeks)
- Shock your water weekly to prevent bacteria buildup
