A hot tub is designed to be relaxing year round, but when temperatures climb into the 90s, it can feel like the last thing you want to sit in. The good news is that a few adjustments make your spa just as enjoyable in the middle of summer as it is in December.
Lower the Temperature for Summer Use
Most owners keep their spa around 100 to 102 degrees in the winter, but dropping it a few degrees in the summer, closer to 96 to 98 degrees, can make a big difference without sacrificing the relaxation benefits.
Use It in the Evening
Once the sun goes down, outdoor temperatures drop and a hot tub feels far more comfortable. Evening soaks also tend to help with winding down before bed, which is an added benefit during long summer days.
Keep the Jets Off for Pure Soaking
Running jets adds friction, which can raise water temperature slightly. If you are using your spa mainly to relax rather than for hydrotherapy, turning off the jets for part of your session can help keep things comfortable.
Stay on Top of Water Care
Heat speeds up chemical breakdown and evaporation. Check your water levels weekly, and keep an eye on sanitizer levels since summer heat can cause them to deplete faster than in cooler months.
Quick Reference
| Adjustment | Why It Helps |
|---|---|
| Lower temp by 4 to 6 degrees | Keeps soaking comfortable in the heat |
| Soak in the evening | Cooler air temperature balances water temperature |
| Reduce jet use | Less friction means less added heat |
| Check water weekly | Prevents evaporation and chemical imbalance |
FAQ
Will lowering the temperature damage my hot tub? No. Adjusting the set temperature seasonally is a normal part of hot tub ownership and will not affect the equipment.
Is it safe to use a hot tub in the summer at all? Yes, as long as you stay hydrated and avoid long sessions during the hottest part of the day.
Should I cover my spa during the day to keep it cooler? Yes. Keeping the cover on when the spa is not in use helps regulate temperature and reduces evaporation.
