5 Things to Know About Swim Spa Temperature in Cool Weather

Keep the water between 88 and 90°F This range is warm enough to prevent tensing up when you first get in, but cool enough to avoid overheating during a swim.

Drop to 85–87°F for high-intensity swimming If you are doing laps or resistance swimming, a lower temperature keeps your core from overheating.

88–90°F is ideal for floating or lounging in cold air For light paddling or just relaxing, this range keeps you comfortable without getting too hot.

Most swim spas default to around 85°F That setting works in summer, but on a 50°F day, you will shiver the moment you step out.

Bump up the temperature a few degrees for cooler weather Your muscles will stay loose, and you will enjoy the spa more in cold conditions.
