4 Things to Know About Setting Your Pool Temperature

78–82°F is the sweet spot for most adults This range keeps the water comfortable for swimming without feeling cold or soupy. Below 75°F feels cold unless you’re doing laps, and above 85°F gets sticky.

Adjust based on who’s swimming Kids and older adults prefer 84–86°F. Lap swimmers like it cooler, around 78–80°F. If everyone uses the pool, split the difference at 80–81°F.

Every degree above 78°F costs money Heating costs add up quickly, especially with a gas heater. Pick a temperature that’s warm enough to enjoy but not so warm you’re paying for a hot tub you rarely use.

80°F is the default for regular swimmers It’s not a massive compromise—it’s the temperature people who actually swim choose.
