Swimming at water parks cools the body and reduces the physical effects of extreme heat [1, 2].
This cooling mechanism is critical during heat advisories, as it provides a scalable way for the public to avoid heat-related illness when indoor cooling is unavailable.
Jaden Knowles, a meteorologist with the 9NEWS Weather Impact Team, said that water parks work because water absorbs body heat [1]. Once the water is on the skin, evaporation removes that heat, which creates a cooling effect that helps people manage high temperatures [1].
These facilities have seen increased use during recent weather events. In Ohio, parks such as Cedar Point Shores, Zoombezi Bay, and Soak City at Kings Island served as refuges during a heat advisory on June 29, 2026 [2]. Similar patterns appeared in South Mississippi at Serengeti Springs, and at various spray parks in Sacramento County [3, 4].
Public spray parks offer accessible cooling for all ages. In North Natomas Regional Park, two-year-old [1] Parker Beverly used the park's misting features to cool off alongside her dog, River [4].
While traditional pools provide immersion, the combination of moving water and air flow in water park attractions enhances the evaporative process. This makes these environments more effective at lowering core body temperatures than standing water alone [1].
“Water absorbs body heat and evaporation removes that heat.”
The reliance on water parks and spray parks during heat waves highlights a growing need for public cooling infrastructure. As extreme temperature events become more frequent, the physics of evaporative cooling provides a low-energy alternative to air conditioning for immediate heat relief.
