The Swimmer's Circle

The Swimmer's Circle refers to the pattern of water movement that forms around a swimmer, especially in a pool. When a person swims, they create currents and turbulence that cause water to flow toward the edges of the pool, then circulate back toward the center along the sides. This movement can lead to uneven water temperature and clarity, often making the area near the walls appear cleaner or more disturbed. Understanding this pattern helps pool designers and maintenance staff optimize circulation systems for better water quality, ensuring an even distribution of chemicals and temperature throughout the pool.
