What is a seawhirl?

A seawhirl is a powerful oceanic phenomenon characterized by a rotating column of water, often resembling a whirlpool. It typically forms in areas where strong currents, tides, or underwater topography interact, causing water to swirl in a circular motion. Seawhirls can vary in size and intensity, and while they are generally not dangerous, they can pose risks to small boats and swimmers. Understanding seawhirl behavior is important for navigation and marine safety.
