Rip currents are powerful, narrow channels of water that flow away from the shore. They can form when waves break over sandbars or other underwater features, creating a strong current that can pull swimmers out to deeper water. Understanding how to identify and avoid rip currents is crucial for beachgoers to ensure their safety. If caught in a rip current, it is important to stay calm and conserve energy. Swim parallel to the shore until you are out of the current, then swim back to the beach at an angle. Always check local beach conditions and heed any warnings about rip currents before entering the water.
