A riptide is a strong, narrow current of water flowing away from the shore. It's formed when waves break near the coastline and the water needs to find a way back out to sea. Imagine it like a watery conveyor belt pulling you away from the beach. Riptides are dangerous because they can quickly carry swimmers far from shore. Unlike a whirlpool, which spins, a riptide is more like a river flowing against the waves. If caught, don't panic; swim parallel to the shore!
