Rip Current Safety: What is a Rip Current?

Rip currents are narrow channels of water moving from the beach to the ocean. They can be hard to detect and vary in width and strength. Rip currents form due to waves and sandbars, and are common on ocean beaches and large lakes. They pose a danger to swimmers, as they can pull them out to deeper water. Most lifeguard rescues are due to rip currents. They form when waves break on sandbars, creating channels for water to flow back to the sea. Obstacles like piers and jetties can also influence their formation. Rip currents can occur suddenly and in different beach areas.
