Spülströme

Spülströme, also known as rip currents, are powerful, narrow currents that flow away from the shore, typically within a few meters of the beach. They are caused by waves breaking near the shore, which creates a longshore current that moves parallel to the beach. This current then flows back offshore, creating a narrow, fast-moving current that can pull swimmers away from the shore. Rip currents are most common in areas with sandy beaches and strong waves, such as coastal regions with large surf zones.

Rip currents can be dangerous for swimmers, as they can drag them away from the shore and into deeper water, where they may struggle to swim back to safety. The speed of a rip current can exceed 2 knots (3.7 km/h), making it difficult for swimmers to swim against it. To stay safe, swimmers should always swim parallel to the shore and avoid swimming in areas with strong waves or near piers and jetties, which can create rip currents.

Lifeguards and beach safety officials monitor rip currents and provide warnings to swimmers. They use flags, buoys, and other visual aids to indicate the presence of rip currents and to guide swimmers back to shore. In some cases, lifeguards may use rescue equipment, such as ropes or tubes, to pull swimmers out of the water. It is important for swimmers to follow the advice of lifeguards and to never attempt to swim against a rip current.
