Quick Answer
Signs of dangerous rip currents include discolored or foamy water, lack of breaking waves, or a channel of churning water that pulls away from the shore. Watch for a distinct boundary between the calm and turbulent water.
Identifying Rip Currents
When identifying rip currents, look for a channel of fast-moving, churning water that pulls away from the shore. This can be discolored or have a distinct boundary. Avoid swimming in areas with a lack of breaking waves, as this can indicate a strong current. Keep an eye out for signs of erosion or changes in the shoreline.
Escape Techniques
To escape a rip current, do not try to swim against the current. This will only exhaust you. Instead, swim parallel to the shore at a 90-degree angle to the current. This will allow you to move out of the current’s path. Aim for a buoy or a lifeguard if possible. If you are unable to swim parallel, float on your back and wait for help.
Flags and Warnings
Rip currents are often indicated by warning flags at the beach. In the United States, a red flag usually indicates strong currents or other hazards. A yellow flag may signal moderate conditions, while a green flag indicates calm waters. Pay attention to the flags and warning signs, and always check with lifeguards before entering the water.
