Quick Answer
Beachgoers should be aware of the appearance of discolored water, lack of breaking waves, and foam lines as indicators of a rip current, and know how to quickly escape by swimming parallel to the shore.
Identifying Rip Currents
Rip currents can be identified by a lack of breaking waves, discolored or murky water, and foamy lines or channels pulling water away from the shore. These channels can be narrow or wide, and can move quickly, often at speeds of up to 8 feet per second. Beachgoers should be aware of these indicators and take action if they notice a rip current.
Escaping Rip Currents
If caught in a rip current, the most effective way to escape is to swim parallel to the shore, rather than trying to swim against the current. This can help you avoid exhaustion and stay close to shore. Aim to swim 90-100 degrees away from the current, and continue until you are out of the channel. Do not try to swim directly back to shore, as this can cause you to become more exhausted.
Flag Indicators
Many beaches use warning flags to indicate the presence of rip currents. A red flag indicates high hazard conditions, including strong currents and large waves. A double red flag indicates a closed beach, and a yellow flag indicates moderate hazard conditions. Beachgoers should always check the flags before entering the water, and be aware of the local warning system.
