What Are Rip Currents?
Rip currents are powerful, narrow channels of fast-moving water that flow from the shore out to sea. Though they can occur anywhere, certain beaches are more prone to them due to topography and the shape of the ocean floor. Piers, jetties, and other infrastructure that extend from the beach into the water can also increase the chances of a rip current. Recognizing the warning signs of rip currents is crucial for staying safe at the beach.
Warning Signs of Rip Currents
Differences in Water Color: rip currents often appear darker than the surrounding water because they are deeper. The water may also look murkier or have more sediment, which can give it a different color.
Choppy Water: water within the rip current channel can appear choppier and more turbulent than the surrounding waves.
Breaks in Wave Patterns: look for a gap in the wave pattern where the waves seem to be lower and breaking less. This is often where the rip current is moving out to sea.
Foam and Debris: rip currents can carry foam, seaweed, and debris from the shore out into deeper water. If you see a stream of debris moving steadily seaward, it could indicate a rip current.
Ripples on the Surface: a noticeable difference in the water's surface texture, such as a smooth area surrounded by breaking waves, can indicate a rip current.
Safety Tips and Prevention
Swim Near Lifeguards: always swim in areas monitored by lifeguards. They can provide warnings and assistance if needed.
Observe Warning Signs: pay attention to posted warning signs or RED flags that indicate hazardous water conditions, including rip currents.
Ask!: if you’re unsure, ask lifeguards or local authorities about the presence of rip currents before entering the water.
Understand Beach Conditions: learn about the typical beach conditions in the area you visit. Some beaches are more prone to rip currents than others.
What to Do If You’re Caught in a Rip Current
Stay Calm: panic can lead to exhaustion. Keep calm to conserve energy.
Don’t Fight the Current: swim parallel to the shore to escape the narrow current channel. Once out of the current, swim back to shore at an angle.
Float and Signal for Help: if you can’t escape, float or tread water and wave your arms to signal for help.

Understanding how to identify rip currents and knowing how to respond if caught in one can save lives. Prioritize safety and stay informed about the beach conditions.
Facts from the United States Lifesaving Association - Rip Current Safety
- Rip currents do not pull people under the water—they pull people away from shore.
- Rip current speeds vary. Average speeds are 1-2 feet per second, but they have been measured as fast as 8 feet per second—faster than an Olympic swimmer!
- Rip currents can be very narrow or more than 50 yards wide.
- Sometimes, a rip current ends just beyond the line of breaking waves; however, others may continue to flow hundreds of yards offshore.
