Swim north or south out of Rip, not against
sandbar the volume in the trough (water trapped between the beach and sandbar) increases and the additional volume of water causes an increasingly greater volume to flow through the path.
As water flows along the path, it will move sand and create a deep underwater channel from the shoreline through the sandbar.
As waves break near the beach, they cause a change in bathometry (the contour of the ocean bottom), which causes a constant change in the sandbar and thus rip current locations and severity are constantly changing.
Rips can open at any given time, sometimes referred to as “flash rips.”
Just last week I was out swimming, and I could see little rips opening up where just minutes before there weren’t any in the area where I was swimming. It was a rough, choppy day and the sandbar was being broken away.
Another factor that has an influence on the frequency and severity of rip current activity is water depth, which is directly related to changing tides. Therefore, rip current risk may be reported as moderate at 1 pm and become high at 4 pm. The Ocean City Beach Patrol provides rip current assessments to NOAA 3 times each day. We have also worked directly with scientists to understand rip currents and how to better forecast and predict them.
Although rip currents do not pull a person under water as a lot of people believe, it is the deep channel cut into the sandbar that gives the impression that a swimmer may be pulled down.
What is happening is a non-swimmer who intended to remain only in waste deep water is moved by the rip current into an increasingly deeper water channel.
Since they cannot swim, they try to stand on the bottom or bounce to keep their head above water, and as they move away from the shore, the water becomes over their head and they are no longer able to keep it above water.
Therefore, a person watching from the beach may think that what they believe they are seeing is a person being pulled under. In fact, it is a non-swimmer who does not have the ability to keep their head above water.
If this occurs while the Beach Patrol is on duty, the lifeguard will simply assist the person back to safety. However, if this occurs while lifeguards are not on duty, the outcome could be deadly (over 98 percent of all drowning deaths in Ocean City over the past 90 years have occurred when the Beach Patrol was NOT on duty).
You may believe that only non- swimmers drown because of rip currents while many rip current drowning victims had moderate to good swimming ability.
This brings up the question, why would a person who knows how to swim, drown? The answer is simple: Panic, fatigue, and lack of ocean awareness all contribute to the outcome.
A rip current is very much like a treadmill. As water is flowing away from the beach, a swimmer attempting to swim straight in will make little or no progress against the outgoing current.
Since a rip current may flow faster than an Olympic swimmer (like Michael Phelps) can swim, swimming against this current only causes a person in this situation to become fatigued while getting no closer to the beach. Eventually they become so fatigued that they are no longer able to keep their head above water and once they slip below the water’s surface and are no longer able to get air, they become unconscious and only have moments before they become a statistic.
In contrast, a swimmer or someone with a flotation device can easily escape the pull of the rip. By nature, a typical rip current is not very wide, usually 20 yards at most, which means that a person who is pulled out can be out of the rip after a few swimming strokes.
Also, once the rip current flows through the cut in the sandbar the pull disperses and the current no longer continues to pull you away from shore.
With these facts in mind if you find yourself being pulled away from shore, do not panic. Simply swim parallel to shore and once you no longer feel the pull of the rip, swim back into shore.
To help escape the “grip” of the rip, swim with the littoral current (north or south). Before you go swimming, take time to study the water and know which direction you would want to swim out of the rip. If you feel you are unable to swim across the rip, relax, let it take you out to the sandbar, and then swim back to shore.
Whatever you do, never abandon a flotation device, and always signal the lifeguard if you want their assistance. In most cases they will already be on their way to assist you back to safety.
Even our lifeguards will not attempt to swim straight in against a rip current. They use their knowledge of the ocean to swim parallel to the beach until they are out of the rip current and then make their way back into safety with a victim in tow holding onto the buoy that the SRT has handed them as a flotation device to keep them above water.
If you can remember the word rip then you can remember what to do to save your life, R = Relax and do not panic, I = I need help (wave your arm), P= swim Parallel to return to safety.
For more information about rip currents and other water safety topics visit ococean.com/ocbp and follow the safety button. The National Oceanic and Atmospheric Administration, or NOAA, has a very informative site to learn more about how they occur and how to remain safe, at ripcurrents.noaa.gov/ .
Not only do our SRTs play an important role in educating the public about rip currents and beach safety, as an organization, we have been involved in scientific research about rip currents and surf zone hazards with NOAA, the University of Delaware, Johns Hopkins University, and Maryland Sea Grant. We were also recognized internationally for educational outreach efforts.
It’s always exciting to be able to network with other organizations, in- cluding NOAA, about current rip current and surf zone research. The administration also presented the Beach Patrol with an award for “Rip Current Awareness and Prevention” at a City Council meeting a couple of seasons ago.
Scott Schumann, an IT officer from NOAA, comes each year to train our lifeguards as we continue our partnership for identifying, predicting and understanding rip currents.
My best advice to you is to only swim when lifeguards are on duty, and you can always approach any of our friendly and knowledgeable lifeguards and ask them to talk to you about current conditions and information about rip currents, as well as looking at the rip current diagram on the back of every stand along the beach.
