If your destiny is a beach vacation this year, it’s important to know how to spot threatening water conditions and how to avoid/or escape them–which could save your life.
Be Aware of the #1 Beach Danger — Rip Currents:
I discussed rip currents in a previous post, but with summer coming upon us, it bears repeating. Rip currents (sometimes erroneously referred to as riptides or undertows) are the cause of about 80% of most ocean and large lake drownings. These are strong, narrow channels of water that can pull swimmers away from shore rapidly, no matter how strong a swimmer they are. They do not pull swimmers under the water, but rather out to sea.
Rip currents have been known to pull people in while wading in shallow water that is only knee-deep. Rip currents present a very real danger–children have been pulled out to sea, even while playing along shore.
Where swimmers run into a problem is when they panic and become exhausted while trying to swim against a rip current rather than out of it.
Rip currents can be found on some of the most popular beaches–and many travelers are unaware of their dangers. This topic is important to me, because I saw firsthand what can happen if caught in a rip current. While on a business trip to a popular resort, there were two people in our group that narrowly escaped drowning in a rip current. That same week, a child was suddenly pulled out to sea while playing in the sand in the shallow water (thankfully they had a life jacket on and were rescued). There were no warning signs or beach flags. I later found out that this beach has dangerous waters…but the majority of beachgoers (me included) had no idea.

How to Spot Rip Currents:
It may be difficult to identify the signs that a rip current is present, because they can be very subtle. Before entering the water, look for the following clues. You may see one, all of them, or possibly even none of them (even though a rip current may be present). Remember…a rip current can be right along shore and can pull you out when you are just wading.
- A channel of churning, choppy water.
- A line of seaweed, a “river” of foam, or debris that is moving steadily out away from the shore, as opposed to outside the rip where debris or foam is floating toward the shore.
- A notable difference in water color—it may be more opaque, cloudier, or muddier than the surrounding water or it may appear as darker or lighter than the water around it, depending on the angle of the sun.
- A break in the incoming wave pattern as they roll into shore. It may be an area where the waves are not breaking as quickly or as violently. The water may look flat where the rip is, in contrast to the lines breaking waves on either side.
- Rip currents can be prevalent around jetties, breaks in sandbars, piers, and groins (a long, narrow structure built out into the water perpendicular from a beach to prevent beach erosion).

What Should You do if You Get Caught in a Rip Current?
You will know it when it happens. Suddenly you will feel a strong pull of water lifting you up and moving you rapidly out to sea. If you are aware of what is going on, you can calm yourself down by reminding yourself that you can swim out of a rip current—you just need to know how to do it. Remember that the rip current will generally dissipate outside the breaking surf, and it is a narrow channel of water.
How to Safely Swim Out of a Rip Current:
1. Most importantly, don’t fight the current or try to swim back to shore. This will cause you to become exhausted, and you won’t make any headway. A rip current can flow seaward at 5 to 8 mph.
2. Swim parallel to the beach (which is perpendicular to the rip current).
3. Once out of the current (it will end!), swim at an angle (away from the current) toward shore. Rip currents are concentrated in one area, so you can swim out of them by going parallel to shore.
4. Sometimes the rip current is diagonal to shore; if you try to swim parallel to shore but aren’t making any progress, turn around and swim parallel to the shore in the other direction.
5. If you cannot swim out of the current, float or tread lightly until you are out of the current (they usually dissipate outside the breaking surf), and then swim back to shore at an angle away from the rip current. If treading water, face shore, wave your arms, and yell for help.

6. Unless you are trained in swim rescues, do not try to swim out to rescue someone. Many drownings occur through these attempts. Instead, throw a floating device (even a cooler or ball) or toss out a rope. Shout directions to them loudly—urging them to swim parallel to shore—and try to keep them calm, while calling for help.
Keep in mind that most people drown because they panic and try to swim straight back to shore against the rip current.

If you are not familiar with the water conditions, swim at beaches with a lifeguard.
