Planning a Beach Vacation? Be Aware of Hidden Dangers

Beach vacations are wonderful—the sun, the sand, and the beautiful rolling waves. Many people that plan a vacation to the ocean have rarely (if ever) swam in one. They head to the beaches filled with tourists and assume that these are safe places to swim. Or maybe they find a beautiful secluded beach and jump into the inviting waters.

But there are oftentimes dangers that they may not be aware of—or any warning signs.

Suggestions on How to have a Safe and Enjoyable Time:

  • Do some research in advance to find out what the water and coastline conditions are.
  • If you are planning on enjoying some water activities, find out if the conditions are conducive to those types of activities. Are the shores rocky or sandy? Are there strong currents, or is it relatively calm? Are the waters known for having dangerous rip currents?

  • Will the beaches be crowded or secluded?

  • Are there lifeguards on the beach? What are the estimated times of high tide and low tide?
  • Use the buddy system when swimming.  If you are unfamiliar with the water, it is best to find a beach with lifeguards.
  • Conditions of the currents and waves can change quickly in the ocean or large lakes like the Great Lakes. Be cautious when swimming during high tide and low tide, especially if you are unfamiliar with the ocean.  To give you an idea, several of us were sitting on a beach (quite a distance from the water’s edge), when suddenly we were surrounded by waves. Everyone on the beach was scrambling to grab their personal belongings…that were now sweeping out to sea with the tide. There was no warning—one minute the waves were along the shoreline, and the next they were engulfing the beach.
  • Look for posted warning signs on the beach or beach warning flags.

Beach Warning Flags:

Typical colors are red, yellow, green, blue or dark purple–adopted by coastal communities worldwide.

  • DOUBLE RED FLAG: Water Closed to Public
    Conditions are too dangerous for even the strongest swimmer. Red flags signify a strong undertow or rough surf.
  • ONE RED FLAG: High Hazard – No Swimming
    The surf is high or there are dangerous currents.
  • RED FLAG with line through SWIMMER: Swimming is Prohibited
  • YELLOW FLAG: Caution – Medium Hazard
    Ocean conditions may be rough and there is the potential for high surf, dangerous undertows, rocks, a sudden drop off, or a high population of bait fish that may attract predators. Children or swimmers that are not as strong should use a lifejacket, in case they get caught in the current.
  • GREEN FLAG: Low Hazard
    It is safe to swim, but still use caution.
  • DARK BLUE or PURPLE FLAG: Dangerous Marine Life
    (usually flown with a Red or Yellow Flag)
    Indicates that sharks, jellyfish, or other dangerous marine life have been spotted in the area.

BEWARE OF RIP CURRENTS – the #1 Beach Danger

Rip currents (sometimes erroneously referred to as riptides or undertows) are the cause of about 80% of most ocean and large lake drownings. They 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.

Rip currents have been known to pull people in while standing in shallow water that is only knee-deep.

Swimmers oftentimes run into a problem when they panic and become exhausted while trying to swim against a rip current.

Watch your children when they are playing in the water–even when right along shore.
Rip currents present a very real danger.   Children have been pulled out to sea, even when playing in shallow water.

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.


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.
