A trip to the beach is a dream come true for many of us. The sun, the warm sand, and the calming sounds of the ocean create the perfect atmosphere for relaxation. But it’s important to remember that safety should always be our top priority when enjoying the beach and the ocean.

While most of us are familiar with rip currents and changing tides, there’s another potential danger that we may not be aware of – square waves. These unique waves, also known as “cross seas,” occur when two sets of waves intersect, creating a grid-like pattern that resembles a checkerboard. Although square waves are quite rare, they are most commonly found near the coast.

Square waves can be particularly hazardous for both boats and swimmers. They can generate waves as high as 10 feet, making it difficult to navigate and altering wind patterns. While it’s unlikely that you’ll find yourself caught in square waves, it’s crucial to know what to do if you ever encounter them.

If you happen to be in the water and notice larger swells and the challenge of swimming against two distinct currents, you may be facing square waves. In such a situation, it’s best to avoid venturing too far from the shore in the first place. And if the waves become even larger or the conditions worsen, it’s vital to exit the water promptly.

Square waves are more likely to pose a danger to boats and ships that are farther from the shore. So if you’re at the beach during such conditions, it’s safer to stay in the shallower waters. You can either remain on the shore or take a quick dip in the shallow water until the weather and ocean conditions improve.

Remember, safety should always come first when enjoying the beach and the ocean. Make sure to share this important information with your family and friends to help ensure their safety too.
