Ocean waves come in many shapes and sizes, but one particular formation called

“square waves” can be a warning sign for swimmers and surfers alike.

Experts advise that if you notice square-shaped waves forming in the ocean,

it’s important to exit the water promptly to ensure your safety.

Square waves, also known as cross seas, occur when two different wave systems intersect at nearly right angles,

creating a distinctive grid-like pattern on the water’s surface.

This phenomenon can make the ocean unusually unpredictable and dangerous.

“These intersecting waves create complex water movements that can easily knock swimmers off balance or overwhelm boats,”

explains marine safety specialist Dr. Karen Mitchell. “

The irregular wave patterns increase the risk of strong currents and underwater turbulence.”

Square waves often develop during periods of changing weather conditions or when waves generated by different storms converge.

While they may look intriguing, these formations are a clear signal to be cautious.

Lifeguards and safety officials recommend that beachgoers pay close attention to wave patterns before entering the water.

If you spot square waves, it’s best to leave the ocean and wait for calmer conditions.

In addition to square waves, other signs of hazardous ocean conditions include rip currents, sudden changes in water color,

and strong undertows. Always check local beach advisories and follow instructions from lifeguards.

By understanding and recognizing these natural warnings,

swimmers and surfers can reduce the risk of accidents and enjoy the ocean safely.
