When you see these square waves in the beach, run away immediately!

The ocean is one of the most mysterious creations that exists in this world. Although it makes up 70% of the whole Earth, there is only a little data known about the creatures that exists in the ocean as well as the various phenomena that happens within its surface.

Just like this particular seemingly ‘square’ shapes formed by the ocean surrounding the area of Isle of Rhe which is located on the west coast of France near La Rochelle in the Atlantic Ocean. Isle of Rhe in France is one such destination which is known for being romantic, as well as bizarre. A tiny island measuring just 19 miles long and three miles wide.

This island has fabulous beaches and great weather that lure tourists not just from Europe but from the rest of the world. But, there is something truly unique about the waves that can be seen from many of its beaches.

To the naked eye, the waves appear to be square shaped, repeating over and over again to form a chessboard pattern on the surface of the ocean. The sight is so unusual that each year, residents and tourists alike, often flock to an old lighthouse on the shore to get a better view from its higher elevation.

This seemingly bizarre phenomenon is finally explained through science.

Isle of Rhe lies at the intersection of two seas, often referred to as a cross sea. Miles under the surface of the ocean where the two meet, two different weather patterns can produce two wave systems traveling at opposing angles.

When these weather patterns last for longer periods of time, they produce these unusually large, square shapes that make for quite a sight!

While they might look beautiful, they also make the waters very dangerous. The strong currents formed due to a cross sea can be much stronger than any riptide we are familiar with. In fact, they can even cause accidents in the ocean.

So, better be careful in case you come across this kind of water disturbance.
