This phenomenon is a rare but dangerous occurrence, where waves create a unique pattern resembling square waves on the water’s surface.
Definition of “Square Wave”
Typically, waves approach and depart from the coastline parallel to the shoreline.
However, in certain regions around the world, waves form a pattern that resembles a table on the water surface.
This phenomenon, known as “square waves,” is exceedingly rare but poses a significant danger. When observed from above, it appears as though a wire mesh beneath the water transforms into square waves.
The aesthetic beauty of “square waves” belies their inherent dangers, having even been the cause of accidents, such as boat capsizing, as reported by Surfer Today.
Causes of “Square Waves”
“Square waves” occur when two wave systems moving in opposing directions meet and intersect at right angles.
These wave systems often originate from two superimposed weather systems, such as when a high-pressure system carrying cool air collides with a low-pressure system containing warm air, according to The Rain Forest Site.
Despite the weather systems being usually distant from each other, the resulting waves can travel hundreds of miles. Once they meet, they clash and create waves that exceed a 45-degree angle.

The Danger of “Square Waves”
At first glance, the waves may appear serene, but in reality, this phenomenon often carries strong whirlpools, making escape difficult.
Being caught in this wave becomes challenging to overcome, as one has to contend with the simultaneous forces of two different wave systems.
In light of this, it is advised to retreat back to the shore promptly upon encountering the “square wave” on the beach.
Furthermore, “square waves” have been linked to boat accidents and drownings. The European Maritime Safety Agency has reported instances of these accidents occurring due to wave collisions outside the shore.
“Square waves” are an incredibly rare occurrence that can manifest and disappear within minutes on various beaches worldwide.
The formation of “square waves” can also extend beyond the coastline and is particularly likely to occur in coastal areas, as stated by The Sun.
However, the predictability of this wave type is low, especially when there are multiple simultaneous sounds, shallow wave angles, or strong winds.
Ile de Ré – Ré Island – in France is the most renowned location for observing “square waves.” Despite the wave phenomenon only occurring at specific times of the year, this island off the coast of La Rochelle remains a popular tourist destination, according to The Sun.
