Picture this: you’re lying on a sun-kissed beach, the warm sand cradling your body, and the rhythmic sound of waves gently lapping against the shore. It’s the epitome of relaxation, the kind of holiday scene we all dream of. But while the ocean offers beauty and tranquility, it also harbors hidden dangers that most people aren’t aware of. One such danger is the phenomenon of square waves, a rare yet potentially deadly occurrence that every beachgoer should be aware of.

Square waves, also known as a “cross sea,” are a unique and visually striking ocean phenomenon where waves intersect at right angles, creating a pattern that resembles a checkerboard. While this sight might seem mesmerizing from a distance, it’s actually one of the most dangerous conditions you can encounter in the ocean.

Square waves form when two distinct wave systems collide in the ocean. This typically happens when a windsea, generated by local winds, meets a swell, which is a longer wave created by distant weather systems. The result is a grid-like pattern of waves that can be incredibly treacherous for both swimmers and boats.

The danger of square waves lies in their unpredictable nature. Unlike regular waves, which move in a single direction, square waves push water in multiple directions simultaneously. This can create powerful currents that are difficult to escape, even for strong swimmers. Boats and ships can also struggle to navigate through these conditions, as the intersecting waves can cause them to capsize or lose control.

In fact, the European Space Agency noted in 2010 that square waves are more common than most people realize and have been linked to a significant number of ship accidents. A 2004 study found that a large percentage of ship accidents occurred in crossing sea states, highlighting the severe risks posed by this phenomenon.

If you’re curious to see square waves in person, one of the best places to observe them is along the western coast of France, on the Île de Ré. From a safe distance, these waves create a stunning visual display. However, it’s crucial to admire them from land, as venturing into the water during a cross sea is extremely dangerous.
