Square Waves in the Ocean: A Rare and Fascinating Phenomenon

Square waves, also known as cross seas, are a rare and fascinating ocean phenomenon characterized by two wave systems intersecting at right angles, creating a checkerboard pattern on the water's surface. They are not actually square, but rather resemble a series of rectangular waves, giving them their name.

What Causes Square Waves?

Square waves are usually formed when two sets of waves with different origins collide.

  • One set of waves is typically generated by local winds and travels in one direction.
  • The other set of waves may be swell from a distant storm, often traveling in a different direction.

The collision of these two wave systems creates the distinctive squared appearance of the waves.

Where Can Square Waves Be Found?

Square waves are most commonly observed in coastal areas where two wave systems frequently collide. The intersection of the North Atlantic Current and the Gulf Stream is one such location. Other locations include the Strait of Gibraltar, the English Channel, and the coast of France.

Are Square Waves Dangerous?

While visually captivating, square waves can be dangerous for boats and swimmers. The unpredictable nature of their intersection can create strong currents and unpredictable wave heights.

Large waves can overturn smaller boats, and strong currents can pull swimmers out to sea. It is important to exercise caution and avoid swimming or boating in areas where square waves are present.

How to Spot Square Waves

Square waves are not always easy to spot as they are a transient phenomenon. However, if you notice two sets of waves colliding at right angles or see a checkerboard pattern on the water's surface, you may be witnessing square waves.


Square waves are a testament to the power and complexity of the ocean. They are a reminder of the forces that shape our planet and the importance of respecting the power of nature. While visually captivating, these waves can also be dangerous. It is crucial to understand their potential dangers and exercise caution when encountering them.
