Everyone loves swimming in the ocean during the summer. It’s a great way to have fun and cool off. But it’s important to always be cautious and aware of our surroundings. One moment of inattention can lead to a dangerous situation. Rip currents and changing tides are already well-known risks, but there’s another danger that you need to be aware of – square waves.

Square waves, also known as cross seas, are a fascinating but hazardous phenomenon. They occur when two or more waves come together, creating a pattern that looks like a checkerboard. These square waves can be deceivingly beautiful, but they can also be very dangerous.

According to the European Space Agency, cross seas are quite common in the ocean, especially when different wave systems exist. In fact, a large percentage of ship accidents happen in crossing sea states. The swells caused by these square waves can reach up to ten feet in height, making it difficult for boats and swimmers to navigate the waters safely.

If you ever come across square waves, it’s important to stay out of the water. Avoid using boats or even swimming in these perilous conditions. Instead, take this opportunity to relax on the beach and wait for the weather to improve. It may be a rare occurrence, but it’s better to be safe than sorry.

There are a few places in the world where you can witness square waves. One of them is the French Island of Re, located off the coast of La Rochelle. This island is known for its beautiful square waves and attracts many tourists who come to admire them from a safe distance. Another spot is Cape Reinga in New Zealand, where the Pacific and Tasman Seas converge.

While square waves may be a rare sight, it’s important to remember that beauty can sometimes be dangerous. Always prioritize your safety and be aware of the potential risks when you’re near the water. Enjoy the beach, but be mindful of the conditions. Stay safe and have a great time!
