The waves from each system can meet in the middle at perpendicular angles. These winds can come from two different weather systems, each far away from each other. But what happens when the wind suddenly shifts direction? The new wind causes waves as well. This formation is known as a “cross sea.” Waves are usually made when the wind blows in one direction over the surface of the water. It looks like a grid on the surface of the water. Normally you’d just see waves coming in parallel to the shore, right? But what if there were also waves moving perpendicular to the shore? You’d see the waves intersecting each other at roughly right angles. Imagine that you have a bird’s eye view and you’re looking down at the ocean. The next time you're planning a trip, consider the Île de Ré, a small island off the west coast of France. But I’m still looking forward to my beach trip. But eventually, one of the wave patterns will dissipate and it becomes safe again. They look so cool-I can’t wait to go swimming in them!ĭ: Wait! Don’t do that! Cross seas are dangerous: they indicate strong, uneven currents beneath the surface. Y: Though the phenomenon can happen just about anywhere, the Île de Ré is famous for its square waves. That’s a cross sea, and yeah, it does make the waves look square! It looks like a grid on the surface of the water.ĭ: Oh, I get it! You’re talking about a “cross sea.” Waves are usually made when the wind blows in one direction over the surface of the water. Y: Imagine that you have a bird’s eye view and you’re looking down at the ocean. It’s got sun, sand, … and square waves!ĭ: I’m having a hard time picturing that! What do you mean, Yaël? I think I’ll go the Île de Ré, a small island off the west coast of France.
