Square waves, in pictures and in person, command an awe-inspiring spectacle. How do these uncommon waves form? This checkerboard effect on the water's surface arises when waves intersect at right angles, influenced by wind direction. The result is an impression of a grid, made up of squares on the water.
The danger of square waves in Europe
Despite the allure these waves present, not everyone realizes that square waves, like tides, can be perilous. Incredibly potent ripping currents emerge within the checkerboard pattern formed on the water. These waves can reach considerable heights, up to several meters (around 10 feet).
Though an infrequent occurrence, these waves have caused numerous shipwrecks. Escaping from the grips of these waves once caught, is virtually impossible.
A European island attraction: square waves
Astonishingly, one place in Europe often witnesses this phenomenon. We are referring to Île de Ré, an island off the west coast of France. This location magnetizes countless tourists annually, all hoping to see the legendary square waves in person.
Île de Ré is accessible from the town of La Rochelle via a three-kilometer bridge (about 2 miles). To see this spectacle safely, you must get to the lighthouse. From here, the square waves can easily be observed from the beach. Weather permitting, a climb to the top of the lighthouse offers an even better view.
