Beware the beauty: Dangerous square waves lure tourists to Île de Ré
Although they may seem beautiful, square waves can be hazardous. These so-called square waves can be observed on open waters and near the shore. There is a location in Europe where they appear more frequently than in other parts of the world.
Square waves make an incredible impression in photographs and look even more spectacular in person. But where do these unusual formations come from?
Square waves in Europe
The phenomenon, resembling a chessboard on the water, is created by the interaction of wind with the sea surface, forming a grid effect of squares.
Despite being visually fascinating, square waves are as dangerous as tides. Powerful currents occur in the spaces within their structure. Such waves often reach several yards, frequently causing ships to capsize. When these waves appear, leaving the water becomes nearly impossible.
Square waves as an attraction on an island in Europe
Interestingly, Europe is a unique place to observe this phenomenon regularly. It is the French island of Île de Ré, situated off the western coast of France. Every year, it attracts many tourists eager to witness these famous square waves firsthand.
You can reach Île de Ré from La Rochelle by taking a route across a bridge approximately 2 miles long. To safely admire this phenomenon, it is best to go to the lighthouse. The view of the waves from the beach is impressive, and in good weather, you can climb to the top of the lighthouse.
