Do freak waves really exist?

For a long time, it was believed that tales of enormous solitary waves appearing out of nowhere were merely the product of sailors’ imaginations: stories of crashing giant waves simply captivate listeners.

About forty years ago, scientific proof that such waves actually exist was finally obtained for the first time. In 1995, the Norwegian offshore platform “Draupner” recorded a gigantic, nearly 26-meter-high rogue wave in the North Sea.

Today we know: Giant waves—also known as freak waves or rogue waves—are rare but real phenomena. Such waves are often between 20 or even over 30 meters high—significantly higher than the surrounding waves—and do not appear to curve harmoniously, but rather rise almost as steeply as a wall. This, combined with the fact that they appear out of nowhere, makes freak waves one of the most dangerous natural phenomena at sea. They can severely damage ships or even cause them to sink.

Ocean mapping is becoming increasingly detailed and precise, and there are research projects underway to use the collected data and AI analysis to predict where such a wave might form. Even if the forecast is only accurate to a few minutes, it makes a difference for the ship’s crew whether they are completely caught off guard by a wall of water or can prepare for it both mentally and physically.
