This is an artist rendition of a rogue wave. It is hard to get a good photo of a rogue wave simply because they ‘come out of nowhere’ and without warning. Mariners have spoken of ‘monstrous walls of water’ that appear from nowhere in the open seas and are impossible to steer around them. However, physical oceanographers have disregarded such mythical stories from mariners and suggested that rogue waves build up gradually and have narrow crests relatively. Furthermore, lack of data, measurements, and observations of rogue waves did not benefit the argument of the mariners.
Life on the open sea is not for the faint of heart. Although rare, waves such as the one pictured below are wild and unpredictable; they are rogue. Since man has sailed across the seas, they have told legends of these waves that seemed to defy logic. Sailors have described them as enormous mountains surrounded in a blanket of water. In a typical swell, an average wave crest can stand somewhere around 6 meters tall (≈20 ft). However, every now and then, ship-men will encounter rogue waves at least twice the size, oftentimes as high as 23 meters tall (≈75 ft) and some taller depending on the ferocity of the storm. These waves are known to ruin shipping cargo, throw crew-members overboard, and even capsize shipping vessels.
