Editing Sneaker wave (section)

==Hazards==

The unpredictability of sneaker waves and their tendency to arrive suddenly after lengthy periods of gentle, lapping waves makes it easy for them to surprise unwary or inexperienced beachgoers;<ref name=nwssneakerwaveslogrolls/> because they are much larger than preceding waves, sneaker waves can catch inattentive [[human swimming|swimmers]], waders, and other people on beaches and ocean [[Jetty|jetties]] and wash them into the sea. The force of a sneaker wave's surge and the large volume of water rushing far up a beach is enough to suddenly submerge people thigh- or waist-deep, knock them off their feet, and drag them into the ocean or trap them against rocks.<ref name=nwssneakerwaveslogrolls/> Many coastlines more prone to sneaker waves lie in colder parts of the world where beachgoers tend to wear heavier clothing; the amount of [[sand]] and [[gravel]] in a sneaker wave can quickly fill such clothing and footwear such as boots with [[sediment]] that weighs a person down as he or she is swept up a beach and then back into the sea, increasing the chances of drowning.<ref name=nwssneakerwaveslogrolls/> Floating and rolling logs in a sneaker wave also pose a danger, as they can badly injure people as well as pin people down when they come to rest, and it can be difficult or impossible to move such a log before a person pinned by it drowns as later waves arrive and fill the person's lungs with water and sediment.<ref name=nwssneakerwaveslogrolls/>
