The ocean produced a superwave that surprised all the surfers.
Superwave → It is formed from "super-" (meaning above or beyond) and "wave" (from Old English "wæf", meaning a moving ridge or swell of water). The word "superwave" refers to a wave that is larger or more powerful than normal waves.
Think of a wave that is 'above' ('super-') the usual size or strength — that's what a superwave means.
