Nautical Term: White cap

Definition of White cap

A white cap refers to the frothy white crest that forms on the summit of a wave. This phenomenon can be observed when the wind causes the waves to break, creating the distinctive white cap.

For instance, imagine a sailor navigating through rough waters. He notices the white caps appearing on the waves as the wind intensifies. Realizing the imminent danger of the worsening sea conditions, the sailor quickly decides to change course and find calmer waters.
