The wave period is the time it takes for two consecutive wave crests or troughs to pass a fixed point. Therefore, all that is needed to measure the wave period is a stopwatch to time the interval between two successive wave crests or troughs passing a fixed point on the shoreline. The other equipment, such as a measuring tape or meter stick, is not necessary for measuring wave period.
