Gravelly beach ridges, which are formed solely by swash processes, may accurately reflect
past wave conditions. The thickness (or height) of a gravelly beach ridge approximately
equals the height of wave inundation, which is the sum of the surge and wave run‐up. Their
ancient counterparts, if well‐preserved and identified, can be used to estimate palaeowave
conditions, which can later be converted to palaeowind intensities based on wind–wave
relationships. A technique is described for estimating the palaeowind speed in this paper …
