Eight Immortals Cave conditions today
Wave height gauge: Overhead
How to read the two heights: Hs is the model's significant wave height; metres and feet are two units for that same Hs height (1 ft = 0.3048 m). Breaking-wave face height is an engineering estimate that applies a period-aware nearshore shoaling factor to Hs, so it is usually larger. It is not a unit conversion or an on-site measurement.
Overhead, clean waves, Offshore wind, good for practice.
