Sea Surface Height

Deviations of sea surface height above or below mean sea level generated by the tides, commonly referred to as tidal elevation. Caused by the gravitational pull of the moon (and to a lesser extent of the sun), the tides are the most predictable oceanic motions. Topography of the ocean floor, or bathymetry, creates variations in the range and timing of the tides across Hawaiʻi, with an overall maximum tidal range of roughly ±50 cm (19.7").
