Tide tables

From Glossary of Meteorology



tide tables

Annual tabulations of daily predictions of the times and heights of high water and low water at various places.

Such tables are constructed from astronomical data and from the results of harmonic analyses of previous observations at the desired point. They are compiled and issued by national hydrographic authorities, for example, the U.S. Coast and Geodetic Survey. The heights in tide tables are usually measured from chart datum rather than mean sea level.
