tidal current tables Generically this means any set of tables that give the predicted times of slack water and the predicted times and velocities of maximum current flood and ebb for each day of the year. Prior to 2021, NOAA published two books of annual tidal current predictions, one for the Atlantic Coast of North America and one for the Pacific Coast of North America and Asia. These included daily data from numerous reference stations (now called harmonic stations) along with an extensive table (called Table 2) of time and speed corrections for 1,816 (Atlantic Coast) and 1,308 (Pacific Coast) subordinate stations. The 2020 Table 2 current corrections are still (as of 2023) in print from third party printers, despite the fact that much of the data are no longer valid, and none is certified by NOAA. Other data historically included in these tables, however, can still be useful such as rotary current forecasts for coastal waters, and tables for interpolating the predictions. Links to the last official printings that include these extra data are at starpath.com/navbook. Our primary source for tide data is now www.tidesandcurrents.noaa.gov, at which site we can print an annual set of tide tables for any station. It takes 4 pages per station.
