What is a NOAA tide table?

This image shows daily tide predictions for Eastport, Maine, for January-February 1867. This page is from the first edition of a national annual tide table publication created in 1866 by the U.S. Coast Survey, a predecessor of NOAA.

Tide tables provide the times and heights of high tide and low tide at more than 3000 locations along the U.S. coastline. NOAA’s Center for Operational Oceanographic Products and Services and predecessor agencies have produced annual tide tables for more than 150 years. These annual publications were produced in print form from 1865 to 2020 and were superseded by electronic predictions beginning in 2021. NOAA tide tables offer predictions on a daily, monthly, or annual basis.

Tide tables are different from tide charts. A tide chart is a printed map showing water levels on an hourly basis throughout a bay or an estuary at a particular point in time. Such charts were only available for only a few locations around the nation. However, these printed tide charts have been superseded by modern, digital hourly forecast models and graphical products.
