A tide chart shows water levels on an hourly basis after high tide throughout a bay or an estuary at a particular point in time. Such charts are only available for a few locations around the nation. To obtain a print copy of NOAA tide tables and tidal current tables, visit NOAAs Tides and Currents website.
What are the tide and how are they used?
Gravity pulls the ocean towards the moon and high tide occurs. The bulge on the far side of the Earth is caused by inertia. The water moving away from the moon resists the gravitational forces that attempt to pull it in the opposite direction.
What is the importance of tide table?
A tide table becomes a major point of reference when a vessel tries to enter an inlet or a bay or an estuary for the purpose of docking. In water-parts like these, the presence of a low tide will moor the vessel even before it can dock at the dockyard and a high tide will disallow a vessel to dock at the required area.
Why do we use Tide tables?
A tide table provides daily high and low tide predictions. A tide chart shows water levels on an hourly basis after high tide throughout a bay or an estuary at a particular point in time. Such charts are only available for a few locations around the nation.
How do tides help humans?
Tidal data is also critical to fishing, recreational boating, and surfing. Commercial and recreational fishermen use their knowledge of the tides and tidal currents to help them improve their catches. Depending on the species and water depth in a particular area, fish may concentrate during ebb or flood tidal currents.
What are the benefits of tides?

What are the two effects of tide?
Tides affect coastal regions in different ways. High tides push large amounts of water far up onto beaches and leave the sand and sediment mixed with the water behind when the tide goes out. Therefore, tides transport sand and sediment and shape shorelines. Tides feed estuaries.
