Other phenomena unrelated to tides but using the word tide are rip tide, storm tide, hurricane tide, and black or red tides. Many of these usages are historic and refer to the earlier meaning of tide as a portion of time, a season.

From the highest level to the lowest: 1  Highest Astronomical Tide (HAT) – The highest tide which can be predicted to occur. 2  Mean High Water Springs (MHWS) – The average of the two high tides on the days of spring tides. 3  Mean High Water Neaps (MHWN) – The average of the two high tides on the days of neap tides.

From the highest level to the lowest: 1  Highest Astronomical Tide (HAT) – The highest tide which can be predicted to occur. Note that meteorological conditions may add extra height to the HAT. 2  Mean High Water Springs (MHWS) – The average of the two high tides on the days of spring tides.

Tide - Characteristics. 1  Tide changes proceed via the following stages... 2  Sea level rises over several hours, covering the intertidal zone; flood tide. 3  The water rises to its highest level, reaching high tide. 4  Sea level falls over several hours, revealing the intertidal zone; ebb tide. 5  The water stops falling, reaching low tide.

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of Earth. The times and amplitude of tides at any given locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry. Some shorelines experience a semi-diurnal tide—two nearly equal high and low tides ...

Tidal phenomena are not limited to the oceans, but can occur in other systems whenever a gravitational field that varies in time and space is present. For example, the solid part of the Earth is affected by tides, though this is not as easily seen as the water tidal movements.

1The alternate rising and falling of the sea, usually twice in each lunar day at a particular place, due to the attraction of the moon and sun. 1.1 The water as affected by the tide. 1.2 A powerful surge of feeling or trend of events.

The Highest Astronomical Tide is the perigean spring tide when both the sun and moon are closest to the Earth.

The times and amplitude of tides at any given locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing).

In Maine (U.S.) low tide occurs roughly at moonrise and high tide with a high moon, corresponding to the simple gravity model of two tidal bulges; at most places however, moon and tides have a phase shift.
