There are several terms used to describe variations in sea level during the daily tidal cycle. This is a term commonly used in maritime navigation, fishing activities and coastal activities.

Big Tide:

High tide is when sea water reaches its highest height in the daily tidal cycle. This occurs when the Moon and Sun are in a straight line with the Earth or close to that straight line. At this time, the gravitational pull of the Moon and the Sun strengthens each other, causing sea water to rise to its peak. Big high tides usually occur twice a day.

Dead Tide:

Dead tide is when sea water reaches the lowest level in the daily tidal cycle. This occurs when the Moon and Sun form a 90 degree angle with the Earth or close to that angle. At this time, the gravitational pull of the two offset each other, causing the sea water to drop to its lowest level. Dead tide also occurs twice a day.

Big Pushing Water:

The big water push is when sea water starts to rise from the lowest height to the highest height. This is the period when sea water continues to rise after reaching dead tide. The large pushing of the water continues until it reaches high tide.

Small Pushing Water:

Small water thrusts are when sea water begins to fall from the highest level to the lowest level. This is the period when the sea level continues to decline after reaching high tide. The small thrust of the water continues until it reaches dead tide.
