An amphidromic point is a no tide point in the ocean around which the tide crest rotates through one tidal cycle. This means that the water level at this point remains constant and does not experience any tidal change. Tides are higher at some points in the ocean, but this is not what defines an amphidromic point. Tidal datum displacement to the right or south and the concept of daily high tide with no low tide also do not apply to amphidromic points.
