![]() Tides are mostly semi-diurnal (meaning two high waters & two low waters each day), or diurnal (meaning one tidal cycle per day). But in some locations the moments of slack tide differ quite a lot from those of high and low water. Slack water normally happens near high water and low water. Then the tide reverses direction and is said to be turning. When a tidal current ceases it is called slack water or a slack tide. Tides produce currents known as tidal streams. The water stops falling, reaching low tide.Sea level falls over several hours, revealing the intertidal zone ebb tide.The water rises to its highest level, reaching high tide.Sea level rises over several hours, covering the intertidal zone flood tide.Tide changes proceed over several stages: The Ocean Isle Beach area experiences four tides a day, two high and two low each day.While tides are usually the largest source of short-term sea-level fluctuations, sea levels are also subject to forces such as wind and barometric pressure changes, resulting in storm surges, especially in shallow seas and near coasts. Tides are when sea level rises and falls due to the combined effects of forces of gravity exerted by the Moon and the Sun and also the rotation of the Earth. They are not certified to be correct, and they do not incorporate the effects of tropical storms, El NiƱo, seismic events, continental drift, or changes in global sea level.
