Understanding Semi-Diurnal Tides: Causes, Characteristics, and Impacts

Semi-diurnal tides are tides that have one high and one low tide each day, but the difference in water level between the two tides is not as extreme as it is with diurnal tides. This type of tide pattern is typical for many coastal areas around the world, including the Atlantic and Pacific Oceans.

In a semi-diurnal tide cycle, there are two high tides and two low tides each day, but the difference in water level between the high and low tides is not as great as it is with diurnal tides. The high tides are typically higher than the low tides, but not as high as the high tides in a diurnal cycle.

Semi-diurnal tides are caused by a combination of factors, including the gravitational pull of the Moon and Sun, the rotation of the Earth, and the shape of the coastline. They are an important factor to consider for coastal communities and marine ecosystems, as they can affect the movement of water and the distribution of marine life.
