Most coastal areas, with some exceptions, experience two high tides and two low tides every lunar day (Ross, D.A., ). Almost everyone is familiar with the concept of a hour solar day, which is the time that it takes for a specific site on the Earth to rotate from an exact point under the sun to the same point under the sun.

Three basic tidal patterns occur along the Earth’s major shorelines. In general, most areas have two high tides and two low tides each day. When the two highs and the two lows are about the same height, the pattern is called a semi-daily or semidiurnal tide. If the high and low tides differ in height, the pattern is called a mixed semidiurnal.

Aug 01,  · Due to the cyclic rotation of the earth and moon, the tidal cycle is 24 hours and 52 minutes long. During this time, any point on the earth's surface experiences two high tides and two low tides. The tidal bulge that occurs during high tide in the world ocean follows the revolution of the moon, and the earth rotates eastward through the bulge.

Tides that happen twice a day are called semidiurnal. Because the Earth rotates in the same direction as the Moon, the cycle is actually slightly longer than a day at 24 hours and 50 minutes. Tides and the Moon While the Sun and the rotation of the Earth both have some tidal impact, the location of the Moon has the biggest affect on the tide.

The tides create a useful natural clock for humans and animals alike. A fish called grunion times its spawning cycle around the tides. Grunion always spawn on land right after the peak of the highest tide in a series of steadily higher tides. If the fish were to spawn while the tide was still rising their eggs would be carried out to sea.
