What Are Tides and How Do They Work?
The Moon and its gravitational pull cause both high and low tides. As the Earth rotates, the Moon’s gravity pulls on different parts of the planet, even the land in very small amounts. While the Moon cannot easily pull the land of the Earth, water has a much easier time moving around and is naturally drawn in the direction of the Moon, causing water to “bulge out” on the sides of the Earth that are closest to and furthest from the Moon. This is called the tidal force, and those opposite “bulges” of water are high tides. Tides are one of the most reliable phenomena in the world. As the sun rises in the east and the stars come out at night, we know that ocean waters will regularly rise and fall along our shores.
How Frequently Do Tides Rise
While everyone is familiar with the standard 24-hour solar day, high and low tides operate on a lunar day which is 24 hours and 50 minutes long. The lunar day is 50 minutes longer than a solar day because the moon revolves around the Earth in the same direction that the Earth rotates around its axis. That means it takes the Earth an extra 50 minutes to “catch up” to the moon.
Because the Earth rotates through two tidal “bulges” each lunar day, most coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur every 12 hours and 25 minutes apart. It takes 6 hours and 12.5 minutes for water at the shore to go from high to low or from low to high.
To set your Tidal Clock
The tide indicator hand should be set to high tide when the next high tide in your area occurs. As a general rule, it is best to set the tide hand at high tide during a full or new moon. If this is not possible, we suggest you check the reading of the tide hand at the next full or new moon.
Users, other than the Atlantic cost will need to adjust the clock from time to time depending on the local tide table.
