A quick definition of mean high tide:
Mean high tide refers to the average height of all high tides over a period of 18.6 years. Tides are the rising and falling of seawater caused by the attraction of the sun and moon. They are used to measure the boundary of a shore. Neap tides are lower than average tides that occur during the first or last quarter of the moon, while spring tides are higher than average tides that occur during the new moon and full moon.
A more thorough explanation:
Mean high tide refers to the average height of all high tides over a period of 18.6 years. It is used to measure the upland boundary of a shore.
For example, if a beach has a mean high tide of 5 feet, it means that on average, the highest point the tide reaches is 5 feet above the shore.
Understanding mean high tide is important for coastal development and management, as it helps determine where structures can be built and where erosion may occur.
