During these Moon phases, the gravitational forces of the Moon and the Sun combine to pull the ocean’s water in the same direction. Similarly, a lunar day is the time it takes for a specific site on the Earth to rotate from an exact point under the moon to the same point under the moon. King tides occur during a perigean (when Moon is closest to Earth) spring tide (full and new moon); in other words, a full or new moon must co-occur when the Moon is closest to Earth in its elliptical orbit. For example, if high tide was 8ft above chart datum, and low is 2ft above chart datum – there is a 6ft difference, divided that into 12 even chunks; equaling 0.5ft per chunk. The tidal cycle lasts for 24 hours and 52 minutes. Since the Moon passes overhead about an hour later each day, it was long suspected that the Moon was associated with tides. Almost everyone is familiar with the concept of a 24-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.
