King tides are a normal occurrence once or twice every year in coastal areas. In the lunar month, the highest tides occur roughly every 14 days, at the new and full moons, when the gravitational pull of the Moon and the Sun are in alignment. When the gravitational pull of the Sun and Moon are combined, you get more extreme high and low tides.

During these Moon phases, the gravitational forces of the Moon and the Sun combine to pull the ocean’s water in the same direction. Newton's Law of Gravitation provided a quantitative understanding of that association. How many hours pass between a high tide and a low tide? If the two highs and lows differ substantially, the pattern is called a mixed tide.
