King Tides are the highest tides of the season. They are a natural occurrence, not generated by any strong storm, so these high tides are predictable. But if you are unfamiliar with exactly how a high tide works, let’s go back to the basics.

A tide is the movement of water across the surface of the earth. The water moves due to gravitational forces. These forces are generated by the alignment of the moon and the sun and the rotation of the earth. These combined effects cause the rise and fall of sea level along our coast. Also worth noting, with the highest tides of the season, we will experience the lowest tides as well!
