Davisian Cycle
Davisian cycles describe the natural up-and-down pattern of a coastal tide, caused primarily by the gravitational pull of the moon and sun. Typically, there are two high tides and two low tides within a roughly 24-hour period. The cycle involves a primary high tide, a low tide, and then a secondary high tide, followed by a secondary low tide. External factors such as the shape of the coastline and local geography can influence the exact timing and height of these tides. This cycle helps us understand and predict daily tidal patterns critical for navigation, fishing, and coastal management.
