tidal cycle
Sea's daily pulse
A tidal cycle is the complete sequence of water level changes from one high tide through a low tide and back to high tide again.
Most coastlines experience two tidal cycles per day, roughly 12 hours and 25 minutes each, though some locations have only one.
The cycle results from gravitational forces of the moon and sun acting on Earth's oceans: The tidal cycle here makes morning the best time for clamming.
