tidal cycles
Sea level fluctuations
Tidal cycles are the recurring patterns of rising and falling sea levels caused by gravitational forces from the moon and sun.
Most coastlines experience two high tides and two low tides daily, though some locations have only one.
The cycles follow predictable rhythms—daily, monthly, and seasonal—that govern marine ecosystems, fishing schedules, and coastal navigation: The harbor is only accessible at certain points in the tidal cycle.
