tide patterns
Sea level cycles
Tide patterns are the predictable cycles of rising and falling sea levels caused by gravitational forces of the moon and sun.
These patterns vary by location—some coasts experience two high tides daily (semidiurnal), others one (diurnal), or a mix.
Understanding tide patterns matters for navigation, fishing, and coastal planning: We checked the tide patterns before scheduling the beach cleanup.
