diurnal tide

A diurnal tide refers to the pattern where there is essentially one high tide and one low tide each day. This occurs because the Earth's rotation and the gravitational pull of the moon create a single, daily cycle of water movement along certain coastlines. In regions experiencing diurnal tides, the water level rises to a peak once, then falls to a low point once within a 24-hour period. This pattern contrasts with semi-diurnal tides, which have two high and two low tides each day. The diurnal tide pattern is characteristic of specific geographic locations influenced by local gravitational effects and coastline shape.
