The beach's height variation is likely due to tidal changes influenced by the gravitational pull of the moon and sun. At 3 AM, high tide can cause the water level to rise, pushing sand and debris higher up the beach. By 9 AM, as the tide recedes to low tide, the water level drops, resulting in a lower beach height. This cyclical pattern of tides is a natural phenomenon that occurs approximately every six hours.
