The water level at a beach typically rises and falls throughout the day due to a natural phenomenon known as tides. Tides are caused by the gravitational forces exerted by the Moon and the Sun on Earth's oceans. While the Moon has a greater influence on tides due to its proximity, the Sun's gravitational pull also contributes to the overall tidal pattern.
There are two main types of tides: high tides and low tides. During a high tide, the water level at the beach rises, while during a low tide, it recedes. The timing and height of tides can vary depending on several factors, including the location of the beach, the shape of the coastline, and local geography.
The rise and fall of tides occur in a cyclic pattern, with approximately two high tides and two low tides occurring within a 24-hour period. The time difference between successive high or low tides is around 12 hours and 25 minutes. As a result, the water level at a beach rises and falls throughout the day.
During the night, the water level at the beach may rise due to the occurrence of a high tide. However, it's important to note that the exact timing of high tides can vary from one location to another. Therefore, high tides can occur at any time during the day or night, depending on the specific tidal patterns of the region.
