The moons gravity pulls water closer or farther away
"Neap Tides".
Tide is the answer.
A full tidal cycle consists of two high tides and two low tides, occurring roughly every 12 hours and 25 minutes. This cycle is driven by the gravitational forces of the moon and sun acting on the Earth's oceans. The height and timing of the tides can be influenced by factors such as the phase of the moon, the sun's position, and local geography.
It takes 24 hours to go through a cycle of tides because the moon cause these tides and it takes a day to revolve around the earth.
Minimum tides are also known as low tides. It's the lowest a tide will get in the cycle of highs and lows.
Semidiurnal tides have two high tides and two low tides of nearly equal height each day, while diurnal tides have one high tide and one low tide per day. Semidiurnal tides are more common globally, while diurnal tides are more common in certain locations.
In Southampton, as in many other coastal areas, there are typically two high tides and two low tides each day. This phenomenon is due to the gravitational pull of the moon and the sun on Earth’s oceans. The timing and height of these tides can vary based on the lunar cycle, weather conditions, and geographical features.
There are typically two spring tides in a lunar cycle. This occurs when the gravitational forces of the Sun and Moon align, causing higher than normal high tides and lower than normal low tides.
because of wind
Semidiurnal tides are tides that have two high tides and two low tides of about the same height each day. This pattern occurs because the Earth experiences two high and two low tidal bulges due to the gravitational forces of the moon and sun.
High tides are typically about 12 hours and 25 minutes apart in a typical tidal cycle.
Spring and neap tides come twice a month.
