Tides are an eternal spectacle, at high tide as well as at low tide.
The spectacle of high tides is always special. To check them out, we recommend you look for tidal coefficient (tidal range indicator) above 95 on our pages dedicated to Highest spring tides.
Every day, like a metronome, the sea rises and falls with amplitudes that can reach 14 metres (47 feet). Mythology tells us that the tide was caused by the breathing of a sea monster. Newton came to understand the origin of the phenomenon at the end of the 17th century: the tides, equal to the movement of the stars, follow the law of gravitation.
The reciprocal attraction of the Moon, and to a lesser extent of the Sun, causes the movement of the waters. The mass of the Earth attracts the Moon and allows it to remain in orbit. Conversely, the mass of the Moon creates a force that attracts the Earth and the oceans around it: we call it the force of gravity.
Thus, the sea - like all particles of matter on the surface and inside the Earth - participates in this movement of attraction. The closer these particles are to the Moon, the more significant their displacement.
This tidal force is also influenced by the centrifugal force exerted by the rotation of the earth on itself.
The influence of the tidal effect caused by the moon slows the rotation of the Earth over time: the length of the day increases by 0.00164 seconds per century. This slowdown is slight but regular. It is attributed to the dissipation of energy exerted by the friction of the tides.
Amplitude: The difference between the height of a high or low water and the mean level. This term is often misused to refer to tidal range.
Current: Horizontal movement of seawater particles, characterized by direction and velocity.
High Water: The highest level reached by the sea during a tidal cycle.
Low Water: The lowest level reached by the sea during a tidal cycle.
Tidal coefficient: Allows you to quantify the importance of the tide. It varies from 20 to 120. A large tide or spring tide implies a large tidal range: the sea rises high and falls very low.
Tide: A periodic movement of sea level due to the effects on liquid particles of the gravitational attraction of the Moon and Sun.
Tidal range: The difference in height between a successive low tide and high tide.
