For a breath of fresh air, come in spring and fall, enjoy the incomparable spectacle of tides of the Emerald Coast.


Grande marée

Twice a day , every 6 hours , the sea is driven by a force which the sun and moon rule the show , the beach and the rocky coast of Brittany is covered and uncovered .
Tides are daily but they always have something special !

With the tidal coefficient , professionals and amateurs can get an idea of the importance of the tide and have no surprises when the sea rises. This " scale" is between 20 ( lowest dead water) and 120 ( bright equinox water). From the coefficient 95 , it is high tide .

The highest tides in Europe

On the Emerald Coast , the configuration of the coast has a great influence on the importance of tides. If the Bay of Saint -Malo is proud to be the scene of the highest tides in Europe , this is due to its geographical location.

When the Atlantic Ocean, huge mass of water rushes into the mouth what the Channel , the wave of the sea then happens very fast and very strong.

The tidal range - the difference between the high seas and sea bass - is on average more than 12 meters around the walled city . An exceptional phenomenon when we know that in the Landes region , the tidal range is 5 m and the global average is 2 m !

In 2014 , there will be 87 days of spring tides , 42 to over 100 !

Understand the phenomenon

Tide , daily movement of the sea, is a universal phenomenon.

Our ancestors have long believed that this event was governed by the gods or by dark forces .

The law of universal gravitation Newton and the work of scientists such as Laplace and Poincaré have indeed proved from the seventeenth century that it was a story of strength : that of the Moon and Sun on the Earth.

The Moon is a magnet on the oceans. Its gravitational pull on Earth is twice higher than that of the Sun, its proximity .

Their actions are combined in different ways according to their positions :

The tides , also known as the spring tides , occur when the full and new moon, when the Moon and Sun are in alignment with the Earth. They thus draw heavily .

When the Moon and Sun form a right angle with the Earth ( during the first and last quarter ) , they are neap tides
