High tides in Saint-Malo

More than a spectacle, the tides punctuate the life of the Malouins on a daily basis. Here, the sea offers you a different landscape at every moment, swept twice a day by the comings and goings of the tide.

During the full moon or the new moon, the attraction is at its peak. The tidal coefficients generally exceed 100. Fishermen and oyster farmers busy themselves between flood and ebb, always keeping in mind the time of the tide.

Every six months, close to each equinox (March-April and September-October), the tides are even stronger. These are the famous equinox tides so awaited by fishermen on foot, because the sea recedes particularly far. But they are also very feared by residents of the seaside because the risk of flooding at high tide is frequent.
