High tides

Who hasn’t heard of Saint-Malo’s great tides?

More than just a spectacle, the tides punctuate the daily lives of the people of Saint-Malo. Here, the sea offers you a different landscape every moment, swept back and forth twice a day by the tide.

When there is a full moon or a new moon, the attraction is at its peak. Tidal coefficients generally exceed 100. Fishermen and oyster farmers bustle about between ebb and flood, always bearing 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 eagerly awaited by fishermen on foot, as the sea withdraws particularly far. But they are also greatly feared by people living near the seaside, as there is a frequent risk of flooding at high tide.

What if you only had to walk a few steps to stumble across a treasure?

At low tide, a preserved biodiversity can be discovered, Saint-Malo and the Bay of Mont-Saint-Michel offer foot fishing enthusiasts one of the world’s greatest playgrounds, thanks to very high coefficients, which can exceed 100 at the equinox period. Put on your boots and go fill your lungs with iodine and your bucket with delicious gems.
