Spring Tides : an exceptional maritime phenomenon

01Jan 31Dec

2019 : Spring tides dates in la Manche


Come to Normandy during a period of full moon and observe the Spring tides, a phenomenon unique in Europe.

These are visible when the tidal range is above 90; it will be the case for a few days each month between February and December.


Come and enjoy the magic of the spring tides
and (re)discover Mont Saint-Michel surrounded by water,
go fishing or admire the tidal bore.


There’s so much to do and the show is spectacular. You might even get the chance to see the access road to Mont Saint-Michel underwater!

Must do and see during Spring Tides :

> For a few hours or a whole night, let yourself be trapped in the village of Mont Saint-Michel.

> Put your wellies on and go out with a rake to collect dog cockles, razor-shells and clams. Please be reminded that rockpooling is regulated in our order to preserve natural resources.

> Enjoy long walks on the foreshore, a portion of sand which is revealed only during Spring Tides.

The tidal phenomenon

Each day, the sea level varies with the phenomenon of tidal force.
But depending on the position of the sun and the moon in relation to the Earth, the tidal range can be more or less extreme. When a full moon lines up with the sun and the Earth, the attraction is so strong that it results in the spring tide, when the tide’s range is at its maximum.

Combined with its favourable geographical location, the Bay of Mont Saint-Michel is the perfect place to discover the spring tides!

Spring Tides are also the occasion to observe a spectacular natural phenomenon: the Tidal Bore. This wave of about 50 cm high rushes into the Bay of Mont Saint Michel offering spectators and kayakers a unique moment.
Best spots to observe the bore :
> La pointe du Grouin du Sud (near Vains),
> Pontaubault,
> Mont Saint-Michel.
