FAQ
Where to see the biggest tides in France?
In the Bay of Mont-Saint-Michel and Saint-Malo, during spring tides (coefficient 100–120). The equinoxes (March, September) give the biggest ranges.
Can the coefficient reach 120?
Yes: 120 is the top of the scale, reached at the greatest equinoctial springs. The sea uncovers to its fullest : beware the fast-returning tide.
