As of today, past peak, season runs to ~December 31. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Mont-Saint-Michel experiences some of the largest tidal ranges in Europe.
When a new or full moon coincides with lunar perigee and the spring or autumn equinox, the bay sees 'grandes marées' where water rises rapidly and can exceed 12 meters.
These events are predictable by tide tables but vary in exact height year to year.
