[Mont Saint-Michel Tides](https://montsaintmicheltides.com) › Spring tides 2026 Grande marée Mont Saint-Michel spring tides 2026 ===================================== A spring tide, or grande marée, is a cycle with a tidal coefficient of 95 or above, when the Bay of Mont Saint-Michel transforms: the sea retreats kilometres at low water, then refills fast enough to make the rock feel cut off. In 2026 there are 48 such days, peaking at coefficient 105. The strongest spring tides cluster around the equinoxes, when the Earth, Moon, and Sun line up most precisely with the equator and the lunar (M2) and solar (S2) tidal forces reinforce each other. In 2026 the vernal equinox falls on March 20, 2026 and the autumnal equinox on September 23, 2026; the grande marée dates closest to each are the highest of the year. On 3 of these days the water runs high enough that the 2014 footbridge submerges and the Mont becomes a true island again. Every spring-tide day of 2026 is listed below, grouped by month, with its high tide times and coefficient.
