[Mont Saint-Michel Tides](https://montsaintmicheltides.com) › 2026 tide calendar Browse by month Mont Saint-Michel 2026 tide calendar ====================================== Twelve months of tides for Mont Saint-Michel in 2026. The bay sees 48 spring-tide cycles (coefficient 95 or above) over the year, and on 3 of those days the causeway submerges and the rock returns to being a true island. The peak coefficient of 2026 reaches 105. The strongest cycles 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 spring tides closest to each date are the ones to mark in your calendar. Each month below carries its own daily calendar, the days the Mont becomes an island, and the highest coefficient of the cycle.

Predictions: SHOM (n° 2025-209), reference port Saint-Malo, distributed by the Office de Tourisme Mont Saint-Michel, Normandie. Times are in legal French time (CET in winter, CEST in summer). Strong onshore winds and low atmospheric pressure can raise actual water levels above prediction. The Tourist Office classifies "Mont becomes an island" days using local bay dynamics, not a simple coefficient threshold.
