 Grande marée

 Mont Saint-Michel spring tides 2027 
=====================================

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. From January to April 2027 there are 17 spring-tide days, with a peak coefficient of 110.

The Office de Tourisme publishes the 2027 island days in December, so none of these dates carries the island flag yet. Every published spring-tide day of 2027 is listed below, grouped by month, with its high tide times and coefficient.

 Source and accuracy. Predictions: SHOM, 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. Always verify on site before crossing.
