High water, coefficients, and the moments the bay transforms — so you can arrive for the view, not just the timetable.
Times in Europe/Paris. Spring tides (coef ≥ 95) are the days the bay feels most dramatic.

Tap any day for highs, lows, and a suggested arrival. Peak coefficient for each month is shown in the strip below.
Predictions are an independent harmonic model trained on free REFMAR Saint-Malo tide-gauge observations, adjusted for the Mont Saint-Michel bay. They are typically within about 5–10 minutes of public SHOM-based tables for 2026, and are not an official SHOM product. Weather (wind, pressure) can shift real water levels. Always follow on-site signage before walking on the sands.
The French scale of tidal strength. Around 95 and above, the bay’s character changes — emptier lows, faster rises, stronger spectacle.
For the classic “water returning to the rock” view, be in place 90–120 minutes before high tide — earlier on spring tides.
Only the strongest cycles, plus weather, make the Mont feel fully surrounded. We flag coef ≥ 102 as exceptional; confirm locally.
