About spring tides
Spring tides correspond to periods when the coefficient exceeds 90. The gap between low and high tide is then larger than usual, exposing more of the shoreline. The strongest tidal ranges are typically observed along the English Channel, Brittany, and the northern Atlantic coast. Use the dates below to quickly identify the next favorable periods.

Understanding spring tides
What is a big tide?+
A big tide occurs when the coefficient exceeds 90.
Why do spring tides happen near the equinoxes?+

These configurations occur mainly around the equinoxes.
Where are the strongest tidal ranges in France?+
The largest tidal ranges are generally observed in:
- the English Channel
- Brittany
- the northern Atlantic coast
