French spring tides 2027: the tide coefficient calendar, month by month

Every spring-tide series of 2027 with the coefficient of each high tide. 16 series above 90, 6 of them above 100; the biggest: 112, on Thursday September 2, 2027.

France measures the size of each tide with a coefficient from 20 to 120. Above 90 it is a spring tide; above 100, a very big one: the sea rises higher and falls lower, the shore uncovers far at low tide and currents get stronger. In 2027 the biggest come in late January, late February, late March, early August and September.

The biggest tides of 2027

Take care at low tide: with a big coefficient the sea comes back fast and can cut off the way back. Tide times change from one harbour to the next: check YOUR harbour before heading out, in Tide It, with the curve, 12 months ahead and an alert when the coefficient passes your threshold.
