Estran : Marées de ta Plage

The tide at YOUR beach — not the one at the neighboring port.

Estran calculates the tide directly on your phone, for over

2,800 beaches in mainland France and its overseas territories. No servers: the tide,

coefficient, sun, and moon work even in airplane mode, deep

in a cove.

HONEST BY DESIGN

Heights are astronomical predictions: the weather can change them. Estran indicates the reliability of each beach and does not replace official navigational charts.
