Local conditions and the official reference
Official coefficients
Official coefficients are not integrated into Mareloa. Consult the Shom portal for the relevant port.
View Shom tide predictionsTidal range is the height difference between consecutive high and low tides. Beach pages show this modelled quantity with times and sources.
The French coefficient uses a reference at Brest. It does not directly describe local height, currents or beach access. No coefficient is inferred here from local tidal range.
An astronomical prediction does not include every weather effect. Check local notices, restrictions and health information before a shore activity.
