Statement

Surface tidal current predictions computed from statistical values obtained from hydrodynamic model gridded with a regular 500 m spatial resolution.

Those statistics are then interpolated/extrapolated every 15 minutes (cubic spline), and for each tide coefficient from 20 to 120 (linear). The statistical currents, initially referenced to Saint-Malo high tide, are then referenced to the hour requested by the user using the tide prediction service https://maree.shom.fr .
