The Federal Maritime and Hydrographic Agency of Germany (BSH) makes available GRIB files of its surface current predictions, which are suitable for use in navigation and regatta programmes.
As there has been an increase in demand for current predictions from leisure mariners, the BSH is planning to test whether its data are suitable for use by regatta participants or the leisure sector in general. Therefore, it is making available four GRIB files covering different regions of the North and Baltic Seas, which are updated daily and cover three-day prediction periods:

North Sea             48.5°N/004.0°W to 60.0°N/010.0°E, grid spacing 6 nm, resolution 1h.

Baltic Sea             52.0°N/010.0°E to  68.8°N/030.0°E, grid spacing 6 nm, resolution 1 h.

The above files contain the latest updated three-day current prediction. The data have been compressed using the compression programmes bzip2.
The BSH generates the data by means of a numerical prediction model which has been developed for up-to-date predictions of water levels and storm surges as well as drift and dispersion forecasts, e.g. in connection with oil spills. The model computes daily predictions of tidal currents, wind induced currents, and baroclinic currents. The computed surface current data are mean values of the currents in the uppermost 8 metres of the water column.

Legal notice
The BSH does not guarantee the functioning, completeness, accuracy or up-to-dateness of the predicted current data. Moreover, it will not be held liable for any technical failures or malfunctioning resulting from errors in data files or in the configuration of formats.
