Currents

Currents information sourced from the British Admiralty data base is provided for Surface Currents and Tidal Currents.

Surface Currents

Surface currents are seasonal currents that can run at up to five knots in places. These surface currents are represented by black arrows showing strength and direction for all parts af the world that Admiralty Current data exists.

The images below show how Navigator displays currents in practice. This data was taken from the Northeast cost of Africa. Note the difference in directions of currents between January and June.

Both images below can be enlarged by clicking on them.

Tidal Currents

Tidal currents are the currents caused by changes in tide height. This information can have a significant affect on passage planning where the current is strong. The information is represented by blue arrows showing strength and direction and is displayed hourly for areas of the world that Admiralty Tidal data is available.
