Tides and water level data

Water level data are available through an API (Application Programming Interface), which makes it possible to extract data and integrate them with your own systems.

Older data, from before the end of the 1980s, can be fetched through the Copernicus Marine Service. We advise you to collect recent data from the Norwegian Mapping Authortiy’s API to ensure all changes are handled.

Terms of use

The API is open for everybody and does not require registration, but the Norwegian Mapping Authority, Hydrographic Service must be credited, since we are licensee of the data.

The use of the data are licensed through Creative Commons Attribution 4.0 international (CC BY 4.0).

Please send us feedback at kundesenter@kartverket.no, especially if you use the data to create new services or apps.
