API for 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.

Documentation and user guide for the API are available at http://api.sehavniva.no/tideapi_en.html.

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.

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

Get Tidal Forecast on Your Website (widget)

We have developed a widget that makes it easy for you to show tide tables from Norway directly on your website, giving your visitors an updated tidal information directly from the Norwegian Hydrographic Services' database.

The widget is of value for marinas, local media, beaches, campsites and Norwegian coastal municipality eg.

How to use the widget:

  • On Se havnivå, search for the place/position you wish to collect a tidal forecast from.
  • Go to the right on the line that follows below the title with the place name or position, in your search result.
  • Click on the menu item </>.
  • Copy the code and place it in your own publishing solution.

The official publication giving the tide tables for the Norwegian coasts and Svalbard, "Tidevannstabeller for den norske kyst med Svalbard", is available for download as a pdf, free of charge.
