DMI forecast API for atmosphere, ocean and sea ice, free !

Updated 2025-01-04

DMI is the Danish Meteorological Institute and the
 Open Data API provides free and open access to DMI’s data.They are covering a pretty big area not just Denmark.

I'm maintaining the weather station for Domstens yacht club and have become really interested in weather "issues".

The actual use case for me is that I have to change the mooring, of our boat, if the water level exceeds 60 cm from normal. For several years I have been searching for a free forecast API so I can get an early warning when the water level rises.
