What it is

DMI (Danmarks Meteorologiske Institut / Danish Meteorological Institute) is Denmark's national meteorological institute, part of the Danish government's public sector, with a history spanning nearly 200 years. The modern DMI was formed in 1990 through a merger of the original Meteorological Institute, the Aviation Meteorological Service, and the military Meteorological Office. The organization employs around 350–360 staff, with its main headquarters at Sankt Kjelds Gaard in Copenhagen, and additional service locations in Karup, Skrydstrup Air Base, and Nuuk, Greenland.

Core Features

For the general public, the website offers core services including local weather lookups, radar images (covering approximately 1.5 hours before and after the current time), 2-day and extended multi-day forecasts, satellite imagery (with 12 hours of historical data), and national weather outlooks. For professional use, DMI oversees all meteorological, climatic, and marine environmental work for Denmark proper, the Faroe Islands, Greenland, and the surrounding seas and airspace. This includes issuing severe weather warnings, providing ice condition information for Greenland, and developing future climate scenarios to support climate adaptation. The website also hosts a meteorological encyclopedia (Leksikon) and a science outreach section called Viden om vejr og klima. It participates in the development of data products for the EU Copernicus Climate Change Service, and offers English-language marine and ice condition forecasts.

Pricing

As a government public institution, all core content on the dmi.dk website, including weather forecasts, radar, satellite, and climate information, is completely free to access. It also offers free iOS and Android mobile apps. A portion of its meteorological data is available to the public through its open data program and API.

Pros and Cons

The biggest advantages are its official authority and quality-assured data. It covers multiple dimensions including weather, marine conditions, ice conditions, and climate research, with timely updates and valuable educational content. The drawbacks are that the service is explicitly focused on the Nordic region (Denmark, Greenland, and the Faroe Islands), so it has limited utility for users in other countries. In addition, the interface is primarily in Danish, with relatively limited English content.

Who It's For

It is best suited for local residents of Denmark and Greenland, maritime and aviation operators working in Nordic waters, journalists, and researchers focused on the Arctic and climate change.

Access from China

As a public government service, the website can be accessed directly from China without a VPN/proxy. For Chinese users, it primarily serves as an authoritative source of meteorological data or a reference for research.
