An interactive weather map for Denmark, built only on official DMI forecasts. Live at vindy.dk.
Weather maps like Windy, Ventusky and Zoom Earth are lovely to use, but none of them show DMI's model — the one Denmark's own forecasts are based on. Vindy does: every forecast layer comes from DMI's HARMONIE model at 2 km detail over Denmark, updated every three hours and reaching 60 hours ahead. Radar and satellite imagery come from EUMETNET and EUMETSAT. It is a private, non-commercial hobby project.
- Forecast layers: wind, gusts, rain, accumulated rain, temperature, dew point, cloud cover, low clouds, pressure, humidity, visibility, thunderstorms (CAPE) and waves
- Oversigt: temperature with radar on top, continuing with the rain forecast for hours the radar doesn't reach
- Observations: European radar composite and satellite imagery for the last 3 hours, plus live measurements from DMI's stations
- Overlays: animated wind and wave particles, isobars with highs and lows, automatically derived weather fronts, forecast values at towns, and a value grid
- Point forecast: click anywhere for an hour-by-hour meteogram, including waves at sea
- Export: save the map as an image (PNG) or as an animation (MP4 or GIF) over a period you choose
- Progressice Web App: works offline for the interface, with shortcuts to radar, wind and rain
- Search for Danish places and addresses, and shareable links like
/wind/55.68,12.57,9 - Danish interface, dark map, no accounts and no ads
With Docker, which is the recommended way to run it on a server:
docker compose up -d --buildThen open http://localhost:5173. No API keys or accounts are needed: the server fetches everything from the open data sources itself. The first start takes about 30 seconds while it indexes the newest model run; after that, data is cached on disk (about 350 MB).
Useful settings: PORT and CACHE_DIR when running locally, and PREFETCH in
docker-compose.yml to control how much of each model run is prepared in advance.
For HTTPS and a domain, put a reverse proxy such as Caddy in front.
