Mountain data for Montenegro
64,288 daily readings of snow depth and temperature for 16 named places in Montenegro, 2015 to 2025, and 8 summit routes measured along the path network. Assembled here, and as far as we can tell not available as a file anywhere else.

Take it
- Snow and temperature by month (CSV)One row per subject per month: the share of days carrying snow, the mean depth, the mean daily high.
- Snow by winter (CSV)One row per subject per winter — the spread, which is the part an average hides.
- Summit routes (CSV)Distance, ascent, trailhead coordinate and start and finish height for each computed route.
- One row per subject (CSV)The atlas itself: elevation, massif, park area, difficulty, nearest official station.
- Map data (GeoJSON)Subjects as points and the routed paths as lines, ready to drop into a map.
- Everything, nested (JSON)Each subject with its monthly record, its winters and its route in one object.
What the file will not tell you, and why
Snow depths are published for 10 subjects and withheld for 5. The reanalysis does not correct snow depth for elevation the way it corrects temperature — the depth is the value for a grid cell about nine kilometres across. On the coastal ridges that cell is mostly low ground beside a warm sea, and it reports fifteen to twenty-four centimetres as an eleven-winter maximum at summits its own temperatures put at or below freezing. Both cannot be true.
Those subjects carry `snowVerdict: suppress` and their depth columns are empty in every download, not just on the page. The temperature columns are filled, because the temperature is sound. Two other subjects share a grid cell with a neighbour and say so in `sharesCellWith`: the depths on those rows are the same numbers twice, and a file that hid that would invite you to treat one as corroborating the other.
What the columns mean
| slug | Permanent identifier for the subject. These keys never change, so they are safe to join on. |
|---|---|
| deepPct | Share of days in that month carrying a base of 30 cm or more, across the archive. Empty where the depths are suppressed. |
| meanTmaxC | Mean daily maximum air temperature in °C, downscaled to this subject’s own elevation. Filled for every subject. |
| snowVerdict | publish, suppress or no-snow. The reason a depth column is empty. |
| demElevationM | Terrain height at the queried coordinate, from the Copernicus DEM. What the temperature is corrected to — not what the snow depth describes. |
| sharesCellWith | Other subjects in the same grid cell, and therefore with the same depth record. |
| routeDistanceM | One-way walking distance in metres from the nearest drivable point to the summit, along the OpenStreetMap path network. |
| routeAscentM | Total ascent in metres along that route, including the dips. A floor: a 90 m model smooths short steep steps. |
Where it comes from, and what you may do with it
The weather is ERA5-Land, the Copernicus reanalysis, served by Open-Meteo. The elevations, paths, park boundaries and summit coordinates are OpenStreetMap’s, under the ODbL. Park rules come from the national park authority. None of that is ours and all of it is named in the file’s own attribution header.
What is ours is the assembly, the routing, the hand-verified facts and the judgement about which depths are publishable — and that is published under CC BY 4.0. Use it, chart it, rebuild it, credit us, and credit Copernicus and OpenStreetMap for what is theirs.
Deliberately not included: the live station readings on the subject pages. Those are the national hydrometeorological institute’s measurements, they change daily, and mirroring somebody else’s observations in a download of ours is the one thing this atlas is careful not to do.
