Trillevallen
Trillevallen is a ski area in Sweden, on slopes between roughly 894 and 894 m. Its mapped area is about 8.0 km across, with 45 marked runs and 9 lifts (about 16 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 146 cm of snowfall a season, 1,714th (tied) of 3,069 worldwide and 19th in Sweden. Its winters are fairly steady; even the leanest, 2025/26 (100 cm), reached 68% of the average. March still brings 38 cm on average, close to January, its snowiest month.
Elevation range is estimated by sampling points across the ski area.
We do not show a snow depth here. The weather model we use reports snow lying on the ground — it knows nothing about grooming or snowmaking, and it is not the base depth a ski area publishes. In Japan we can check our figures against 234 weather stations. Outside Japan there is nothing to check them against, so we do not print a number we have not verified.

Runs and lifts
Counted from the runs and lifts drawn on OpenStreetMap, within the boundary of the ski area. These are not the resort’s own published figures.

Which way the slopes face
84% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

How much snow it gets
Measured by us across 3,069 ski areas by one identical method. These are not the resort’s own published figures.
Compared with what is nearby
Within 50 km straight line. Measured the same way, so the ranks compare directly. Ski areas a few kilometres apart share a weather grid cell and can return the same figure.
