No snow yet. Snow depth and the seven-day outlook appear once snow is on the ground or forecast.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →
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.

Grenchenberg, in Switzerland, runs from 1,241 m at the base to 1,363 m at the top. Its mapped area is about 0.7 km across, with 2 marked runs and 2 lifts (about 0.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 83 cm of snowfall a season, 2,549th (tied) of 3,069 worldwide and 276th in Switzerland. It swings a lot from year to year: the biggest winter, 2020/21 (153 cm), brought more than 3 times as much as the leanest, 2024/25 (46 cm). January is usually the snowiest month, with about 28 cm.
Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.

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.
Only 0% of the vertical on the runs descends to the north or east. The most common direction is west (94%).

The most snow falls in January. March brings 46% of January’s snowfall. That is a steeper fall than the median for ski areas in Switzerland (76%): the snow here is concentrated early in the season. In amount, March brings 13 cm, less than the median of 60 cm.
Across the 12 winters measured, the average is 83 cm, and 7 of them fell short of it. The leanest was 2024/25 with 46 cm; the biggest was 2020/21 with 153 cm (3.3 times as much). For 47% of the 283 ski areas in Switzerland the leanest winter was 2016/17; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

In Japan, Height Barely Predicts Snowfall: +0.02, Against +0.58 in FranceAcross 3,069 ski areas we measure, height and snowfall move together — +0.58 in France, +0.85 in Germany. In Japan the figure is +0.02. The reason is not that elevation stopped working.
