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.
Rossberg - Oberwil, in Switzerland, runs from 1,148 m at the base to 1,467 m at the top. Its mapped area is about 1.6 km across, with 3 marked runs and 1 lift (about 3.3 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 210 cm of snowfall a season, 1,057th (tied) of 3,069 worldwide and 198th in Switzerland. It swings a lot from year to year: the biggest winter, 2017/18 (294 cm), brought more than twice as much as the leanest, 2016/17 (138 cm). January is usually the snowiest month, with about 63 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.
99% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

The most snow falls in January. March brings 76% of January’s snowfall. That is in line with the median for ski areas in Switzerland (76%). In amount, March brings 48 cm, less than the median of 60 cm.
Across the 12 winters measured, the average is 210 cm, and 7 of them fell short of it. The leanest was 2016/17 with 138 cm; the biggest was 2017/18 with 294 cm (2.1 times as much).
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.
