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.Snow report on the official site ↗
Jaun, in Switzerland, runs from 1,021 m at the base to 1,570 m at the top. Its mapped area is about 2.6 km across, with 25 marked runs and 4 lifts (about 13 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 255 cm of snowfall a season, 692nd (tied) of 3,069 worldwide and 141st in Switzerland. It swings a lot from year to year: the biggest winter, 2017/18 (382 cm), brought more than twice as much as the leanest, 2024/25 (167 cm). January is usually the snowiest month, with about 81 cm.
How much snow it gets
Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.

Compared with what is nearby
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.
The most snow falls in January. March brings 67% 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 54 cm, about the same as the median of 60 cm.

Winter by winter
Across the 12 winters measured, the average is 255 cm, and 6 of them fell short of it. The leanest was 2024/25 with 167 cm; the biggest was 2017/18 with 382 cm (2.3 times as much). For 47% of the 283 ski areas in Switzerland the leanest winter was 2016/17; here it was a different one.
Across 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.
