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.

Les Mosses, in Switzerland, runs from 1,379 m at the base to 1,871 m at the top. Its mapped area is about 5.9 km across, with 39 marked runs and 14 lifts (about 26 km of piste in all).

Over the last twelve winters the ERA5 weather model gives it 284 cm of snowfall a season, 549th (tied) of 3,069 worldwide and 108th in Switzerland. It swings a lot from year to year: the biggest winter, 2017/18 (473 cm), brought more than twice as much as the leanest, 2014/15 (204 cm). January is usually the snowiest month, with about 85 cm.

How much snow it gets

69% of the vertical on the runs descends to the north or east; plenty of the terrain faces the sun as well, so the lean is modest.
