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.Snow report on the official site ↗

The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
Diavolezza-Lagalb, in Switzerland, runs from 2,084 m at the base to 3,003 m at the top. Its mapped area is about 8.8 km across, with 20 marked runs and 7 lifts (about 19 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 201 cm of snowfall a season, 1,140th (tied) of 3,069 worldwide and 208th in Switzerland. It swings a lot from year to year: the biggest winter, 2023/24 (333 cm), brought more than twice as much as the leanest, 2022/23 (124 cm). December brings as much snow as January here (58 and 50 cm on average).
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.

58% 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.
The most snow falls in December. March brings 98% of January’s snowfall. That is a gentler fall than the median for ski areas in Switzerland (76%). For skiing, though, the amount matters more than the share: March brings 49 cm, less than the median of 60 cm.

Average snowfall by month, last 12 winters
Winter by winter
Across the 12 winters measured, the average is 201 cm, and 8 of them fell short of it. The leanest was 2022/23 with 124 cm; the biggest was 2023/24 with 333 cm (2.7 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.
