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.

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
Bivio, in Switzerland, runs from 1,767 m at the base to 2,542 m at the top. Its mapped area is about 4.3 km across, with 13 marked runs and 4 lifts (about 15 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 214 cm of snowfall a season, 1,008th (tied) of 3,069 worldwide and 186th in Switzerland. It swings a lot from year to year: the biggest winter, 2023/24 (346 cm), brought more than twice as much as the leanest, 2022/23 (128 cm). December brings as much snow as January here (56 and 55 cm on average).
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.
97% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

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.

The most snow falls in December. March brings as much as January, or more. In amount, March brings 55 cm, about the same as the median of 60 cm.
Across the 12 winters measured, the average is 214 cm, and 6 of them fell short of it. The leanest was 2022/23 with 128 cm; the biggest was 2023/24 with 346 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.
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.
