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
Passo Stelvio, in Italy, runs from 2,769 m at the base to 3,355 m at the top. Its mapped area is about 4.6 km across, with 35 marked runs and 8 lifts (about 17 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 173 cm of snowfall a season, 1,389th (tied) of 3,069 worldwide and 100th in Italy. It swings a lot from year to year: the biggest winter, 2023/24 (301 cm), brought more than twice as much as the leanest, 2021/22 (104 cm). December brings as much snow as January here (50 and 41 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.
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.

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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Trafoi | 6.5 km | 160 cm | 1541 |
| Bormio Ski | 9.5 km | 177 cm | 1348 |
| Sulden am Ortler - Solda al Ortles | 10.0 km | 159 cm | 1553 |
| Cima Piazzi – San Colombano | 12.0 km | 227 cm | 899 |
| Santa Caterina | 13.0 km | 179 cm | 1330 |
The most snow falls in December. March brings as much as January, or more. In amount, March brings 43 cm, about the same as the median of 48 cm.
Across the 12 winters measured, the average is 173 cm, and 8 of them fell short of it. The leanest was 2021/22 with 104 cm; the biggest was 2023/24 with 301 cm (2.9 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

How Much Does Snowfall Change From One Winter to the Next? Country by CountryOver twelve winters, the typical Japanese ski area's best winter was 2.3 times its worst. In Italy and Chile it was 4.6 times, in New Zealand 4.2. Canada, Finland and Sweden come out steadier than Japan.
