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
Bardonecchia - Jafferau, in Italy, runs from 1,349 m at the base to 2,708 m at the top. Its mapped area is about 4.6 km across, with 28 marked runs and 5 lifts (about 20 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 283 cm of snowfall a season, 554th (tied) of 3,069 worldwide and 13th in Italy. It swings a lot from year to year: the biggest winter, 2017/18 (535 cm), brought more than twice as much as the leanest, 2021/22 (187 cm). December brings as much snow as January here (79 and 76 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.
Only 14% of the vertical on the runs descends to the north or east. The most common direction is west (78%).
Source: OpenSkiMap (© OpenStreetMap contributors, ODbL 1.0). How finely ski areas are drawn varies by region, so treat the counts as indicative. Vertical is the difference between the highest and lowest points of the mapped runs and lifts.
This ski area does not put a camera on its own slopes. What follows are nearby cameras, not the pistes themselves.

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 |
|---|---|---|---|
| Bardonecchia | 5.1 km | 250 cm | 734 |
| Valfréjus | 10.0 km | 333 cm | 333 |
| La Norma | 12.0 km | 318 cm | 408 |
| Sauze D'Oulx | 14.0 km | 231 cm | 865 |
| Sansicario | 15.0 km | 231 cm | 865 |
The most snow falls in December. March brings 96% of January’s snowfall. That is a steeper fall than the median for ski areas in Italy (116%): the snow here is concentrated early in the season. For skiing, though, the amount matters more than the share: March brings 73 cm, more than the median of 48 cm.
Across the 12 winters measured, the average is 283 cm, and 8 of them fell short of it. The leanest was 2021/22 with 187 cm; the biggest was 2017/18 with 535 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.
