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.

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 Rolle, in Italy, runs from 1,402 m at the base to 2,351 m at the top. Its mapped area is about 2.7 km across, with 64 marked runs and 22 lifts (about 43 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 211 cm of snowfall a season, 1,048th (tied) of 3,069 worldwide and 51st in Italy. It swings a lot from year to year: the biggest winter, 2020/21 (405 cm), brought more than 5 times as much as the leanest, 2021/22 (80 cm). December brings as much snow as January here (55 and 43 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.
The figures are for the whole of “San Martino di Castrozza - Passo Rolle”, which the map draws as one ski area.
56% 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.

| San Martino di Castrozza | 4.7 km | 204 cm | 1117 |
| Ski Area Alpe Lusia | 8.3 km | 175 cm | 1368 |

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.
