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
La Rosière, in France, runs from 1,192 m at the base to 2,799 m at the top. Its mapped area is about 11 km across, with 119 marked runs and 29 lifts (about 68 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 446 cm of snowfall a season, 114th (tied) of 3,069 worldwide and 3rd in France. It swings a lot from year to year: the biggest winter, 2017/18 (809 cm), brought more than twice as much as the leanest, 2016/17 (290 cm). January is usually the snowiest month, with about 135 cm.
The nearest city of any size is Geneva, about 83 km away in a straight line.

Only 18% of the vertical on the runs descends to the north or east. The most common direction is south (60%).
The most snow falls in January. March brings 76% of January’s snowfall. That is in line with the median for ski areas in France (77%). In amount, March brings 103 cm, more than the median of 55 cm.

Winter by winter
Across the 12 winters measured, the average is 446 cm, and 7 of them fell short of it. The leanest was 2016/17 with 290 cm; the biggest was 2017/18 with 809 cm (2.8 times as much).
Across 2,888 ski areas: 39% of American runs are graded advanced or harder, and 9% of Austrian ones. Nobody thinks Austria is four times gentler. The grades are measuring different things.
