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
Luz Ardiden, in France, runs from 1,690 m at the base to 2,485 m at the top. Its mapped area is about 3.7 km across, with 47 marked runs and 8 lifts (about 27 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 402 cm of snowfall a season, 170th (tied) of 3,069 worldwide and 19th in France. It swings a lot from year to year: the biggest winter, 2017/18 (695 cm), brought more than twice as much as the leanest, 2022/23 (253 cm). January is usually the snowiest month, with about 116 cm.
Runs and lifts
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.

89% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
The most snow falls in January. March brings 77% of January’s snowfall. That is in line with the median for ski areas in France (77%). In amount, March brings 89 cm, more than the median of 55 cm.

Winter by winter
Across the 12 winters measured, the average is 402 cm, and 7 of them fell short of it. The leanest was 2022/23 with 253 cm; the biggest was 2017/18 with 695 cm (2.7 times as much). For 26% of the 244 ski areas in France the leanest winter was 2016/17; here it was a different one.
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.
