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
Brévent/Flégère (Chamonix), in France, runs from 1,047 m at the base to 2,486 m at the top. Its mapped area is about 7.9 km across, with 65 marked runs and 18 lifts (about 41 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 432 cm of snowfall a season, 129th (tied) of 3,069 worldwide and 5th in France. It swings a lot from year to year: the biggest winter, 2017/18 (717 cm), brought more than twice as much as the leanest, 2016/17 (278 cm). March still brings 101 cm on average, close to January, its snowiest month.
The nearest city of any size is Geneva, about 63 km away in a straight line.
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.
The figures are for the whole of “Brévent/Flégère (Chamonix)”, which the map draws as one ski area.

55% 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.
The most snow falls in January. March brings 81% of January’s snowfall. That is in line with the median for ski areas in France (77%). In amount, March brings 101 cm, more than the median of 55 cm.

Winter by winter
Across the 12 winters measured, the average is 432 cm, and 6 of them fell short of it. The leanest was 2016/17 with 278 cm; the biggest was 2017/18 with 717 cm (2.6 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.
