No snow yet. Snow depth and the seven-day outlook appear once snow is on the ground or forecast.
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.

L'Alpe du Grand Serre, in France, runs from 1,363 m at the base to 2,166 m at the top. Its mapped area is about 5.3 km across, with 52 marked runs and 14 lifts (about 37 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 334 cm of snowfall a season, 330th (tied) of 3,069 worldwide and 55th in France. It swings a lot from year to year: the biggest winter, 2017/18 (640 cm), brought more than twice as much as the leanest, 2014/15 (220 cm). December brings as much snow as January here (93 and 92 cm on average).
The nearest city of any size is Grenoble, about 22 km away in a straight line.
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.

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.
75% 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 December. March brings 87% of January’s snowfall. That is a gentler fall than the median for ski areas in France (77%). In amount, March brings 80 cm, more than the median of 55 cm.
Across the 12 winters measured, the average is 334 cm, and 6 of them fell short of it. The leanest was 2014/15 with 220 cm; the biggest was 2017/18 with 640 cm (2.9 times as much). For 26% of the 244 ski areas in France the leanest winter was 2016/17; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

A Black Run in Colorado and a Black Run in Austria Are Not the Same Thing. The Maps Prove It.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.
