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.

La Sambuy Seythenex, in France, runs from 1,154 m at the base to 1,174 m at the top. Its mapped area is about 2.3 km across, with 1 marked run (about 0.2 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 204 cm of snowfall a season, 1,117th (tied) of 3,069 worldwide and 147th in France. It swings a lot from year to year: the biggest winter, 2017/18 (335 cm), brought more than 3 times as much as the leanest, 2016/17 (108 cm). January is usually the snowiest month, with about 66 cm.
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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Montmin - Col de la Forclaz | 11.0 km | 205 cm | 1105 |
| Le Semnoz | 17.0 km | 192 cm | 1230 |
| Aillon-le-Jeune | 18.0 km | 214 cm | 1008 |

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.
Only 0% of the vertical on the runs descends to the north or east. The most common direction is west (100%).

The most snow falls in January. March brings 61% of January’s snowfall. That is a steeper fall than the median for ski areas in France (77%): the snow here is concentrated early in the season. In amount, March brings 40 cm, less than the median of 55 cm.
Across the 12 winters measured, the average is 204 cm, and 5 of them fell short of it. The leanest was 2016/17 with 108 cm; the biggest was 2017/18 with 335 cm (3.1 times as much).
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.
