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.

Ancelle, in France, runs from 1,323 m at the base to 1,798 m at the top. Its mapped area is about 3.5 km across, with 56 marked runs and 14 lifts (about 23 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 145 cm of snowfall a season, 1,729th (tied) of 3,069 worldwide and 197th in France. It swings a lot from year to year: the biggest winter, 2017/18 (303 cm), brought more than 3 times as much as the leanest, 2018/19 (89 cm). December brings as much snow as January here (41 and 36 cm on average).
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.
73% 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 as much as January, or more. In amount, March brings 37 cm, less than the median of 55 cm.
Across the 12 winters measured, the average is 145 cm, and 7 of them fell short of it. The leanest was 2018/19 with 89 cm; the biggest was 2017/18 with 303 cm (3.4 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.
