Chamonix-Mont-Blanc, in Haute-Savoie, France, runs from 1,035 m at the base to 3,842 m at the top. The map shows 65 marked runs and 18 lifts (about 41 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 338 cm of snowfall a season, 315th (tied) of 3,069 worldwide and 48th in France. It swings a lot from year to year: the biggest winter, 2017/18 (565 cm), brought more than twice as much as the leanest, 2016/17 (212 cm). January is usually the snowiest month, with about 104 cm.
The nearest city of any size is Geneva, about 65 km away. Below is a link to its official live camera.
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.

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.

The shape of the mountain
Which way the slopes face
55% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

How much snow it gets
Measured by us across 3,069 ski areas by one identical method. These are not the resort’s own published figures.
Compared with what is nearby
Within 50 km straight line. Measured the same way, so the ranks compare directly. Ski areas a few kilometres apart share a weather grid cell and can return the same figure.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Brévent/Flégère (Chamonix) | 2.9 km | 432 cm | 129 |
| Aiguille du Midi (Chamonix) | 4.6 km | 486 cm | 87 |
| Le Tourchet (Chamonix) | 6.3 km | 365 cm | 239 |
| Les Chosalets (Chamonix) | 7.0 km | 327 cm | 370 |
| Les Grands Montets | 7.4 km | 421 cm | 147 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 75% of January’s snowfall. That is in line with the median for ski areas in France (77%). In amount, March brings 78 cm, more than the median of 55 cm.
Winter by winter
Across the 12 winters measured, the average is 338 cm, and 6 of them fell short of it. The leanest was 2016/17 with 212 cm; the biggest was 2017/18 with 565 cm (2.7 times as much). For 26% of the 244 ski areas in France, the leanest winter was the same 2016/17: bad winters tend to hit a whole region at once.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

Guides covering France
- 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.
- How Big Are Japan's Ski Areas? Smaller Than the Alps, Snowier per Kilometre Measured across nearly 1,800 ski areas: the median Japanese one has 12 km of piste against France's 25. What Japan has instead is 25 cm of seasonal snow for every kilometre of run — more than two and a half times France and three times the United States.
