No snow yet. Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.

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.

Col de Porte, in France, runs from 1,226 m at the base to 1,327 m at the top. Its mapped area is about 2.5 km across, with 3 marked runs and 5 lifts (about 0.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 117 cm of snowfall a season, 2,129th (tied) of 3,069 worldwide and 224th in France. It swings a lot from year to year: the biggest winter, 2014/15 (192 cm), brought more than 3 times as much as the leanest, 2016/17 (56 cm). January is usually the snowiest month, with about 41 cm.

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. The weather model works on cells about 30 km across; ski areas in the same cell get the same figure, and these numbers cannot separate them.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Les Egaux - St Hugues | 3.5 km | 147 cm | 1699 |
| Sappey-en-Chartreuse | 4.5 km | 198 cm | 1164 |
| Saint-Pierre-de-Chartreuse | 8.8 km | 189 cm | 1248 |
| Saint-Hilaire-du-Touvet | 9.0 km | 199 cm | 1158 |
| Col de Marcieu | 12.0 km | 199 cm | 1158 |
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.

Which way the slopes face
95% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 51% 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 21 cm, less than the median of 55 cm.
Winter by winter
Across the 12 winters measured, the average is 117 cm, and 7 of them fell short of it. The leanest was 2016/17 with 56 cm; the biggest was 2014/15 with 192 cm (3.4 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.

- 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.
