Colle di Joux
Colle di Joux is a ski area in Italy, at about 1,723 m. Its mapped area is about 1.9 km across, with 6 marked runs and 2 lifts (about 3.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 223 cm of snowfall a season, 926th (tied) of 3,069 worldwide and 44th in Italy. It swings a lot from year to year: the biggest winter, 2017/18 (440 cm), brought more than 4 times as much as the leanest, 2021/22 (104 cm). March is usually the snowiest month, with about 72 cm.
Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.
Elevation of the ski area’s centre point, taken from a digital elevation model. It is not the base-to-summit range.
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.
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.

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in March. March brings as much as January, or more. In amount, March brings 72 cm, more than the median of 48 cm.
Winter by winter
Across the 12 winters measured, the average is 223 cm, and 8 of them fell short of it. The leanest was 2021/22 with 104 cm; the biggest was 2017/18 with 440 cm (4.2 times as much). For 55% of the 177 ski areas in Italy, the leanest winter was the same 2021/22: bad winters tend to hit a whole region at once.
