Diavolezza-Lagalb is a ski area in Switzerland, at about 2,434 m. Its mapped area is about 8.8 km across, with 20 marked runs and 7 lifts (about 19 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 201 cm of snowfall a season, 1,140th (tied) of 3,069 worldwide and 208th in Switzerland. It swings a lot from year to year: the biggest winter, 2023/24 (333 cm), brought more than twice as much as the leanest, 2022/23 (124 cm). December brings as much snow as January here (58 and 50 cm on average).
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.

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
58% 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.

| Pontresina | 8.3 km | 197 cm | 1174 |
| St. Moritz | 13 km | 210 cm | 1057 |
| Corvatsch-Furtschellas | 13 km | 210 cm | 1057 |

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in December. March brings 98% of January’s snowfall. That is a gentler fall than the median for ski areas in Switzerland (76%). For skiing, though, the amount matters more than the share: March brings 49 cm, less than the median of 60 cm.
Winter by winter
Across the 12 winters measured, the average is 201 cm, and 8 of them fell short of it. The leanest was 2022/23 with 124 cm; the biggest was 2023/24 with 333 cm (2.7 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

Guides covering Switzerland
- Everywhere on Earth You Climb for Snow. Japan Is the One Place You Drive Toward the Sea. Across 3,069 ski areas we measure, height and snowfall move together — +0.58 in France, +0.85 in Germany. In Japan the figure is +0.02. The reason is not that elevation stopped working.
- 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 Much Does Snowfall Change From One Winter to the Next? Country by Country Over twelve winters, the typical Japanese ski area's best winter was 2.3 times its worst. In Italy and Chile it was 4.6 times, in New Zealand 4.2. Canada, Finland and Sweden come out steadier than Japan.
