Sarn-Heinzenberg is a ski area in Switzerland, at about 1,704 m. Its mapped area is about 3.8 km across, with 11 marked runs and 2 lifts (about 16 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 245 cm of snowfall a season, 765th (tied) of 3,069 worldwide and 152nd in Switzerland. It swings a lot from year to year: the biggest winter, 2023/24 (379 cm), brought more than twice as much as the leanest, 2022/23 (171 cm). March still brings 64 cm on average, close to January, its snowiest month.

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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Tschappina | 3.3 km | 235 cm | 823 |
| Tenna | 4.6 km | 228 cm | 893 |
| Feldis | 9.5 km | 232 cm | 853 |
| Obermutten | 9.8 km | 245 cm | 765 |
| Chur - Brambrüesch | 14 km | 217 cm | 978 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 97% of January’s snowfall. That is a gentler fall than the median for ski areas in Switzerland (76%). In amount, March brings 64 cm, about the same as the median of 60 cm.
Winter by winter
Across the 12 winters measured, the average is 245 cm, and 8 of them fell short of it. The leanest was 2022/23 with 171 cm; the biggest was 2023/24 with 379 cm (2.2 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
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 shape of the mountain
Which way the slopes face
69% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

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.
