Urnäsch Osteregg is a ski area in Switzerland, at about 935 m. Its mapped area is about 1.3 km across, with 4 marked runs and 2 lifts (about 2.1 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 213 cm of snowfall a season, 1,022nd (tied) of 3,069 worldwide and 193rd in Switzerland. It swings a lot from year to year: the biggest winter, 2017/18 (324 cm), brought more than twice as much as the leanest, 2016/17 (131 cm). January is usually the snowiest month, with about 73 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.

| Gonten | 4.4 km | 213 cm | 1022 |
| Schwellbrunn | 6.1 km | 213 cm | 1022 |
| Hemberg | 8.6 km | 219 cm | 966 |

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 60% of January’s snowfall. That is a steeper fall than the median for ski areas in Switzerland (76%): the snow here is concentrated early in the season. In amount, March brings 44 cm, less than the median of 60 cm.
Winter by winter
Across the 12 winters measured, the average is 213 cm, and 7 of them fell short of it. The leanest was 2016/17 with 131 cm; the biggest was 2017/18 with 324 cm (2.5 times as much). For 47% of the 283 ski areas in Switzerland, 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.
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.

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.
