Cerro Catedral, in Río Negro, Argentina, runs from 1,030 m at the base to 2,180 m at the top. The map shows 96 marked runs and 33 lifts (about 57 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 348 cm of snowfall a season, 287th (tied) of 3,069 worldwide and 7th in Argentina. It swings a lot from year to year: the biggest winter, 2022 (510 cm), brought more than 3 times as much as the leanest, 2025 (160 cm). Snowfall days average −1.2 °C at mid-mountain, close to freezing, so the snow is often heavy, and its snow-quality score ranks 8th of 13 in Argentina.
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
85% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

Live Cameras
This ski area does not put a camera on its own slopes. What follows are nearby cameras, not the pistes themselves.
Footage remains the copyright of each operator. JAPANSNOWLINE neither stores nor redistributes it.
Some cameras here are provided by Windy.com. Footage plays in Windy’s own player; we do not store it. Windy.com
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.
The tick marks the median across every Japanese ski area we measure. All four bars run the same way — longer is better.
The quality score deliberately excludes how much snow falls — it uses temperature, frequency, rain and wind. Snowing a lot and snowing well are different things.
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 |
|---|---|---|---|
| Cerro Bayo | 49 km | 387 cm | 197 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in July. September brings 50% of July’s snowfall. That is a steeper fall than the median for ski areas in Argentina (61%): the snow here is concentrated early in the season. In amount, September brings 56 cm, about the same as the median of 56 cm.
Winter by winter
Across the 12 winters measured, the average is 348 cm, and 6 of them fell short of it. The leanest was 2025 with 160 cm; the biggest was 2022 with 510 cm (3.2 times as much).
Snowfall each winter (June–September total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

What we have measured at Cerro Catedral
- In the Andes, Height Does Not Buy You More Snow. It Buys You Snow Instead of Rain. In South America the low ski areas get more snow than the high ones — 387 cm against 307 cm in the middle of each group. Then look at the rain: 2% of winter days against 30%. Volcán Osorno sees rain on 65%. Los Penitentes sees it on 1%.
- What Is the Best Month to Ski the Andes? We counted every month of the last twelve southern winters at five Andes ski areas. The biggest month changes from year to year, and in 4 of 12 winters Valle Nevado got less than 20 cm in July. Hakuba's worst January over the same years was 97 cm.
- How Much Does Snow in Chile and Argentina Change From Winter to Winter? Three of the world's thirty snowiest ski areas are in South America on our standard measure. Over twelve winters, the typical Chilean ski area's best winter was about four and a half times its worst and the typical Argentine one's three and a half — against 2.3 in Japan. Only Italy swings as hard as Chile.
