Valdelén is a ski area in Argentina, at about 667 m. Its mapped area is about 1.5 km across, with 11 marked runs and 4 lifts (about 4.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 123 cm of snowfall a season, 2,056th (tied) of 3,069 worldwide and 13th in Argentina. It swings a lot from year to year: the biggest winter, 2015 (210 cm), brought more than 5 times as much as the leanest, 2016 (42 cm). Snowfall days average −2.4 °C at mid-mountain, and its snow-quality score ranks 12th of 13 in Argentina.
Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.

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.
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.
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in August. September brings 87% of July’s snowfall. That is a gentler fall than the median for ski areas in Argentina (61%). For skiing, though, the amount matters more than the share: September brings 27 cm, less than the median of 56 cm.
Winter by winter
Across the 12 winters measured, the average is 123 cm, and 8 of them fell short of it. The leanest was 2016 with 42 cm; the biggest was 2015 with 210 cm (5.0 times as much). For 62% of the 13 ski areas in Argentina, the leanest winter was the same 2016: bad winters tend to hit a whole region at once.
Snowfall each winter (June–September 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
95% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

Measured identically across 3,069 ski areas, the names everyone books and the places it actually snows turn out to be two different lists.
- Nevados de Chillán: South America's Snowiest Ski Area, and Why Its Snow Is Wet Nevados de Chillán gets 752 cm a season, 3rd of the 3,069 ski areas we measure and the most in South America by a distance. Its snow falls at an average of +0.3 °C, which is the catch, and its winters run from 188 cm to 1,121 cm.
- 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%.
