Las Leñas, in Mendoza, Argentina, runs from 2,240 m at the base to 3,430 m at the top. Within 2.5 km of its centre the map shows 13 marked runs and 9 lifts (about 14 km of piste).
Over the last twelve winters the ERA5 weather model gives it 469 cm of snowfall a season, 97th (tied) of 3,069 worldwide and 4th in Argentina. It swings a lot from year to year: the biggest winter, 2023 (1,034 cm), brought more than 5 times as much as the leanest, 2016 (196 cm). Snowfall days average −3.2 °C at mid-mountain, and its snow-quality score ranks 1st 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 marked runs and lifts on the map, within 2.5 km of the centre of the ski area. These are not the resort’s own published figures.

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 June. September brings 88% of July’s snowfall. That is a gentler fall than the median for ski areas in Argentina (61%). In amount, September brings 79 cm, more than the median of 56 cm.
Winter by winter
Across the 12 winters measured, the average is 469 cm, and 8 of them fell short of it. The leanest was 2016 with 196 cm; the biggest was 2023 with 1,034 cm (5.3 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.

What we have measured at Las Leñas
- Which Famous Ski Resorts Actually Get the Most Snow? 24 Names, Measured Niseko is 526th in the world for snowfall. Zermatt is 554th, Jackson Hole 924th, Aspen 1,201st. 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%.
- 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.
- Where to Ski in July and August: Argentina Has the Deepest Snow of Any Country on Earth, and Everyone Books New Zealand Argentina's median ski area gets 348 cm a season — more than Japan's 249 cm, and the highest median of any country we measure with ten or more ski areas. New Zealand's median is 144 cm. The English-language northern-summer ski trip points at the wrong hemisphere's end.
- Where Is the Driest Snow in the Southern Hemisphere? We extended our snow-quality measurement to all 59 ski areas below the equator. The high Andes are drier than most of Japan. New Zealand and Australia get rain on a third of winter days. And the southern hemisphere's snowiest resorts are mostly not its best ones.
