Ski Portillo, in Valparaíso, Chile, runs from 2,590 m at the base to 3,310 m at the top. The map shows 27 marked runs and 14 lifts (about 15 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 326 cm of snowfall a season, 378th (tied) of 3,069 worldwide and 6th in Chile. It swings a lot from year to year: the biggest winter, 2026 (642 cm), brought more than 5 times as much as the leanest, 2019 (123 cm). Snowfall days average −3.4 °C at mid-mountain, and its snow-quality score ranks 1st of 11 in Chile.

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.

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 |
|---|---|---|---|
| Los Puquios | 22 km | 314 cm | 430 |
| Los Penitentes | 27 km | 300 cm | 482 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in June. September brings 87% of July’s snowfall. That is a gentler fall than the median for ski areas in Chile (77%). In amount, September brings 54 cm, about the same as the median of 54 cm.
Winter by winter
Across the 12 winters measured, the average is 326 cm, and 8 of them fell short of it. The leanest was 2019 with 123 cm; the biggest was 2026 with 642 cm (5.2 times as much). For 55% of the 11 ski areas in Chile, the leanest winter was the same 2019: 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 Ski Portillo
- 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.
- Skiing From Santiago: Ski Areas Within 40 km, and Almost No Rain Only three cities of three million or more have a 300 cm ski area within 120 km: Santiago, Seattle and Nagoya. Santiago's nearest is 38 km, about half Seattle's distance — and the fields beside it see rain on 3% of winter days against a Japanese median of 16%.
- 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.
