Estación Esquí Antillanca
Estación Esquí Antillanca is a ski area in Chile, at about 1,308 m. Its mapped area is about 3.4 km across, with 17 marked runs and 5 lifts (about 16 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 577 cm of snowfall a season, 48th of 3,069 worldwide and 3rd in Chile. It swings a lot from year to year: the biggest winter, 2017 (980 cm), brought more than 5 times as much as the leanest, 2016 (164 cm). Snowfall days average −1.0 °C at mid-mountain, close to freezing, so the snow is often heavy, and its snow-quality score ranks 8th of 11 in Chile.
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.

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.

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in August. September brings 76% of July’s snowfall. That is in line with the median for ski areas in Chile (77%). In amount, September brings 109 cm, more than the median of 54 cm.
Winter by winter
Across the 12 winters measured, the average is 577 cm, and 6 of them fell short of it. The leanest was 2016 with 164 cm; the biggest was 2017 with 980 cm (6.0 times as much). For 45% of the 11 ski areas in Chile, the leanest winter was the same 2016: bad winters tend to hit a whole region at once.

Guides covering Chile
- 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.
