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.

The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
Cerro Castor, in Argentina, runs from 189 m at the base to 943 m at the top. Its mapped area is about 4.0 km across, with 40 marked runs and 11 lifts (about 29 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 147 cm of snowfall a season, 1,699th (tied) of 3,069 worldwide and 12th in Argentina. It swings a lot from year to year: the biggest winter, 2019 (203 cm), brought more than twice as much as the leanest, 2016 (85 cm). Snowfall days average −2.5°C at mid-mountain, and its snow-quality score ranks 11th of 13 in Argentina.
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.
Only 8% of the vertical on the runs descends to the north or east. The most common direction is south (65%).

Modelled from weather data the same way at all 3,069 ski areas we cover. 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 leaves out how much snow falls (it uses temperature, frequency, rain and wind).
The most snow falls in August. September brings 95% 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 35 cm, less than the median of 56 cm.
Across the 12 winters measured, the average is 147 cm, and 6 of them fell short of it. The leanest was 2016 with 85 cm; the biggest was 2019 with 203 cm (2.4 times as much).
Snowfall each winter (June–September total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
