No snow yet. 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.

Cerro Bayo, in Argentina, runs from 1,045 m at the base to 1,779 m at the top. Its mapped area is about 3.0 km across, with 39 marked runs and 13 lifts (about 18 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 387 cm of snowfall a season, 197th of 3,069 worldwide and 6th in Argentina. It swings a lot from year to year: the biggest winter, 2020 (600 cm), brought more than 3 times as much as the leanest, 2025 (181 cm). Snowfall days average −0.4°C at mid-mountain, close to freezing, so the snow is often heavy, and its snow-quality score ranks 10th of 13 in Argentina.

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. The weather model works on cells about 30 km across; ski areas in the same cell get the same figure, and these numbers cannot separate them.
