Ski con amigos en Cerro Bayo.
By: Cerro Bayo Ski Boutique · 2016-07-28
Cerro Bayo is a ski area in Argentina, at about 1,382 m. 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.
Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.

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.

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.
