Estación Invernal de Astún
Estación Invernal de Astún is a ski area in Spain, at about 1,926 m. Its mapped area is about 4.1 km across, with 66 marked runs and 16 lifts (about 34 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 358 cm of snowfall a season, 262nd (tied) of 3,069 worldwide and 3rd in Spain. It swings a lot from year to year: the biggest winter, 2017/18 (579 cm), brought more than twice as much as the leanest, 2022/23 (230 cm). January is usually the snowiest month, with about 104 cm.
The nearest city of any size is Pamplona, about 94 km away.

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.
The figures are for the whole of “Astun”, which the map draws as one ski area.

Which way the slopes face
52% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

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.
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 January. March brings 79% of January’s snowfall. That is a steeper fall than the median for ski areas in Spain (102%): the snow here is concentrated early in the season. For skiing, though, the amount matters more than the share: March brings 82 cm, more than the median of 52 cm.
Winter by winter
Across the 12 winters measured, the average is 358 cm, and 6 of them fell short of it. The leanest was 2022/23 with 230 cm; the biggest was 2017/18 with 579 cm (2.5 times as much). For 29% of the 34 ski areas in Spain, the leanest winter was the same 2022/23: bad winters tend to hit a whole region at once.
