Olos Ski Resort
Olos Ski Resort is a ski area in Finland, at about 386 m. Its mapped area is about 1.1 km across, with 31 marked runs and 5 lifts (about 6.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 103 cm of snowfall a season, 2,336th (tied) of 3,069 worldwide and 38th in Finland. It swings a lot from year to year: the biggest winter, 2019/20 (133 cm), brought more than twice as much as the leanest, 2017/18 (65 cm). December brings as much snow as January here (34 and 25 cm on average).
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.
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 December. March brings 88% of January’s snowfall. That is a gentler fall than the median for ski areas in Finland (80%). In amount, March brings 22 cm, about the same as the median of 23 cm.
Winter by winter
Across the 12 winters measured, the average is 103 cm, and 6 of them fell short of it. The leanest was 2017/18 with 65 cm; the biggest was 2019/20 with 133 cm (2.0 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
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 shape of the mountain
Which way the slopes face
97% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
