No snow yet. Snow depth and the seven-day outlook appear once snow is on the ground or forecast.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →

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.

O2 Resort, in South Korea, runs from 844 m at the base to 1,416 m at the top. Its mapped area is about 2.9 km across, with 6 marked runs and 3 lifts (about 10 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 66 cm of snowfall a season, 2,697th (tied) of 3,069 worldwide and 3rd in South Korea. It swings a lot from year to year: the biggest winter, 2017/18 (130 cm), brought more than 3 times as much as the leanest, 2021/22 (33 cm). March is usually the snowiest month, with about 24 cm.
How much snow it gets
Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
Compared with what is nearby
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.
| Ski area | Distance | Seasonal snowfall | World rank |

| HiOne Ski | 9.9 km | 64 cm | 2717 |
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.

Which way the slopes face
95% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

When it falls, and how winters differ
Month by month
The most snow falls in March. March brings as much as January, or more. In amount, March brings 24 cm, more than the median of 7 cm.
Winter by winter
Across the 12 winters measured, the average is 66 cm, and 7 of them fell short of it. The leanest was 2021/22 with 33 cm; the biggest was 2017/18 with 130 cm (3.9 times as much). For 40% of the 15 ski areas in South Korea the leanest winter was 2019/20; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
