Jisan Forest Ski Resort is a ski area in South Korea, at about 198 m. Its mapped area is about 1.3 km across, with 9 marked runs and 5 lifts (about 4.8 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 21 cm of snowfall a season, 2,973rd (tied) of 3,069 worldwide and 13th in South Korea. It swings a lot from year to year: the biggest winter, 2023/24 (39 cm), brought more than 3 times as much as the leanest, 2019/20 (11 cm). December brings as much snow as January here (5 and 5 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.
| Ski area | Distance | Seasonal snowfall | World rank |
|---|---|---|---|
| Yangji Pine Ski Resort | 4.0 km | 21 cm | 2973 |
| Konjiam Resort | 14 km | 21 cm | 2973 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in December. March brings as much as January, or more. In amount, March brings 5 cm, less than the median of 7 cm.
Winter by winter
Across the 12 winters measured, the average is 21 cm, and 8 of them fell short of it. The leanest was 2019/20 with 11 cm; the biggest was 2023/24 with 39 cm (3.5 times as much). For 40% of the 15 ski areas in South Korea, the leanest winter was the same 2019/20: bad winters tend to hit a whole region at once.

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
98% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
