Chiwawa Sno-Park
Chiwawa Sno-Park is a ski area in United States, on slopes between roughly 637 and 637 m. Its mapped area is about 5.2 km across.
Over the last twelve winters the ERA5 weather model gives it 262 cm of snowfall a season, 660th (tied) of 3,069 worldwide and 53rd in the United States. It swings a lot from year to year: the biggest winter, 2015/16 (450 cm), brought more than twice as much as the leanest, 2014/15 (190 cm). December brings as much snow as January here (96 and 77 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.
Elevation range is estimated by sampling points across the ski area.
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 |
|---|---|---|---|
| Leavenworth Ski Hill | 22 km | 263 cm | 657 |
| Icicle River Ski & Snowshoe Area | 29 km | 227 cm | 899 |
| Echo Valley Ski Area | 48 km | 143 cm | 1761 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in December. March brings 48% of January’s snowfall. That is a steeper fall than the median for ski areas in the United States (85%): the snow here is concentrated early in the season. For skiing, though, the amount matters more than the share: March brings 37 cm, more than the median of 30 cm.
Winter by winter
Across the 12 winters measured, the average is 262 cm, and 8 of them fell short of it. The leanest was 2014/15 with 190 cm; the biggest was 2015/16 with 450 cm (2.4 times as much). For 33% of the 534 ski areas in the United States, the leanest winter was the same 2014/15: bad winters tend to hit a whole region at once.
