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.

The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
Wisp Resort, in United States, runs from 751 m at the base to 944 m at the top. Its mapped area is about 3.4 km across, with 36 marked runs and 12 lifts (about 16 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 106 cm of snowfall a season, 2,301st (tied) of 3,069 worldwide and 353rd in the United States. It swings a lot from year to year: the biggest winter, 2020/21 (152 cm), brought more than twice as much as the leanest, 2022/23 (69 cm). January is usually the snowiest month, with about 40 cm.
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.
69% of the vertical on the runs descends to the north or east; plenty of the terrain faces the sun as well, so the lean is modest.

Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
Within 50 km in a straight line. Ski areas in the same weather-model cell (about 30 km across) get the same figure.

The most snow falls in January. March brings 50% 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. In amount, March brings 20 cm, less than the median of 30 cm.
Across the 12 winters measured, the average is 106 cm, and 8 of them fell short of it. The leanest was 2022/23 with 69 cm; the biggest was 2020/21 with 152 cm (2.2 times as much). For 33% of the 534 ski areas in the United States the leanest winter was 2015/16; 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.
