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 →

Elevation of the ski area’s centre point, taken from a digital elevation model. It is not the base-to-summit range.
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
Mount Ashwabay Ski & Recreation Area is a ski area in United States, at about 331 m. Within 2.5 km of its centre the map shows 12 marked runs and 2 lifts (about 2.9 km of piste).
Over the last twelve winters the ERA5 weather model gives it 110 cm of snowfall a season, 2,236th (tied) of 3,069 worldwide and 343rd in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (193 cm), brought more than 3 times as much as the leanest, 2014/15 (56 cm). December brings as much snow as January here (35 and 24 cm on average).
Counted from the marked runs and lifts on the map, within 2.5 km of the centre of the ski area. These are not the resort’s own published figures.
Source: OpenStreetMap (ODbL 1.0). How finely ski areas are drawn varies by region, so treat the counts as indicative. Difficulty uses the European grades, which do not map onto North American green / blue / black.
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.
| Ski area | Distance | Seasonal snowfall | World rank |

The most snow falls in December. March brings as much as January, or more. In amount, March brings 26 cm, about the same as the median of 30 cm.
Across the 12 winters measured, the average is 110 cm, and 6 of them fell short of it. The leanest was 2014/15 with 56 cm; the biggest was 2022/23 with 193 cm (3.4 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.
