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 Greylock Ski Club is a ski area in United States, at about 437 m. Its mapped area is about 1.1 km across.
Over the last twelve winters the ERA5 weather model gives it 129 cm of snowfall a season, 1,976th (tied) of 3,069 worldwide and 282nd in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (184 cm), brought more than 5 times as much as the leanest, 2015/16 (36 cm). March still brings 30 cm on average, close to January, its snowiest month.
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 |
|---|---|---|---|
| Jiminy Peak Resort | 11.0 km | 121 cm | 2077 |
| Notchview | 20.0 km | 131 cm | 1942 |
| Bousquet Mountain | 25.0 km | 116 cm | 2148 |
| Berkshire East Ski Resort | 28.0 km | 134 cm | 1892 |
| Prospect Mountain | 29.0 km | 159 cm | 1553 |
