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
Dartmouth Skiway, in United States, runs from 280 m at the base to 580 m at the top. Its mapped area is about 2.3 km across, with 48 marked runs and 4 lifts (about 16 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 127 cm of snowfall a season, 2,001st (tied) of 3,069 worldwide and 288th in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (161 cm), brought more than twice as much as the leanest, 2015/16 (59 cm). March still brings 28 cm on average, close to January, its snowiest month.
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.
65% 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 80% of January’s snowfall.
Across the 12 winters measured, the average is 127 cm, and 4 of them fell short of it. The leanest was 2015/16 with 59 cm; the biggest was 2022/23 with 161 cm (2.7 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
