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
Hermon Mountain, in United States, runs from 55 m at the base to 137 m at the top. Its mapped area is about 0.8 km across, with 16 marked runs and 2 lifts (about 3.3 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 126 cm of snowfall a season, 2,018th (tied) of 3,069 worldwide and 296th in the United States. Its winters are fairly steady; even the leanest, 2020/21 (100 cm), reached 79% of the average. January is usually the snowiest month, with about 37 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.
100% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
The most snow falls in January. March brings 73% 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 27 cm, about the same as the median of 30 cm.
Across the 12 winters measured, the average is 126 cm, and 6 of them fell short of it. The leanest was 2020/21 with 100 cm; the biggest was 2014/15 with 163 cm (1.6 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.
