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.

Bromley Mountain Ski Resort;Bromley Mountain, in United States, runs from 604 m at the base to 997 m at the top. Its mapped area is about 2.3 km across, with 67 marked runs and 8 lifts (about 23 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 155 cm of snowfall a season, 1,601st (tied) of 3,069 worldwide and 187th in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (228 cm), brought more than 4 times as much as the leanest, 2015/16 (46 cm). March still brings 36 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.
Only 31% of the vertical on the runs descends to the north or east. The most common direction is south (65%).

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.
