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.

Score breakdown
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 Sima, in Canada, runs from 870 m at the base to 1,186 m at the top. Its mapped area is about 1.8 km across, with 17 marked runs and 3 lifts (about 9.9 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 83 cm of snowfall a season, 2,549th (tied) of 3,069 worldwide and 152nd in Canada. It swings a lot from year to year: the biggest winter, 2020/21 (138 cm), brought more than 3 times as much as the leanest, 2018/19 (43 cm). December brings as much snow as January here (26 and 25 cm on average).
Runs and lifts
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.

The shape of the mountain
Which way the slopes face
98% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

Live cameras
This ski area does not put a camera on its own slopes. What follows are nearby cameras, not the pistes themselves.
Footage remains the copyright of each operator. JAPANSNOWLINE neither stores nor redistributes it.
Some cameras here are provided by Windy.com. Footage plays in Windy’s own player; we do not store it. Windy.com
How much snow it gets
Measured by us across 3,069 ski areas by one identical method. These are not the resort’s own published figures.
Compared with what is nearby
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 |
|---|---|---|---|
| Whitehorse Nordic Centre | 11.0 km | 79 cm | 2595 |
| Mt. Lorne Ski Trails | 20.0 km | 94 cm | 2439 |
| Marsh Lake Ski Trails | 49.0 km | 76 cm | 2621 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in December. March brings 60% of January’s snowfall. That is a steeper fall than the median for ski areas in Canada (79%): the snow here is concentrated early in the season. In amount, March brings 15 cm, less than the median of 32 cm.
Winter by winter
Across the 12 winters measured, the average is 83 cm, and 6 of them fell short of it. The leanest was 2018/19 with 43 cm; the biggest was 2020/21 with 138 cm (3.2 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
