Mont Lyall is a ski area in Canada, at about 514 m. Within 1.9 km of its centre the map shows 14 marked runs (about 6.2 km of piste).
Over the last twelve winters the ERA5 weather model gives it 228 cm of snowfall a season, 893rd (tied) of 3,069 worldwide and 20th in Canada. Its winters are fairly steady; even the leanest, 2014/15 (174 cm), reached 76% of the average. March is usually the snowiest month, with about 61 cm.
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.

Runs and lifts
Counted from the marked runs and lifts on the map, within 1.9 km of the centre of the ski area. These are not the resort’s own published figures.
By difficulty
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.
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 straight line. Measured the same way, so the ranks compare directly. Ski areas a few kilometres apart share a weather grid cell and can return the same figure.
| Ski area | Distance | Seasonal snowfall | World rank |

| Mont Vallières-de-Saint-Réal | 3.8 km | 228 cm | 893 |
| Cuve de l'Aigle | 22 km | 270 cm | 618 |
| Cuves de la Mine | 24 km | 270 cm | 618 |

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in March. March brings as much as January, or more. In amount, March brings 61 cm, more than the median of 32 cm.
Winter by winter
Across the 12 winters measured, the average is 228 cm, and 7 of them fell short of it. The leanest was 2014/15 with 174 cm; the biggest was 2021/22 with 296 cm (1.7 times as much). For 28% of the 171 ski areas in Canada, the leanest winter was the same 2014/15: bad winters tend to hit a whole region at once.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
