Alyeska Resort
Alyeska Resort is a ski area in United States, at about 579 m. Its mapped area is about 4.2 km across, with 73 marked runs and 7 lifts (about 30 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 574 cm of snowfall a season, 50th (tied) of 3,069 worldwide and 6th in the United States. It swings a lot from year to year: the biggest winter, 2015/16 (1,116 cm), brought more than 3 times as much as the leanest, 2025/26 (318 cm). January is usually the snowiest month, with about 180 cm.
The nearest city of any size is Anchorage, about 52 km away.

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.

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 |
|---|---|---|---|
| Arctic Valley Ski Area | 39 km | 231 cm | 865 |
| Hilltop Ski Area | 41 km | 171 cm | 1407 |
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 58% 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. For skiing, though, the amount matters more than the share: March brings 104 cm, more than the median of 30 cm.
Winter by winter
Across the 12 winters measured, the average is 574 cm, and 8 of them fell short of it. The leanest was 2025/26 with 318 cm; the biggest was 2015/16 with 1,116 cm (3.5 times as much).
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
