Sewall Woods Conservation Area
Sewall Woods Conservation Area is a ski area in United States, at about 192 m. Its mapped area is about 1.8 km across.
Over the last twelve winters the ERA5 weather model gives it 129 cm of snowfall a season, 1,976th (tied) of 3,069 worldwide and 285th in the United States. It swings a lot from year to year: the biggest winter, 2022/23 (184 cm), brought more than twice as much as the leanest, 2015/16 (65 cm). January is usually the snowiest month, with about 36 cm.
Snow depth and the seven-day outlook appear here once snow starts to fall. Until then, the long-run record comes first.

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.

When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 78% of January’s snowfall. That is in line with the median for ski areas in the United States (85%). In amount, March brings 28 cm, about the same as the median of 30 cm.
Winter by winter
Across the 12 winters measured, the average is 129 cm, and 7 of them fell short of it. The leanest was 2015/16 with 65 cm; the biggest was 2022/23 with 184 cm (2.8 times as much). For 33% of the 534 ski areas in the United States, the leanest winter was the same 2015/16: bad winters tend to hit a whole region at once.
