Porvoo Ski is a ski area in Finland, at about 7 m. Its mapped area is about 0.5 km across, with 4 marked runs and 3 lifts (about 1.3 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 110 cm of snowfall a season, 2,236th (tied) of 3,069 worldwide and 27th in Finland. It swings a lot from year to year: the biggest winter, 2022/23 (190 cm), brought more than 4 times as much as the leanest, 2025/26 (45 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.
When it falls, and how winters differ
Month by month
Month by month, the most snow falls in January. March brings 47% of January’s snowfall. That is a steeper fall than the median for ski areas in Finland (80%): the snow here is concentrated early in the season. In amount, March brings 17 cm, less than the median of 23 cm.
Winter by winter
Across the 12 winters measured, the average is 110 cm, and 6 of them fell short of it. The leanest was 2025/26 with 45 cm; the biggest was 2022/23 with 190 cm (4.2 times as much). For 67% of the 52 ski areas in Finland, the leanest winter was the same 2025/26: 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.
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
100% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.
