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
Tromsø Alpinpark, in Norway, runs from 45 m at the base to 499 m at the top. Its mapped area is about 2.0 km across, with 9 marked runs and 3 lifts (about 5.5 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 270 cm of snowfall a season, 618th (tied) of 3,069 worldwide and 47th in Norway. It swings a lot from year to year: the biggest winter, 2019/20 (354 cm), brought more than twice as much as the leanest, 2017/18 (161 cm). March is usually the snowiest month, with about 78 cm.
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.

Which way the slopes face
91% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

When it falls, and how winters differ
Month by month
The most snow falls in March. March brings as much as January, or more. In amount, March brings 78 cm, more than the median of 47 cm.
Winter by winter
Across the 12 winters measured, the average is 270 cm, and 6 of them fell short of it. The leanest was 2017/18 with 161 cm; the biggest was 2019/20 with 354 cm (2.2 times as much). For 34% of the 135 ski areas in Norway the leanest winter was 2025/26; here it was a different one.
Snowfall each winter (December–March total). The dashed line is the average; the numbers mark the leanest and the biggest winter.
