No snow yet. Snow depth and the seven-day outlook appear once snow is on the ground or forecast.
A weather-model figure, worked out the same way for every ski area, and lower than what actually falls. Use it to compare ski areas, not against the resort’s own totals. How we measure →
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.
Mount Mawson, in Australia, runs from 1,220 m at the base to 1,245 m at the top. Its mapped area is about 1.6 km across, with 1 marked run and 3 lifts (about 0.2 km of piste in all).
Over the last twelve winters the ERA5 weather model gives it 68 cm of snowfall a season, 2,677th (tied) of 3,069 worldwide and 8th in Australia. It swings a lot from year to year: the biggest winter, 2017 (129 cm), brought more than 3 times as much as the leanest, 2016 (35 cm). Snowfall days average −0.9°C at mid-mountain, close to freezing, so the snow is often heavy, and its snow-quality score ranks 9th of 10 in Australia.
Modelled from weather data the same way at all 3,069 ski areas we cover. These are not the resort’s own published figures.
The tick marks the median across every Japanese ski area we measure. All four bars run the same way — longer is better.
The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).
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.
100% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

The most snow falls in August. September brings as much as July, or more. In amount, September brings 20 cm, about the same as the median of 23 cm.
Across the 12 winters measured, the average is 68 cm, and 7 of them fell short of it. The leanest was 2016 with 35 cm; the biggest was 2017 with 129 cm (3.7 times as much). For 70% of the 10 ski areas in Australia the leanest winter was 2015; here it was a different one.
Snowfall each winter (June–September total). The dashed line is the average; the numbers mark the leanest and the biggest winter.

Australia's Worst Ski Season in 20 Years: How Japan's Snow ComparesSnow depth at Spencers Creek peaked at 94.5 cm, the third lowest since 1954, and resorts closed in August. Our own measure — snowfall, not depth — puts Australia at 50% of its 12-year average. The gap between those two numbers is the story: it was the warmth, not only the lack of snow. New Zealand, meanwhile, finished at 108% of normal.
