Niseko or Las Leñas: Which Gets More Snow, and Which Gets Better Snow?

We measure snowfall and snow quality the same way at every ski area on this site. Here are the two names at the top of their hemispheres, side by side, on our standard figures.

	Las Leñas 🇦🇷	Niseko Grand Hirafu 🇯🇵
Snowfall, twelve-winter average	469 cm	289 cm
World rank, snowfall	=97	=526
Rain days	1%	7%
Days over 5 cm	22%	17%
Temperature when snowing	−3.2 °C	−6.2 °C
Wind when snowing	11 km/h	14 km/h
Quality score	22.1	23.3

Las Leñas gets more snow, rains a seventh as often, and delivers a 5 cm day more frequently. It still loses the quality score, narrowly, because Niseko’s snow falls three degrees colder.

Twelve winters, one at a time

An average flatters Las Leñas: one of its winters was enormous. So here is every winter of the last twelve at each.

	Worst	Typical	Average	Best
Las Leñas	196 cm	390 cm	469 cm	1,034 cm
Niseko	166 cm	296 cm	289 cm	384 cm

“Typical” is the median winter.

Las Leñas’s worst winter of the twelve was deeper than Niseko’s worst. In ten of the twelve it beat Niseko’s average winter, and it never once fell below Niseko’s worst.

That removes the argument this article used to make. Las Leñas does swing far more — its best winter was about five times its worst, against a little over twice for Niseko, but it swings above a higher floor. The risk with Las Leñas is not a thin year. It is that the average promises a winter it delivers rarely: its 1,034 cm season came once in twelve, and 2026 brought 808 cm. Without the 1,034 the average is 417 cm, and the middle winter is 390.

What Niseko actually has

Colder snow. Niseko’s snow falls at −6.2 °C against Las Leñas’s −3.2 °C, and three degrees is the difference between snow you float through and snow that sets up. That is why Niseko edges the quality score despite losing most of the other columns. It is a real advantage and it is the one to book for.

A usable calendar. Las Leñas’s season runs from late June to late September; Niseko’s from late November to early May. For most people these are not alternatives but two different holidays.

Towns, transport and English. Niseko has an infrastructure for overseas visitors that a single, remote resort in the south of Mendoza province does not. That is not a snow argument, and it does not need to be.

And Japan is not one thing:

	Snowfall	Rain days	Quality rank in Japan
Niseko	289 cm	7%	38
Hakuba Happo-One	414 cm	22%	102
Las Leñas	469 cm	1%	— (1st in Argentina)

Hakuba gets more snow than Niseko and rain on three times as many days. Hakuba is on Honshu, lower and further south, and the rain figure is why Japanese powder skiers talk about Hokkaido the way they do.

Which to book

For the most snow, Las Leñas — in a bad year as well as a good one, on this record. Its floor is higher than Niseko’s and its ceiling is in a different league.

For the lightest snow, Niseko. Three degrees colder is the whole of its case, and it is a good one.

If your dates are fixed months ahead, neither is a guarantee. Niseko’s worst winter of the twelve was 166 cm, and 2015/16 was a bad year right across Japan at once. For a trip you cannot move, the deepest Japanese valleys — Hakuba, Nozawa, the Niigata snowbelt — kept far more snow in their worst years than either of these.

And in the Andes, do not pick a fixed week expecting it to snow that week. The month-to-month record there is erratic even at places with deep seasons.

How this was measured

The first table uses our twelve-winter averages from the ERA5 reanalysis, computed identically for all 3,069 ski areas; ranks are world ranks among those 3,069. The twelve-winter table sums daily snowfall over each of the twelve most recent winters — June to September 2015–2026 for Las Leñas, December to March 2014/15–2025/26 for Niseko — on Japanese calendar days, the same boundary the rest of the site uses.

For what a typical season looks like, read the median (390 cm) rather than the average (469 cm): one enormous winter pulls the average up.

The model understates mountain snowfall — checked against 63 Japanese ground stations it returns about 56% of what they record, and more than that in Hokkaido, where the cold dry snow piles deeper than the model’s fixed conversion allows. That bias works in Niseko’s favour here: its true snowfall is likely higher than shown, and a like-for-like station comparison might narrow the gap. We have no equivalent ground check for the Andes.

The quality score multiplies four measured components: temperature on snow days, how often 5 cm or more falls, how often it rains instead, and wind on snow days. The weightings are our judgement, not a result, so a 1.2-point gap should be read as “these are close”. The full method is here.

Temperature is corrected for elevation using the standard 6.5 °C/km lapse rate. Niseko’s correction is 0.1 °C; Las Leñas’s is 2.1 °C, because it sits 320 m above the elevation its grid cell reports, so its temperature figure carries more model in it than Niseko’s does.

Revision history

• 13 September 2026. Rewritten on twelve winters. The three-winter version called Niseko the safer booking; over twelve winters Las Leñas’s worst winter (196 cm) was deeper than Niseko’s (166 cm).
