Ylläs snow history

Ylläs averages 178cm of snowfall over a full season, measured from November to May across the last 10 winters. That is well below average: more snow than 21% of 39 resorts we have analysed the same way, where the median season brings 294cm.

Season to season the spread is wide. The best of the last 10 winters was 2019/20 with 213cm, and the leanest was 2025/26 with 152cm — a difference of 61cm between a good year and a poor one. The most recent complete season, 2025/26, delivered 152cm.

December is reliably the snowiest month, averaging 37cm and 12 days with fresh snow.

Snowfall totals flatter resorts that lose their snow quickly, so the more useful number is how deep the settled base actually gets. At Ylläs the snowpack peaks at an average of 85cm each season. That is about average, deeper than 54% of 39 resorts we have analysed the same way, against a median peak of 84cm.

The base is deepest in March, averaging 74cm through the month and topping out around 81cm in a typical year.

Counting any day that delivers at least 15cm of new snow, Ylläs averages 0 powder days a season. That is well below average, more powder days than fewer than every other resort in the set, where the median is 2 a season.

Powder days are not spread evenly. December averages 0.0 of them, which is the single strongest argument for timing a trip around the middle of the season rather than the edges.

A bluebird day means sunshine for at least 60% of daylight on the back of at least 10cm of snow in the previous 3 days — fresh snow and clear skies together, which is the combination people actually travel for. Ylläs averages 1 of them a season. That is well below average, more than 10% of 39 resorts we have analysed the same way, against a median of 10.

March is the best month for it, averaging 0.2 bluebird days and 6.3 hours of sunshine a day.

Rain is the thing that ruins a ski week, and at mid-mountain height Ylläs sees an average of 13 days a season with at least 1mm of rain rather than snow. That is well below average: 8% of the 39 other resorts we have analysed the same way see fewer wet days, against a median of 32.

May carries the most of it, with 7.3 rain days and 36mm in an average year. Bear in mind these figures are for the middle of the mountain: the base area will be wetter and the top drier.

Ylläs typically holds at least 30cm of settled snow from around 27 November through to 12 May, which works out at roughly 168 days of skiable cover in an average year. 166 of those fall inside the November to May season. On season length that is well above average compared with the 39 other resorts we have analysed the same way.

In practice that means the snow is usually gone, or going, by 12 May. Anyone booking late in the season should be looking at the highest terrain here rather than the base, and anyone booking early should expect the upper mountain to open before the valley runs do.

If you want the deepest base, go in March. If you want the best chance of fresh snow, go in December. If you want fresh snow and sunshine together, March gives the most bluebird days. Those rarely fall in the same month, so it is worth deciding which one matters most to you before you book.
