Adelboden snow history

Adelboden averages 565cm of snowfall over a full season, measured from November to May across the last 10 winters. That is among the very best we track: more snow than 95% of 40 resorts we have analysed the same way, where the median season brings 283cm.

Season to season the spread is wide. The best of the last 10 winters was 2023/24 with 794cm, and the leanest was 2025/26 with 450cm — a difference of 344cm between a good year and a poor one. The most recent complete season, 2025/26, delivered 450cm.

January is reliably the snowiest month, averaging 103cm and 13 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 Adelboden the snowpack peaks at an average of 257cm each season. That is among the very best we track, deeper than 95% of 40 resorts we have analysed the same way, against a median peak of 84cm.

The base is deepest in March, averaging 203cm through the month and topping out around 240cm in a typical year.

Counting any day that delivers at least 15cm of new snow, Adelboden averages 9 powder days a season. That is among the very best we track, more powder days than 95% of 40 resorts we have analysed the same way, where the median is 2 a season.

Powder days are not spread evenly. January averages 1.9 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. Adelboden averages 25 of them a season. That is among the very best we track, more than 98% of 40 resorts we have analysed the same way, against a median of 10.

January is the best month for it, averaging 4.1 bluebird days and 5.8 hours of sunshine a day.

Rain is the thing that ruins a ski week, and at mid-mountain height Adelboden sees an average of 30 days a season with at least 1mm of rain rather than snow. That is about average: 45% of the 40 other resorts we have analysed the same way see fewer wet days, against a median of 32.

May carries the most of it, with 16.1 rain days and 86mm 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.

Adelboden typically holds at least 30cm of settled snow from around 20 November through to 6 June, which works out at roughly 200 days of skiable cover in an average year. 194 of those fall inside the November to May season. On season length that is well above average compared with the 40 other resorts we have analysed the same way.

In practice that means the snow is usually gone, or going, by 6 June. 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 January. If you want fresh snow and sunshine together, January 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.
