How these numbers are calculated
Powder day — at least 15cm of new snow in 24 hours.
Bluebird day — sunshine for at least 60% of daylight, following at least 10cm of snow over the previous 3 days.
Rain day — at least 1mm of rain (not snow) at this elevation.
Skiable day — at least 30cm of settled snow on the ground.
Snow depth is modelled from Open-Meteo / ERA5 reanalysis at 2450m, not measured at the resort. Use it to compare seasons and resorts; use the resort's own report for today's conditions.

Is Les Deux Alpes a good place to ski?
heavy snowfalla deep, reliable basefrequent powder daysplenty of bluebird daysvery little raina long season
On 10 years of record, Les Deux Alpes stands out for heavy snowfall, a deep, reliable base, frequent powder days, plenty of bluebird days, very little rain and a long season.
All of these figures come from 2450m, the mid-mountain height, and describe an average year rather than the one you are about to book. Snow depth here is modelled from reanalysis rather than measured on the hill, so treat it as a guide to how Les Deux Alpes usually behaves, not as a forecast.
Les Deux Alpes snow record in detail
How much snow does Les Deux Alpes get?
Les Deux Alpes averages 656cm 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 2017/18 with 939cm, and the leanest was 2016/17 with 444cm — a difference of 495cm between a good year and a poor one. The most recent complete season, 2025/26, delivered 643cm.
December is reliably the snowiest month, averaging 145cm and 12 days with fresh snow.
How deep does the snow get at Les Deux Alpes?
Snowfall totals flatter resorts that lose their snow quickly, so the more useful number is how deep the settled base actually gets. At Les Deux Alpes the snowpack peaks at an average of 195cm each season. That is among the very best we track, deeper than 90% of 40 resorts we have analysed the same way, against a median peak of 84cm.
The base is deepest in March, averaging 157cm through the month and topping out around 179cm in a typical year.
How many powder days does Les Deux Alpes get?
Counting any day that delivers at least 15cm of new snow, Les Deux Alpes averages 13 powder days a season. That is among the very best we track, more powder days than 98% of 40 resorts we have analysed the same way, where the median is 2 a season.
Powder days are not spread evenly. December averages 3.2 of them, which is the single strongest argument for timing a trip around the middle of the season rather than the edges.
How often does Les Deux Alpes get bluebird days?
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. Les Deux Alpes averages 30 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.
December is the best month for it, averaging 5.9 bluebird days and 5.9 hours of sunshine a day.
Does it rain at Les Deux Alpes?
Rain is the thing that ruins a ski week, and at mid-mountain height Les Deux Alpes sees an average of 18 days a season with at least 1mm of rain rather than snow. That is well below average: 20% 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 10.0 rain days and 44mm 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.
When is the best time to ski Les Deux Alpes, and when does the season end?
Les Deux Alpes typically holds at least 30cm of settled snow from around 23 November through to 19 May, which works out at roughly 179 days of skiable cover in an average year. 184 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 19 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, December 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.
Comparisons use 40 resorts across 18 countries, each measured over 5 recent seasons at mid-mountain height. Glaciated locations, where the model never melts the snow out, are excluded. Figures for Les Deux Alpes are taken at 2450m. Corpus last rebuilt 2026-09-02.
