Grandvalira snow history

Grandvalira averages 291cm of snowfall over a full season, measured from November to May across the last 10 winters. That is about average: more snow than 49% 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 2017/18 with 491cm, and the leanest was 2022/23 with 147cm — a difference of 344cm between a good year and a poor one. The most recent complete season, 2025/26, delivered 406cm.

March is reliably the snowiest month, averaging 61cm and 11 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 Grandvalira the snowpack peaks at an average of 77cm each season. That is below average, deeper than 38% of 39 resorts we have analysed the same way, against a median peak of 84cm.

The base is deepest in February, averaging 52cm through the month and topping out around 67cm in a typical year.

Counting any day that delivers at least 15cm of new snow, Grandvalira averages 3 powder days a season. That is about average, more powder days than 59% of 39 resorts we have analysed the same way, where the median is 2 a season.

Powder days are not spread evenly. March averages 0.8 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. Grandvalira averages 13 of them a season. That is above average, more than 62% of 39 resorts we have analysed the same way, against a median of 9.

March is the best month for it, averaging 3.1 bluebird days and 9.2 hours of sunshine a day.

Rain is the thing that ruins a ski week, and at mid-mountain height Grandvalira sees an average of 34 days a season with at least 1mm of rain rather than snow. That is about average: 54% 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 13.4 rain days and 70mm 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.

Grandvalira typically holds at least 30cm of settled snow from around 10 January through to 17 March, which works out at roughly 67 days of skiable cover in an average year. 71 of those fall inside the November to May season. On season length that is below 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 17 March. 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 February. If you want the best chance of fresh snow, go in March. 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.
