Although snowfall is unpredictable at long range, regular patterns do emerge over a number of seasons.
Using this data, you can tell if your preferred travel dates correspond with previous good snow conditions.
As with all the Andorran ski stations, quantity of snowfall is not normally a problem, but the southerly latitude does mean that any unpisted snow deteriorates rapidly in direct sunlight. The station is very adept at maintaining the conditions of the pistes, and a massive network of snowmaking cannons secures the majority of the ski area, including all principal home runs.
As long as there are sufficient snowfalls and/or low temperatures in the pre-season weeks to establish a sound base, then the majority of the pisted ski area can be relied upon to be open for the rest of the season. The average depth of pisted snow is regularly over the one-metre mark.
The graph below illustrates snow depth in centimetres, as measured at set points on the lower and upper slopes; figures are taken from official station communiqués.
The magic figure is 100 cm (39 in): once snow depth exceeds that mark, conditions will generally be good throughout the ski area and will usually remain so for an extended period of time.
