Snow Forecasting
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.

Arcalís
The well-documented microclimate at Arcalís, and the resulting lack of extreme temperature swings, helps to protect piste conditions following snowfalls.
Lack of snow has never really been a problem, and the station quickly becomes a magnet for visitors whenever other Pyrenean ski areas experience snow droughts and/or poor piste conditions.

Late February to early March is the most likely time to get good snow, with conditions only beginning to deteriorate in late March; nevertheless, increasingly reliable end-of-season dumps are always a strong possibility.

Snow-Depth Statistics
The graphs below illustrate 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.
