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.
Snow cover during Christmas and New Year has generally secured the launch straight into high season, with the February school holiday period also having good conditions. Records also confirm the sound predictability of late spring snowfalls, often resulting in the best conditions of the season.
The seasonal pattern is fairly robust: mid- to late-March is always a good bet, with the bonus of cheaper holiday packages at that time of the season too.
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.
