Val d’Isere weather & snow conditions

Due to the altitude of Val d’Isere’s trails, snow conditions are more reliable than at many other ski resorts and its snow record is exceptional. The area’s unique micro-climate is immune to Atlantic depressions and gets its weather from both directions, a benefit to early and late season skiers. In winter, precipitation even in the valley falls as snow, with depths of over 10m, although mean winter temperatures here are rising. At the 2,000m level, good coverage here lasts from November to May.

Given the inevitability of low-snow winters, Val d’Isere protects its on-piste slopes with strategically-placed snow machines. Weather patterns here are subject to frequent and dramatic change, including long-lasting thick fog due to temperature inversions. Skiers on the high slopes are often faced with masses of cloud in the valley on their return.

Snow conditions are affected by the spring Fohn winds, known as ‘snow-eaters’, accompanied by low pressure troughs and low humidity along the sheltered leeward slopes. Temperatures can rise quickly by as much as 15˚C, making the snow surface unstable and increasing the risk of avalanches. Changes may last for several days.
