Snow and Weather Conditions
The French Alps receive substantial snowfall from Atlantic and Mediterranean storm systems. High-altitude resorts benefit from reliable natural snow, while purpose-built ski stations ensure slope-side convenience. At this extreme altitude, temperatures stay well below freezing for much of the season, preserving snow quality and enabling a long winter with deep, reliable snowpack. The high-alpine climate means precipitation often falls as dry, light powder even during milder weather events. Cumulative seasonal totals routinely top 8-12 metres, packing down into a base layer 3-4 metres deep by mid-winter.
