Snow security is becoming increasingly important when choosing a ski area. The extensive SnowTrex ranking shows which ski areas offer the best guarantee for a white winter sport. The snowfall in recent years was examined, but also the possibilities for artificial snowmaking. The figures for the past five ski seasons provide insight into the snow certainty of the ski areas, view all the interesting conclusions here!
- Chamonix number 1: more than 10 meters of snow per year + mountain station at 3275 meters
- Height is crucial: the higher the ski area, the more certainty in terms of snow
- Climate change plays a role: historical data increasingly important for forecasting
- Artificial snow as a backup: SkiWelt Wilder Kaiser can snow cover 80% of 270 km of slopes in 3 days
- South Tyrol artificial snow champion: 90% of 1300 km of slopes can be covered with artificial snow
- The 3 Valleys: 8 meters of natural snow per year provides a winter paradise
Chamonix: unbeatable in snow reliability
The French ski area Chamonix is the absolute winner in terms of snow certainty. With an average of more than 10 meters of natural snow per year, you can almost be assured of excellent conditions here. Combined with a mountain station at an altitude of 3275 meters, this ski area is an exceptionally snow-sure destination.
The combination of enormous snowfall and extreme altitude makes Chamonix the most reliable choice for winter sports enthusiasts who do not want to risk disappointment. At this altitude it remains cold enough for natural snow throughout the season, while precipitation in this part of the Alps is generous.
Why height is so important
The altitude of a ski area is the most important factor for snow certainty. The higher the ski area is, the greater the chance that there will be enough snow during the main season. This is because temperatures remain lower at higher altitudes, meaning precipitation is more likely to fall as snow rather than rain. Ski areas with mountain stations above 3000 meters often offer good conditions even in warm winters. Areas with top stations below 2000 meters are increasingly struggling, especially early and late in the season.
Historical data provides a reliable picture
To determine the snow security of ski areas, SnowTrex looks at historical snowfall data from the past five seasons (2020/2021 to 2024/2025). These figures give a reliable picture of what you can expect. The average annual snowfall is calculated for the valley near the ski area.
Les 3 Vallées: 8 meters of snow
The number 1 ski area in the SnowTrex overall ranking also scores excellently on snow reliability. Les 3 Vallées receives an average of almost 8 meters of natural snow per year. This combination of enormous amounts of snow and 600 kilometers of slopes makes it a real winter paradise. With this certainty of snow, winter sports enthusiasts can be almost certain that they will find excellent conditions during their holiday. The chance of green slopes or icy conditions is minimal here.
Artificial snow as a guarantee
Not every ski area can count on 8 or 10 meters of natural snow per year. Fortunately, modern snow cannons show that you can guarantee a fantastic skiing holiday even without extreme natural snowfall. SkiWelt Wilder Kaiser -Brixental is a perfect example of this. In winter temperatures, this Austrian ski area can cover no less than 80% of its 270 kilometers of slopes completely with snow within three days. That is an impressive achievement that ensures snow certainty, regardless of what nature does.
The ski region of South Tyrol/South Tyrol in Italy is even more impressive. Here, even 90% of the almost 1,300 kilometers of slopes can be covered with artificial snow. This enormous investment in snow cannons means that winter sports enthusiasts are almost assured of good conditions, even in less snow years.
