Snow depth in Alt St. Johann
Snow is what makes a ski holiday special. Ideally, we wake up every day to Kaiser weather: a layer of fresh snow, bright sunshine, and a clear blue sky. However, icy temperatures and heavy snowfalls are also part of the experience. Or those foggy days when you ski from hut to hut, warming up with a cup of coffee, tea, or hot chocolate. When it comes to winter sports, the weather can be unpredictable, and nothing changes more rapidly than mountain weather.
