Snow depth in Unterwasser

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. In addition to the forecast for the coming days, the current snow depth is a key part of the weather report in Unterwasser. How much snow is there on the mountain and in the valley of the Toggenburg ski area? Check the table below to see the current snow depth in Unterwasser.

Explanation of the weather forecast in Unterwasser

The weather report for Unterwasser is updated daily and is carefully compiled by meteorologists working with Snowplaza. Curious about the forecast for the next two days? Check out the 48-hour weather forecast, which provides information for the morning, afternoon, evening, and night. The symbols indicate whether snow or rain is expected, whether it will be cloudy, or if the sun will be shining. Click on "village" to see the weather conditions in the valley, and on "mountain" for forecasts at higher altitudes. The zero-degree line indicates the frost line, which changes depending on the temperature. Don't confuse it with the snowline—snow can still fall several hundred meters below the zero-degree line.
