Swiss Alps in January — Full Picture
January is peak ski season in the Swiss Alps. The valley bases sit around 3°C/-3°C with reliable snow, while the high summits are deep in winter — Jungfraujoch and Gornergrat are well below -10°C with snow and ice year-round anyway.
If you ski or snowboard, this is prime time: Grindelwald, Wengen, Mürren, and Zermatt are all in full operation, and the Lauberhorn World Cup races at Wengen (mid-January) are a major event. The villages look their festive best under snow.
For non-skiers it's a quieter call — the summit railways still run for the views (Jungfraujoch, Gornergrat, the Matterhorn), and Gornergrat's winter return fare (~CHF 96) is cheaper than summer. But days are short and often grey, and the cold is serious.
Note: the New Year week brings peak crowds and top pricing; book months ahead. Mountain weather closes lifts in storms — keep summit days flexible and check forecasts. Verify all current fares.
What to Wear & What to Pack
Deep winter in the valleys (around 3°C/-3°C) with snow; far colder on the summits (Jungfraujoch well below -10°C). Down jacket, thermals, hat, gloves, scarf, and proper snow boots. Layers for the cold, dim, often cloudy days.
