What is the weather in Switzerland in January like?

Across all of Switzerland, January is the coldest month of the year, but conditions vary depending on exactly where you are.

Central Plateau: Bern, Geneva & Zurich

On the Central Plateau, where most of the main cities are located, January is typically a month with persistent low cloud and fog, and days can pass with no sign of the sun. It can snow, but this is often light and may not hang around for long. Temperatures usually fall below zero at night, rising to a few degrees above zero during the day.

Colder on the Jura Mountains

In the Jura Mountains to the north, it is colder than on the plateau, mainly due to higher elevations. The region is also more exposed to weather systems coming off the Atlantic Ocean and does not experience the low cloud and fog of the Central Plateau. However, snowfall is more frequent and longer lasting. Often in January, the temperature does not rise above zero during the day.

Sunnier in the Swiss Alps

In the Swiss Alps to the south, it's a different story again. At high elevations, temperatures are consistently below zero throughout the day and, when heavy clouds are not threatening to bring more snow, there is often plenty of sunshine.

In the ski resort of Crans Montana, for example, there are, on average, over four hours of sunshine a day in January, compared with just half that in cities on the Central Plateau. And regular snowfall at higher elevations usually also guarantees ideal conditions for skiing. In the alpine valleys, however, cold air often sinks to lower levels, where it produces fog and low cloud in the same way as on the Central Plateau.

Down by the lakes on the Italian border

South of the Alps, on the border with Italy, the weather is noticeably milder with daytime temperatures reaching high single figures in Celsius and remaining above zero at night. At low elevations, snow is rare, and levels of sunshine are similar to those enjoyed at ski resorts high in the mountains to the north.

Overall, January illustrates how varied Switzerland's weather can be; from fog-bound lowlands to sunny snow-covered mountains and comparatively mild southern valleys, all shaped by the country's varied terrain.
