High / low are average daily temperatures (°C). “Feels” reflects how hot or cold it feels, allowing for humidity.
Swiss Plateau (Mittelland)
Deep winter often settles over Zurich, Bern and Basel with chilly, damp air and frequent morning fog that can hang over the lowlands for days. Temperatures typically sit around 0-5°C, and snowfalls are intermittent rather than persistent - when it does fall, urban streets get slushy quickly. Pack layered, waterproof clothing and expect slower regional trains during cold snaps; museums, cafés and the lakeside promenades are calm and easy to explore without crowds.
Lake Geneva & Western Switzerland (Geneva, Lausanne, Montreux)
A very mild winter characterises Geneva and the shores of Lake Geneva, with temperatures around 0-6°C and more rain than heavy snow at lakeside elevations. The powerful northeast bise wind can make the air feel much colder but also clears pollution, giving crisp visibility toward the Jura. Lakeside promenades and museum visits are comfortable with a warm coat; vineyards of Lavaux look dormant but atmospheric.
Bernese Oberland & Central Alps (Interlaken, Jungfrau, Engelberg)
High-altitude winter conditions dominate the Jungfrau region in January: thick snowpack in Grindelwald, Wengen and Mürren and reliable skiing on the mountain slopes. Temperatures in valley bottoms like Interlaken sit around −5 to 0°C, but on the peaks it’s bitterly cold; frequent snowfall and clear, crisp days after storms produce iconic snowy vistas. Avalanche safety closes some backcountry routes - follow local guidance and bring layered winter gear and crampons if venturing off marked trails.
Valais & High Alps (Sion, Zermatt, Saas-Fee, Matterhorn)
January is full winter high up in Valais: Zermatt and Saas-Fee have deep, stable snow and a strong alpine microclimate that keeps skies often clear. Low Rhône valley towns like Sion are usually colder at night but sunnier and drier than northern regions, reflecting the Valais rain shadow. Expect bustling ski resorts, excellent piste conditions, and bright afternoons ideal for panoramic photography - pack ski gear and sun protection.
Ticino & Southern Lakes (Lugano, Locarno, Lake Maggiore)
January in Ticino feels noticeably milder than northern Switzerland: Lugano and Locarno average around 3-8°C and snow is rare at lake level, though the surrounding mountains get snow. The landscape keeps a Mediterranean edge - palm trees and citrus in sheltered gardens - and winter walks along Lake Lugano can be pleasant on sunny days. Bring a warm coat for chilly mornings and a lighter layer for sunlit afternoons.
Eastern Alps - Graubünden & Engadin (Davos, St. Moritz, Chur)
January in Graubünden is full alpine winter: St. Moritz and Davos sit under regular snow with excellent piste conditions and very cold nights, often dropping well below freezing. The high-altitude Engadin valley is notably sunny and dry in winter, making it ideal for cross-country skiing and winter walking. Layers, strong sun protection for snowy glare, and reservations at winter hotels are advisable during the holiday season.
