ローザンヌ 1月の天気

Gstaad's forum has a thread specifically for visitors who aren't skiing, which tells you something useful: regulars point non-skiers toward the fondue hikes and the valley's hiking trails, with the Château-d'Oex hot air balloon festival a genuine draw if your January dates happen to overlap it.

Forum posters describe Lausanne as sharing Geneva's general winter pattern but with noticeably less fog, since the wider Swiss plateau and Geneva itself can sit under low cloud for days at a time in December. Posters note it seldom drops below freezing in low-lying lakeside spots like Lausanne, and some winters bring little or no snow at all right in the city center, even though the region's full climate record shows meaningful average December snowfall and a fairly high number of rainy days overall - Lausanne's lakeside elevation runs milder and snow-uncertain compared to nearby higher ground. Posters are enthusiastic about December as Christmas market season, with especially large ones in Basel, Bern, Zurich and nearby Montreux worth combining with a Lausanne base. Posters generally rate December as cold, often grey and snow-uncertain for Lausanne itself, workable and increasingly festive as the Christmas market season gets underway.

Forum posters put early June around 15-25C and call it beautiful without being too hot, though they're quick to flag that Swiss weather is genuinely unpredictable and varies a lot by altitude - expect a real mix of warm sun, rain, and the occasional thunderstorm within the same trip. Layered clothing plus sturdy waterproof shoes are the standard packing call. June draws noticeably fewer crowds than peak summer, though the city's jazz festival dates are worth checking in advance if avoiding a busier stretch matters to the itinerary.
