Regulars are specific this has a genuine microclimate that forecasts don't always capture accurately, showers predicted for the wider region often missing Montreux itself thanks to its sheltered position at the foot of the Prealps. Our row backs that mild, genuinely wet read, 17.5C over 10.9C nights feeling 9C, with a substantial 180.3mm of rain across 19.2 days and a trace of late-season snow, 4.3cm, likely confined to the surrounding peaks rather than the lakeside town. Regulars are consistent this counts as the wettest month of the year here by the numbers, even though the town's own French-Riviera-like ambiance and architecture can make a sunny stretch feel more Mediterranean than Alpine. Temperatures also climb steadily through the month, the warmest days typically arriving toward the very end. The record: 10.5 hours of sun, humidity 80 percent and AQI 42.

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.
