Is September Right for You?
Weigh the advantages and considerations before booking
- + Lake Léman stays warm enough for swimming through mid-September, water temperature holds at 20°C (68°F) and locals still crowd the Pully and Lutry lidos on weekends
- + Vendanges (grape harvest) transforms Lavaux into a working landscape of tractors, hand-picked chasselas grapes, and open-air lunches in family vineyards that tourists never see in summer
- + Hotel rates drop 25-30% after August 31st while most outdoor cafés along Rue de Bourg remain open and the sunset over the cathedral still hits at 7:30pm
- + Montreux Jazz Festival's smaller September edition brings free concerts to Parc de Valency without the summer crush, you can find a seat at the lakeside stage
- − Morning fog rolls down from the Jura and can sock in the lake until 10am, which means your sunrise photos from Sauvabelin Tower might look like you're floating in milk
- − University students return mid-month and suddenly the M2 metro feels like Tokyo at rush hour between 8-9am and 5-6pm
- − Some of the vintage funiculars, the one up to Signal de Sauvabelin, close for annual maintenance, forcing longer walks or bus rides
Best Activities in September
Top things to do during your visit
September is when the terraces between Lausanne and Montreux turn into a patchwork of gold and green, with the air thick with the smell of crushed grapes. The harvest trails from Grandvaux to Dézaley are still accessible but you'll share them with pickers rather than tour groups. Morning light on the stone walls makes the villages look like they've been dipped in honey.
The lake hits its warmest temperatures in early September, and the morning fog burns off by 10am to reveal mirror-calm water good for paddling past the Olympic Museum. Locals know the shallow shelf at Ouchy stays comfortable until the third week, when the first autumn winds start whipping up whitecaps.
Cooler September mornings make wandering the Escaliers du Marché manageable, the covered arcades smell of roasted chestnuts and Gruyère from the Tuesday/Friday market. The tour timing works because shops aren't slammed with cruise passengers like July, so you can talk to the chocolatier at Durig who'll let you taste single-origin bars while he explains the September harvest.
The Jura's beech forests start turning rust-colored in mid-September, and the air is crisp enough to make the 800m (2,625 ft) climb to Mont Tendre feel refreshing instead of brutal. Alpine huts are still serving melted raclette from summer milk, the flavor is richer than winter cheese because the cows were still eating fresh grass.
September Events & Festivals
What's happening during your visit
Lutry's grape harvest festival transforms the lakefront into three days of wine tents, marching bands, and open cellars. The Saturday evening parade features vineyard workers in traditional blue smocks handing out glasses of chasselas to the crowd, arrive by 6pm to stake out space near the harbor.
