The city is located in the west of Switzerland, in the canton of Vaud, on the north shore of Lake Geneva, at an altitude of about 500 meters or 1,650 feet (the shores of the lake are at 380 meters or 1,250 feet), in an area with a microclimate somewhat milder than in other cities in Switzerland.
The winter is cold and gray. There may be relatively mild periods, when Atlantic currents prevail, and other colder periods, when the temperature drops below freezing. On average, 35 cm (14 in) of snow fall per year: outside the Canton of Ticino, we are at the lowest levels of Switzerland.
Sometimes, there can be cold spells, in which there is an freezing wind, the Bise, which blows from the plains of Eastern Europe.

In summer, the temperatures are generally pleasant and lend themselves to outdoor activities, although sometimes there can be rains and thunderstorms.
At times, hot periods can occur, generally of short duration, which in recent years are becoming more frequent due to global warming, and in which the temperature can exceed 32 °C (90 °F). The temperature reached 37 °C (98.5 °F) in August 2003 and 36 °C (97 °F) in July 2015, while in 2022 it reached 35 °C (95 °F) in July and 34.7 °C (94.5 °F) in August, but otherwise, it generally does not go above 33/34 °C (91/93 °F) on the hottest days of the year.
