Switzerland Geneva Weather in October — Climate Guide
October in Geneva is moderate
October is moderate for Geneva.
October in Geneva is mild, atmospheric autumn — averaging about 15°C/8°C, with golden foliage in the parks and Lavaux vineyards, though it turns wetter and greyer as the month goes on.
Crowds and prices ease back into shoulder season, making it good value, and the city is calmer and pleasant for the Old Town, the museums, and lakefront walks on bright days. The Jet d'Eau still runs in mild conditions. This is when cooler-weather food comes back into its own — fondue, raclette, and Geneva's longeole sausage start appearing on menus.
