Thanks to the surrounding mountains and the Geneva Lake the temperature is very pleasant almost throughout the year. However, there are a few tricky months to avoid. So do read this rough guide before planning your trip.
Rains: The rainiest months are September and October. It is best not to dampen your holiday by visiting in these two months as the weather is gloomy on the best day.
Winter: Barring January and February when it is extremely cold, all other winter months are not at all a bad idea to travel. Winter sits well on this lovely city and you will find a lot to see and do during winter.
Summer: The best time to visit is in summer (June, July and August), when the humidity is low and cool breezes blow from the lake. It is also when Geneva will be the most crowded so be sure to book well in advance.
