When to fly
July and August have the best weather and the biggest crowds and is normally the most popular time to book flights to Geneva. The beginning of August marks Swiss National day with two weeks of festivities. Cheap flights to Geneva are not likely to be found during these summer months as the city is packed with events, especially music festivals.
Every year in June, the Societe Nautique de Geneve welcomes Bol d’Or participants’ friends, families, supporters and fans from all over the world to come and enjoy the popular and exciting event. With over 500 boats racing across Lake Geneva, the annual Bol d’Or Mirabaud Regatta is home to Europe’s largest regatta in enclosed waters. Spectacular scenes see participants travel the length of the lake to a turning point at the half way mark, Le Bouveret, before making the return sprint back to Geneva. Following the thrill of the event is a huge celebration at several different after parties.
Flight bookings peak again during the Christmas and New Year holidays. The celebration of l'Escalade in December with its costumed and torch-lit processions brings throngs of visitors to the city.
The shoulder months of June and September are pleasant times to visit and slightly lower hotel rates and cheaper Geneva flights can be found.
October, November, April, and May have fewer crowds, and usually the lowest rates, although some hotels are closed during the low season.
Summer (July through August) is warm with temperatures in the mid-20s and July can be in the upper 20s and hot. Autumn (October through November) is mild as temperatures drop to the low 20s and into the low teens in October. Winters (December through February) are cold with daytime temperatures ranging from the very low single digits, and when the bise (north wind) blows, it can be bitterly cold. Spring (March through May) is mild with temperatures reaching the teens. Rain falls year-round, and September usually gets the most rain
