Best Time to Visit
Best Months
May, June, September, October
Mild temperatures (16-22°C), manageable crowds, blooming landscapes in spring, and golden colours in autumn make these months the sweet spot for city sightseeing and Bernese Oberland exploration. Mountain trails are fully open and Jungfraujoch views are typically clearest.
Months to Avoid

November is grey, wet, and cold with reduced daylight; January and February bring the coldest temperatures and many tourist facilities in the Bernese Oberland at capacity with ski visitors while city attractions are quiet but limited.
