The most popular time to visit Bern is during the summer months, particularly July. This is when the city comes alive with vibrant festivals, outdoor activities, and a delightful climate, with average temperatures around 72°F. The warm weather creates the superb backdrop for exploring Bern's stunning medieval architecture, lush parks, and picturesque riverbanks.
During the peak season from May to July, tourist activity increases significantly. This bustling atmosphere is accompanied by a variety of cultural events, open-air markets, and local celebrations that allow visitors to immerse themselves in Swiss traditions. For those who appreciate outdoor adventures, July offers abundant opportunities to enjoy Bern's beautiful surroundings, whether it's a leisurely walk along the Aare River or a scenic hike in the nearby hills.
If you're looking for a more budget-friendly option, consider visiting in late September. While the crowds have thinned out, the weather is still pleasant, with temperatures in the mid-60s Fahrenheit. This time allows you to enjoy the beauty of Bern without the peak season hustle, and many local establishments may offer special promotions to attract visitors.
