Bern weather by month
Averages for 1991–2020 at the BernZollikofen weather station (553 m above sea level), from the WMO climate normals, next to each month's share of Switzerland's tourist nights (Eurostat, 2025) in 2025.

Golden hour
Evening golden hour is our calculation for the 15th of each month of 2026: the time the sun takes to go from 6° above to 4° below the horizon (there is no official definition).
The quietest and busiest months
In 2025, November was Switzerland's quietest month (4.2% of the year's tourist nights): at Bern's station that month averages a high of 7.7 °C, a low of 1.0 °C and 77 mm of rain. July was the busiest (12.9%): average high 24.6 °C, average low 13.0 °C, 108 mm of rain. The visitor figures are for the whole country, and they do not show that the weather makes a month busier or quieter, so we do not say it does.

July was Switzerland's busiest month in 2025 (12.9% of its tourist nights). These places had an average high within 2 °C and rainy days within 3 of Bern's in July, in a different country, and July took a smaller share of its 2025 tourist nights than July did of Switzerland's:
- Düsseldorf, Germany: average high 24.7 °C, 10.6 rainy days; July was 11.7% of Germany's year.
- Eindhoven, Netherlands: average high 24.0 °C, 10.6 rainy days; July was 11.7% of Netherlands's year.
