Bonn Weather, When to Go and Bonn Climate Information
(Bonn, North Rhine-Westphalia, Germany, DE)



The weather in Bonn is typical of what can be expected in Germany, being rather fickle at times. Most people tend to visit the city of Bonn between the months of May and September, when the climate tends to be at its most stable, the days are at their longest and sunny weather is most likely.

During the summer months, many beer gardens and cafes with al fresco areas quickly fill up, and a range of outdoor events take advantage of the fine weather all around the Bonn area. However, don't be lulled into a false sense of security, as rainy weather is often quite random and a quick shower can be rather unexpected and dampen even the sunniest of days.
