The months of May to October bring the best weather. In mid-summer shorts can be just as appropriate as an umbrella. Average temperatures in July lie at around 20 °C in the lowlands and around 25 °C in the sheltered valleys of the south.
In contrast to many other countries Germany does not have one particularly rainy month. Rainfall can be expected during all seasons.
Autumn is the time to enjoy romantic Germany. The foliage is turning golden, the climate is still agreeably mild for getting out and about. Winter sports buffs will enjoy themselves best from December to March.
Exceptions to the rule include the upper Rhine plains with a very mild climate, Upper Bavaria which is influenced by the föhn, a warm Alpine wind that blows in from the south, and the Harz mountains, which has its own microclimate with harsh winds, cool summers and snowy winters.
