Germany Weather, climate and geography
As with most European countries, Germany is a year-round destination but not especially dependable weather-wise. In general terms though, it's temperate throughout the country with warm summers and cold winters - prolonged periods of frost or snow are rare. Rain falls throughout the year, with much of Germany experiencing its maximum rainfall over the high summer months. Unpredictability, then, is a major factor. The average January daytime temperature is 3°C (38°F) and in July is 22°C (72°F). Extremes commonly reach -10°C (5°F) in winter and 35°C (95°F) in the summer months.
While Munich might be considerably further south than Berlin, the fact that the Bavarian capital sits at a much higher altitude means the two cities have broadly comparable summers. The highest annual temperatures tend to be in the southwest, where there’s almost a Mediterranean feel to the landscape at times. Unsurprisingly, this is where much of Germany’s wine is grown.
May through to September are the most popular months in terms of tourist numbers, and certainly hold the most appeal for visitors aiming to spend significant periods of time outdoors. However, the spring and autumn shoulder seasons also hold real attraction for those who want the promise of decent(ish) weather without the tourist levels. The winter holidays are also a big draw in their way, due in no small part to their attendant Christmas markets. Peak season for ski areas is from December through to the end of March.
Away from the mountains, January through to April will appeal to those who enjoy the benefits of uncrowded attractions, although be aware that cities like Berlin rarely witness "slow" periods at any time of year. Prices tend to be slightly higher over the summer months. One other thing to bear in mind is that hotel rates can increase when large trade shows are in town (potentially a problem in Frankfurt, for example).
European clothes according to season with light- to mediumweight in summer, medium- to heavyweights in winter. If you’re intending to visit the mountains – and particularly if you’re planning a long-distance hike – it’s best to take waterproof gear and extra layers with you, no matter what the time of year.
