The majority of Germany lies within the moderate, maritime climatic zone. Large fluctuations in temperature are rare. Rain falls throughout the year. The average winter temperature is +2°C on the North German Plain and - 6°C in the mountains. Average temperatures in July range between +18°C on the North German Plain and +20°C in the sheltered valleys of the south. Exceptions include the upper Rhine plains with their 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 have their own microclimate with harsh winds, cool summers and snowy winters.
