The Kaiserstuhl is one of the warmest regions in Germany. The winters are relatively mild for the area, and the summers are warm or even hot, with possible average temperatures of over in July and August. Because of its loess covered volcanic soils it is a very good wine-producing region. The climatic situation of the Kaiserstuhl is outstanding in the area. It is rain-shadowed by the Vosges Mountains, under the climatic influence of the Belfort Gap and is characterized by a drier and hotter climate, which one would rather expect not to be typical of the area. Despite this, winters remain cold and dry, and summers wet, in comparison with Mediterranean climate (which instead has a rainfall peak during winter, which can see few frost days, and a dry season in summer).
