Summers here can be quite warm and damp, as this season is Switzerland’s wettest period of the year. Much of the summer rainfall is heavy and can be accompanied by severe thunderstorms. Spring and fall are drier and cooler. In Zurich, winters are warm and sunny and winters are cold with temperatures dropping as you approach the eastern mountains. Like other parts of west-central Europe, Switzerland is open to climatic influences from the Atlantic and from Eastern Europe.
