The majority of Germany has a moderately continental climate with cold winters and warm summers. Northern Germany has mild weather, but it rains more often and is windy due to the Atlantic Ocean. South central Germany has a mountainous climate with weather that becomes colder as you climb to higher altitudes.
Weather in Germany can be unstable with periods of fog, snow and thunderstorms. Snowfall is common in the winter, especially in mountain areas. It is more likely you will see significant snow from Bavaria to the eastern plains and up the Baltic Coast. There are also cold waves from Siberia that can make it extremely cold in the northern and central portions of Germany. These waves can last for a few days although they can last longer in Bavaria where cold air tends to stagnate.
The best time to visit Germany is in late spring, May and June, or early fall, September and October. The harvest season is extremely popular in Germany and the ski season in the Alps runs from Christmas until the end of March. During those periods, you may find tourist attractions more crowded.
The best way to get around Germany is by using public transportation which is ranked as one of the best in the world. The Schnellbahn or Stadtschnellbahn, known as the S-Bahn is the fastest form of transportation, serving a wider metropolitan area and linking suburbs to city centers. The Untergrundbahn, or U-Bahn, is an underground subway or metro, often called “The Tube.” Trams, similar to streetcars in the United States, ravel on rails along regular roads and stop at multiple locations throughout the city. There are also buses that link suburbs that are well outside the city center. Many operate late at night when other forms of public transportation stop running. There are also regional trains that service cities and suburbs in Germany.
