The northern half of Germany has many similarities with ie. the Dutch maritime climate. The winters are fairly mild and the summers are not too hot. Rainfall, usually rain, is spread evenly throughout the year.
The south and southeast of Germany has more a continental climate. The winters are colder with a lot of snowfall and the summers are warmer. The rain falls mainly in (heavy) showers.
The climate in the mountainous regions is on average colder than in the surrounding lower areas. There is more snow, which stays there for a long time.
The southern Rhine Valley is considered to be the warmest and sunniest part of Germany (considered throughout the year).
