The climate in Bamberg is generally pleasant and humid. The city faces rainfall throughout the year. Spring and summer would ideally be the best time to visit this city. However, the month of Christmas is celebrated richly in the town so December would also be a recommended season to make a trip to Bamberg, Germany. The weather during Christmas season is pretty cold so make sure you come prepared with extra layers of warm clothing. As it rains throughout the year, a raincoat or an umbrella is much recommended as well.
