Luxembourg weather overview

Although only tiny, Luxembourg, which lies between Belgium and France, manages to encompass a wide range of climatic conditions. Its north, which lies in the densely wooded hills of the Ardennes, is wetter than the south, whose eastern part lies in the balmy Moselle Valley. Here, summers are warm to hot and autumns mild enough to allow the cultivation of grapes for wine making. Winters, however, can be very cold on occasion.
