Luxembourg, a small country between Belgium, France and Germany, has a
moderately continental climate, with cold winters and mild summers. The influence of the Atlantic Ocean is evident, but the altitude, which varies between 250 meters (800 feet) in the far south and 500 meters (1,650 feet) in the north, makes it a bit colder than the plains, with more frequent snowfalls in winter.
Precipitation in Luxembourg is quite frequent and relatively abundant, amounting to around 700 millimeters (27.5 inches) per year in the south-east and around 900 mm (35 in) in the south-west, while in the northern hilly area, it reaches 1,000 mm (40 in).
