Introduction



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).

Winter, from December to February, is cold and dull. In the capital, the average temperature in January and February is around freezing (0 °C or 32 °F) or slightly higher. When Atlantic currents become more intense, there can be mild days, though cloudy and windy. On the contrary, when currents from eastern Europe prevail, the temperature can dip well below freezing.
Spring, from March to May, is initially cold, and then becomes gradually cool and later mild: in the capital, the maximum temperatures are around 13 °C (56 °F) in April and around 18 °C (64 °F) in May. However, the weather is unstable, and while until mid-May it can still be cold, in the second half of May, on sunny days, thunderstorms can erupt in the afternoon.
Summer, from June to August, is mild or pleasantly warm, with cool nights and pleasant days: the minimum temperature hovers around 13 °C (56 °F) and the maximum temperature around 23 °C (73 °F). There is no shortage of cool and rainy days, when the country is affected by Atlantic fronts, but they alternate with sunny and warmer days. Sometimes, the temperature can reach 30/32 °C (86/90 °F), though these hot days are fairly rare.
In Autumn, from September to November, the weather is often gray, wet and rainy, especially in the second part, and windy at times.
