Climate and weather in Luxembourg
Yellow alerts from Meteolux, floods in spring and occasional miracle snow that you will see immediately on the Instagram of every self-respecting Luxembourger. The weather in Luxembourg can be unpredictable, but predictably you'll learn all about the climate in the country from our article.
Luxembourg has a mild climate with moderate seasons and temperatures. It rains a lot here, and it's always humid. The climate in Luxembourg is affected by the Atlantic Ocean and west winds, which bring humid air and clouds. Luxembourg City has an average temperature of 0°C in winter and 25°C in summer. It rains all year, but it is wettest in May and June. Snow is common in winter but melts fast.
Climate in the Grand Duchy of Luxembourg
Luxembourg does not have a clear climatic definition, you can think. Its climate can be conditionally called moderately marine. It is best described by mild winters and not extremely hot summers, which is confirmed by the average annual temperatures: normally they range from -2.6 °C to 21.6 °C.
The continental climate of the Eastern European plains confronts it and affects the general rules. It's sunny in summer, especially in July. Luxembourg enjoys an Indian summer in September and October. An Indian summer is warm and dry weather in late autumn or early winter.
Winter temperatures here range from +3°C to -6°C which is not too bad, if you have a couple of warm coats. The coldest month of the year is January. The climate in the Grand Duchy is strongly influenced by the country's terrain. For example, temperatures in the north are 2 to 3 degrees lower than in the south, due to the mountainous terrain in the north and the Luxembourgish plateau and plains in the south.
Climate in Luxembourg's regions
The Grand Duchy is divided into 5 natural regions: they are Guttland, Éislek, Minett, Moselle, and Mullerthal. Each of them contains different communes, and various touristic destinations, as well as different natural resources.
Guttland
This region is located in the central part of the country and is best described by gently rolling hills and fertile agricultural land. It is home to several small towns and villages, as well as the country's capital city, Luxembourg City. Guttland is also known for its dense forests and numerous hiking trails.
Good land
Guttland is literally translated as «good land». The topography is mostly flat: meadows, fields, vineyards, and forests. But Guttland is more urbanized than Éislek. Consequently, there are fewer forests and they grow in the northern part of the region.
The climate here is softer, with fewer temperature fluctuations. That means softer winters with almost no snow, and warmer summers.
Éislek
Also known as the Oesling, this region is located in the northern part of the country and is characterized by rugged hills, dense forests, and deep valleys. It is home to several small towns and villages, as well as the town of Clervaux and its famous castle. Éislek is also known for its natural beauty, including the Our River and the Ardennes forest.
The climate in Éislek is more severe than in the rest of the country. The northern part of the region has the coldest and most humid weather in all of Luxembourg. Ardennes, a mountain chain and a land of vast forests lie on the border of France, Belgium, and Luxembourg. It often snows in the winter here.
Forest lands
In comparison with Gutland, the region is mostly hilly and more heavily forested: birch, oak, and pine forests can be great places to enjoy nature here.
Minett
This region is located in the south of the country and is described by a landscape of former industrial sites and mining towns. It is home to several important historical and cultural landmarks, including the city of Esch-sur-Alzette and its steelworks, the National Mining Museum in Rumelange, and the Fond-de-Gras railway museum.
Moselle
This region is located in the east of the country and is full of steep vineyards and picturesque villages along the Moselle River. It is home to several important wine-producing towns, including Remich, Grevenmacher, and Wormeldange, as well as the historic city of Trier, located just across the border in Germany.
Mullerthal
Also known as Luxembourg's Little Switzerland, this region is located in the east of the country and is characterized by a landscape of rocky cliffs, dense forests, and winding rivers. It is home to several scenic hiking trails, as well as the town of Echternach and its famous dancing procession.
The biggest areas of natural regions in Luxembourg are Éislek and Guttland. Éislek includes 3 northern cantons Clervaux, Vianden, and Wiltz. It also partly includes Dikirch and Rodange. Guttland includes Echternach, Grevenmacher, Remich, Capellen, Esch-sur-Alzette, Luxembourg, and Mersch.
Corn fields and cows
The area between Éislek and Guttland is a major agricultural region of the country due to its rich and varied soil.
What weather to expect in Luxembourg during different seasons?
Luxembourg has four distinct seasons, each different. Demi-seasons are rainy and changing, while mild winters can sometimes surprise you with decent amount of snowing. Summer, though often not too hot, is sunny and warm.
Winter
During winter, which lasts from December to February, temperatures are usually cold and there is occasional snowfall. However, in recent years, winters have become milder and there has been less snowfall due to climate change.
Spring
In spring, from March to May, the temperatures are mild, there is an occasional rainfall and even heatwave. The earlier onset of spring and earlier blooming of plants can be seen here, due to climate change. As well as affecting flora, it affects fauna too — a lot of birds, like cranes, migrate later in the fall, fly farther, and return in the spring with the first days of good weather. Frosts are not as much of a problem for them as the lack of food.
Summer
During summer in Luxembourg, which lasts from June to August, the weather is generally warm and humid with occasional thunderstorms.
Autumn
Autumn, from September to November, is described by mild temperatures, occasional rainfall, and leaves on the trees turning vibrant colors.
Overall, if we are talking about climate change, affecting the whole planet, the climate in Luxembourg is changing too, with temperatures increasing and rainfall patterns becoming more unpredictable. This has significant implications for agriculture, water resources and the environment in Luxembourg.
