Country Summary

This page presents high-level information for Luxembourg's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates except for those in the E group are assigned a seasonal precipitation sub-group (second letter).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Luxembourg's country context and climate is provided following the visualizations.

Luxembourg is a landlocked country with a territory of 2,586 km2 located in Western Europe, between France and Germany. Of the total area of Luxembourg, 85.5% was agricultural land (51%) and land under forest (35%). The built-up areas occupied 9.5% of the total surface and land covered by water and transport infrastructure about 5%. Between 2990 and 2016, Luxembourg’s population grew at an average annual rate of 1.7%, reaching 590,700 inhabitants in 2016. This increase was mainly due to immigration. Luxembourg’s GDP reached over $62 billion in 2017 and has a GDP per capita (PPP) of about $105,000. The climate in Luxembourg can be characterized as a moderate oceanic Western European climate with mild winters and comfortable summers. Effects of climate change have already been observed. Annual mean temperatures for Luxembourg-City are now usually above the 30 years averages of the last century. Yearly averages increase is mainly driven by higher air temperatures during winter seasons. Luxembourg submitted its Nationally Determined Contribution (NDC) as an EU Member State in 2015 and its Seventh National Communication in 2018.
