Current Climate


This page presents Luxembourg's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit.  Other historical climatologies can be selected from the Time Period dropdown list. Data for  specific coordinates can be downloaded for in the Data Download page.

Observed, historical data is produced by the Climatic Research Unit (CRU) of University of East Anglia. Data is presented at a 0.5º x 0.5º (50km x 50km) resolution.

The climate in Luxembourg can be characterized as a moderate oceanic Western European climate with mild winters and comfortable summers. Luxembourg is situated in a cool climate region since its annual average air temperature is below 15°C: 8.3°C for the reference period 1961-1990.


  • Annual mean temperatures for Luxembourg-City are now usually above the 30 years averages of the last century. Indeed, the 1951-1980, the 1961-1990, the 1971-2000 or the 1981-2010 mean yearly temperatures for the capital city – around 9°C – are nowadays regularly exceeded. 
  • Yearly average increase is mainly driven by higher air temperatures during winter seasons. 


  • With regard to other meteorological parameters – rainfall, sunshine hours, relative humidity – no clear trends can be identified yet, probably because the very small size of the country (2,586 km2) limits the identification of such changes.
