The summer of 2024 in Luxembourg was characterised by average warmth and slightly below-average rainfall as reported by Meteolux.

Summer has officially ended, at least from a meteorological standpoint, making it the perfect time to review the national weather agency's climate data report.
 
The summer season, which ran from June 1 to August 31, was analysed and compared to the climate data from the reference period of 1991 to 2020 for a clearer understanding of recent trends. All data was collected at Findel Airport, where Meteolux is situated.

Overall, the summer of 2024 in Luxembourg was relatively typical, marked by some extreme weather events but otherwise average climatic conditions.
