The Ministry of Agriculture, the Water Management Authority (AGE), and metereological service Meteolux have presented the meteorological bulletin for winter 2025/2026. Overall, the season was milder and drier than the long-term average for 1991–2020. The end of the year in particular was characterised by moderate temperatures.

At the beginning of 2026, temperatures fell slightly, with January close to seasonal norms or slightly below depending on the region. In February, however, temperatures once again rose above the seasonal average, reflecting the general trend observed throughout the winter.

In terms of precipitation, the winter overall was drier than the 1991–2020 average. A rainfall deficit was recorded nationwide in December, and January showed a similar pattern across most regions.

An exception was Remich, where a slight surplus of rainfall was measured.

In February, precipitation levels increased significantly. In Asselborn, a surplus of up to +47.4mm was recorded, representing an increase of 78% compared with the norm.

No major flooding was reported during the winter. Only a few very localised flooding incidents occurred along the Moselle in February.

Effects on agriculture

Winter crops have generally developed well, although some local damage caused by excess water was recorded in the autumn. Many fields have not yet been treated for weeds, and this work now needs to be carried out swiftly, according to the relevant services.

The situation for vegetable crops remains stable, although further rainfall will be needed to replenish water reserves. Vineyards are also facing a water deficit, meaning additional rain or snowfall would be necessary to restore sufficient soil moisture.
