Luxembourg’s national weather service, Meteolux, has announced that January 2025 was the third wettest January in the country since records began in 1947. The month saw exceptionally high rainfall, with the first and last ten days being particularly wet.
A total of over 148 liters of rain per square meter was recorded, exceeding the climatological average of 72.0 l/m² for the past 30 years by 106%. One of the most intense rainfall events occurred on Sunday, 5 January, when nearly 25 litres of rain fell per square metre in a single day.
This record-breaking rainfall makes January 2025 the third wettest January since measurements began at Findel Airport in 1947. The absolute record remains January 1995, with 197.1 l/m², followed by January 1988, with 195.5 l/m². The recently concluded month now ranks third on the list of the wettest Januarys in the post-war period.
Meteolux attributes the unusual rainfall to strong negative atmospheric pressure anomalies over the North Atlantic and over Western Europe, which created low-pressure conditions in the region.
Meteorologists also suggest that the exceptional rainfall is “probably” linked to climate change, though further studies are needed to confirm this connection. Scientists have already established that global warming, particularly the heating of oceans, increases atmospheric moisture, leading to heavier precipitation and more extreme weather events.
