A markedly warmer September with cool nights saw wine growers rewarded with a mature harvest of grapes of good quality and normal quantity, but autumn overall lacked rain.

The AgriMeteo weather service--a department within the agriculture ministry--on 1 December published its weather bulletin from 1 September to 30 November 2021.

Autumn on average was colder and dryer than in previous years, the report said, mainly because of October and November, which in its final days saw a cold snap resulting in the first flurry of snow falling on the Oesling region (6.6cm in Reuler).

October was marked by storm Aurore hitting Luxembourg on the 21st with gusts of wind between 70 and 90km/h, with a maximum of 98km/h recorded in Eschdorf. Rainfall was below average at 54.6 litres/m2 compared to a 1991-2020 average of 76.6 litres.

November rainfall of 41.6 litres per square metre compared to a 72.1 average.

However, September provided wine growers with good news as temperatures beat annual averages with notable peaks at the start and end of the month. The mild weather in the Moselle region allowed the grapes to develop in ideal conditions, just in time for the start of the harvest on 27 September.

Despite a positive September, the report points to a continued deterioration of normal weather pattern, highlighted by the devastating floods of July. This autumn saw precipitation reach only between 65 to 85% of the seasonal averages when compared to the period between 1991 and 2020.

A full overview of the year’s weather isn’t yet available, but 2020 was the hottest year on record in Luxembourg and the seventh year with too little rain in a row.
