Germany’s national weather service DWD has released preliminary data for Germany’s average temperature and precipitation for May 2023. This month is temperature normal using the 1991-period climate averages. 2020 and drier than usual.
Those hoping to be compensated after cool April only get what they deserve in times of May 2023 – at times when it’s warm like summer, but for the most part, very cool days make up the difference. dominance.
A cool start to the month was followed by a cool period, and on the last Tuesday of the month the “Little Ice Saints” found themselves having chilly nights despite plenty of sunshine. Unfortunately, the dreaded spring and early summer droughts have re-emerged, especially in northeastern Germany, reducing crop prospects, although much less severely than in 2022. .
As a result, May 2023 is not entirely positive – but in the long run, neither temperature nor May precipitation show any worrisome trends.
The figure above shows that despite the increase in CO2 concentrations, the trend of average May temperatures has not increased since 1986.
Rainfall in May 2023 – barely enough
With around 44 mm of rain, just two-thirds of the average for the period 1991 to 2020, this May is not one of the driest months since 1881.
Unfortunately, the well-known rule “When May is warm and dry, all growth stops” still applies, even when CO₂ levels rise sharply, helping plants to survive better in climates. drought period.
Long-term rainfall trends are nothing to worry about
The northeastern region of Germany, already suffering from drought, is also at a severe disadvantage this May; from about Elbe to the northeast, falls below 20 mm most of the time; after 2018, 19, 20 and 22, the next crop will occur. In Weimar, the usual early summer drought begins quite late at this time; in the last ten days of May. The situation is somewhat better in the center of the country and much better in the south-west of Germany.
However, a look at the long-term development of May precipitation reveals nothing to worry about:
