Heavy snow, hard frosts
The first two weeks of the Easter month were fickle and varied bringing stormy episodes, heavy snow in some regions, hard night frosts and the first days of summer temperatures. Then, during the second ten days of the month, dry and stable weather prevailed. This was followed by a sunny Easter period and signs of the flora and fauna continuing to awake after winter. A small depression over the south at the end of the month was a gradual indication of the coming period of heavy rain and thunderstorms.
1.2°C cooler than the valid climate mean
Compared to the currently applicable 1991–2020 reference period, the April 2022 was 1.2 degrees COOLER than the mean. But why does the DWD claim in its press release to the media that April was all in all “somewhat too warm”?
Using an ancient, cooler reference period
To do this the German DWD weather agency neither used the now expired 1981 – 2010 reference period nor the the 1971-2000 period to make the comparison, but rather it went deep in the archives to the 1961 – 1990 period. Only this way were they able to finally say April, 2022, was 0.4°C warmer than the mean. These are the tricks the DWD pulls in order to fabricate a press release to call an otherwise cool month a “warm” one.
During the second ten days of the month, the figures settled around the average for April. The lowest temperature nationwide was measured on April 4th in Meßstetten on the Swabian Alb (-14.6°C). The highest monthly temperature of 26.0 °C was recorded on April 13th in Wolfach 60 km further west in the central part of the Black Forest.
“Record depths of snow”
With around 55 liters per square meter (l/m²), precipitation in April was just under 5 per cent less than the average precipitation of 58 l/m² recorded during the ancient 1961–1990 reference period. Low pressure brought plenty of precipitation during the first ten days of the month and even saw record depths of snow in the central area.
Sunny coastal regions and cloudy low mountain ranges
At 195 hours, the sunshine duration in April was around 20 per cent higher than the average figure of 154 hours for the ancient 1961–1990 period. Compared to 1991–2020, the deviation was 5 per cent higher than normal. After a number of dull days, the sunshine after Easter made up for lost ground. Coastal areas were particularly sunny in April, recording over 200 hours of sunshine. The Baltic Sea coast even received over 250 hours whereas the central low mountains saw much less with 150 hours.
All the monthly values stated in this press release are provisional figures and the data used for the last two days of the month are based on forecasts.
