A warm and regionally also very dry "rocking summer"



Offenbach, August 31, 2020 - The summer of 2020 was often changeable. At times stable weather conditions only brought midsummer warmth for a short time. It wasn't until August that midsummer turned to full speed. In tropical air, temperatures rose to 30 degrees Celsius (° C) and more over several days. Heavy rain thunderstorms erupted here and there, but in some places it remained very dry. The bottom line was that summer 2020 was too warm and a little too dry with balanced sunshine. This is what the German Weather Service (DWD) reports after initial evaluations of the results of its around 2,000 measuring stations.

In June and July "rocking summer" with fluctuating temperatures
At 18.2 ° C, the summer of 2020 was 1.9 degrees above the mean of the internationally valid reference period 1961 to 1990. Compared to the warmer reference period 1981 to 2010, the positive deviation was 1.1 degrees. In the months of June and July, stable midsummer phases were a rarity. Cool and warm weather phases alternated, so that the first summer months were more like a "rocking summer". Only in August did a heat wave lasting several days with temperatures of over 35 ° C lead to high to extreme heat loads across the country. The highest temperature in Germany was on August 9th. measured at 38.6 ° C in Trier-Petrisberg. The lowest early temperatures were recorded by the DWD at the beginning of June. On 1.6. The Oberharz station on Brocken-Stiege reported a fresh 0.5 ° C.

Heavy rain, floods, floods and regionally still very dry
With around 230 liters per square meter (l / m²) of precipitation in the nationwide mean, the summer of 2020 fell short of its target (239 l / m²) only slightly. Heavy rainfall with flooding and persistent drought were often close together. In some regions, such as the Uckermark, the Leipzig lowland bay, the Saarland and along the Rhine, 70 to 100 l / m² fell less than half of the typical rainfall there. At the same time, there were continuous rainfalls, such as at the beginning of August with up to 150 l / m² in 24 hours in Upper Bavaria, which also brought floods. A total of over 700 l / m² was measured in the Alps over the summer, ten times as much as in the dry regions of Germany.

Balanced sunshine balance
At around 675 hours, the duration of sunshine in summer exceeded its target of 614 hours by around 10 percent. The coastal regions recorded over 700 hours of sunshine. In the western low mountain ranges, however, the DWD only measured around 500 hours.

Bavaria: The Free State was the second coolest region in the summer of 2020 with an average temperature of 17.5 ° C (15.8 ° C).

In Upper Bavaria, 100 to 150 l / m² fell within 24 hours at the beginning of August. On August 3rd, Aschau-Innerkoy reported the highest daily precipitation with 152.4 l / m².
