2020  was with 11.07 °C the second warmest year since records began at our experimental station in Berge near Nauen in Havelland. The warmest year so far was 2019, the last 3 years were the warmest since 1954. The long-term average (1991 - 2020) is now 9.96 C°. The trend towards higher temperatures has been reinforced by this warm year. Statistically, it is getting warmer by almost 0.04 °C every year. The trend of the last 67 years can best be described as "linear" (R²=0.52). The precipitation total of 434 mm in 2020 is significantly below the long-term average of 526 mm. Crops lacked water especially in April and May, while most crops benefited from the high precipitation in June. The annual amount of precipitation did not change statistically during the observation period (since 1951): We now had 3 dry years in a row, but before that we always had above-average precipitation.

The data come from the German Weather Service, which operates a weather station at our experimental station in Berge.
