The German weather service reported that June 2026 was among the warmest months recorded in the history of weather monitoring. With an average temperature of 19.5 degrees Celsius, it secured the second position nationally, surpassed only by June 2019, which recorded 19.8 degrees.
Compared to the historical reference period of 1961 to 1990, temperatures in June were 4.1 degrees higher. The third week of the month saw particularly intense heatwaves in the western regions, with temperatures exceeding 35 degrees Celsius on several days. Many regions broke monthly and all-time records for high temperatures. In Neißemünde-Coschen, Brandenburg, temperatures reached 41.7 degrees on Sunday, surpassing the all-time German record established the previous day.
In contrast to the heat, precipitation during June was below average and irregularly distributed. While areas along the Alps and in the far northwest of Germany received as much as 180 liters per square meter, other regions, such as the Middle and Upper Rhine, received significantly less. Overall, the first meteorological summer month saw approximately 66 liters per square meter of rainfall. This was drier than the long-term average, falling by roughly one-fifth compared to the 1961-1990 reference period (85 liters per square meter). Even when compared to the more recent and also drier reference period of 1991-2020 (76 liters per square meter), the month showed a deficit of approximately 13 percent.
Furthermore, sunshine hours were above average, totaling around 248 hours. This represents over 20 percent more than the long-term average (203 hours). Compared to the recent period of 1991-2020 (216 hours), there was still a positive deviation of 15 percent. This made June the fourth consecutive month to be significantly sunnier than the multi-year average.
