Germany and Central Europe are transitioning into autumn, characterized by unseasonably warm, late-summer conditions. In Germany, a strong blocking high-pressure system has kept Atlantic low-pressure systems at bay, allowing temperatures to reach between 24 and 25 degrees Celsius in some regions. In North Rhine-Westphalia, Lippstadt recorded 30.9 degrees on September 30, marking the latest hot day on record for the region. This contributed to a record 23 hot days in 2026 for the area, significantly exceeding the long-term average of eight. In Austria, the seasonal transition has been marked by extreme warmth; September 2026 concluded as the 14th warmest September in 260 years of recording. In Vienna, September was exceptionally warm and dry, with temperatures 2.1 degrees above the long-term average and precipitation 30 percent below normal. Geosphere Austria reported record-breaking heat days, with 171 stations setting new annual records. In the Salzkammergut region, temperatures frequently exceeded 30 degrees Celsius. Despite recent rainfall, a significant precipitation deficit remains, continuing a trend of drought following an extremely dry summer. This prolonged dry period has left the Rhine river at critically low levels, which is hindering shipping. In Czechia, the “Indian summer” (babí léto) is expected to continue through the first week of October with temperatures reaching 25 degrees Celsius, though high winds have triggered warnings in northern regions. Forecasters predict a significant cooling trend toward the end of October, with daytime highs potentially dropping to 12 degrees. As October progresses, weather patterns are showing regional volatility. While some German areas, such as Hessen, face a cold start to the month with heavy rain and thunderstorms caused by storm ‘Eva’, meteorologists predict a ‘golden October’ with sunny intervals and temperatures between 20 and 25 degrees Celsius. In Italy, an Omega block weather pattern is expected to bring stable, sunny, and warm conditions—often referred to as an ‘Ottobrata’—until at least October 6, with temperatures potentially reaching 29 degrees Celsius.
