In early September 2026, Bavaria experienced a shift in weather patterns following a summer noted as one of the hottest on record. Initially, meteorologists predicted a return to warm conditions, with air from the western Mediterranean potentially raising temperatures to 35 degrees Celsius in some southwestern regions.

By mid-September, the region saw a significant temperature drop from 30 degrees Celsius to below 20 degrees Celsius. The German Meteorological Service (DWD) forecasted fluctuating conditions involving alternating sun, clouds, and rain. While nighttime temperatures were expected to fall into the single digits, there were indications of a potential ‘Indian summer’ (Altweibersommer) developing toward the middle of the month, coinciding with the start of Oktoberfest.
