Forecast models from sources including ECMWF and DWD indicate Munich's overnight low on September 14 will likely fall between 12–15°C amid increasing cloud cover, light rain, and moderate northwest winds associated with a passing frontal system. These conditions suppress radiative cooling compared to clearer nights, supporting temperatures above the long-term September average low of roughly 10°C while limiting upside potential from daytime warmth. Ensemble spreads highlight sensitivity to exact precipitation timing and wind shifts, which could nudge the minimum a degree or two in either direction. Market-implied odds remain tightly clustered because resolution hinges on the precise recorded minimum at official stations, with fresh model runs expected overnight to refine the outlook.
