Persistent cloud cover, widespread rain, and moderate westerly winds are keeping overnight cooling limited in Munich, with multiple forecast models converging on a minimum between 11–13 °C. High humidity and a steady flow of maritime air from the Atlantic have prevented stronger radiational cooling that would otherwise push readings toward the lower end of the historical September range. Official guidance from European models shows the coldest hour likely occurring just before dawn, with slight differences in timing of showers and wind gusts creating the tight clustering of market-implied odds around 11 °C, 12 °C, and 13 °C. Updated model runs later today will refine whether the low settles near the average 11 °C baseline or edges higher under lingering overcast.
