Current forecast models from the German Weather Service (DWD) and GFS indicate clear skies and light southerly winds over Munich on September 26, 2026, promoting radiative cooling overnight with minimum temperatures expected near 6–8°C. This aligns with late-September climatology where average lows hover around 8.9°C, though model consensus shows limited spread and low precipitation risk that could otherwise moderate cooling. Trader sentiment remains split between the 47.5% implied probability for a minimum of 10°C or higher and 43.5% for 0°C or below because small shifts in cloud cover, wind speed, or boundary-layer mixing could push the overnight low across those thresholds, while intermediate outcomes like 2°C or 4°C reflect narrower uncertainty bands. Official DWD station readings will resolve the market.
