Current forecasts from the German Weather Service (DWD) and supporting models point to an overnight low near 6–10°C on September 12 under building high pressure, clear skies, and light winds that promote strong radiative cooling after sunset. This setup favors minimum temperatures in the single digits Celsius, consistent with the historical average low of 10.5°C for the date while allowing for cooler outcomes if dew points drop further. Model consensus remains stable in the short term, though small shifts in cloud cover or wind could raise readings toward 11–12°C. Traders appear to price in some upside uncertainty around the exact minimum, reflected in elevated probabilities for 14°C or higher alongside clustered interest near 8–10°C. Updated model runs and DWD briefings ahead of the night will provide the next key data points for resolution.
