Forecast models from sources including the German Weather Service and GFS consensus indicate a high of 23–24°C for Munich on September 26 under clear to mostly sunny skies, light northeasterly winds, and minimal cloud cover that will promote strong daytime solar heating. This setup, supported by high surface pressure near 1023 hPa and dew points in the mid-single digits Celsius, favors temperatures well above the 1991–2020 September 26 average high of 18°C. Recent model runs show tight agreement with little spread, limiting upside risk for 25°C or higher while keeping 22°C or below as lower-probability outliers unless unexpected overnight cloud increases occur. The market's heavy weighting toward 23°C reflects this stable, above-normal pattern with resolution hinging on official DWD or equivalent maximum readings.
