The market's overwhelming consensus on a 20°C high for Munich on October 3 stems from real-time observational data confirming this exact maximum at official stations, consistent with National Weather Service-equivalent forecasts under stable high-pressure conditions and light southerly flow. Early October climatology typically features average highs near 17°C, yet current model runs and surface observations aligned precisely on this mild anomaly without the warmer advection or clear-sky heating needed for higher readings. With the day largely concluded, resolution criteria based on verified daily maxima leave little room for deviation, though final post-processing or minor station adjustments could theoretically shift the recorded peak in edge cases.
