Multiple weather models and observational updates, including GFS data and station guidance, converged on a daily maximum of 24°C in Munich on September 20 under mostly cloudy skies, light westerly winds, and minimal precipitation. This value sits above the 1991–2020 climatological average high of 19.1°C yet aligns with current mild autumn conditions and recent model runs showing stable steering patterns. Trader consensus at near-100% implied probability for 24°C reflects this agreement across sources, with official daily maximums typically derived from calibrated surface observations. A realistic shift would require an unforecasted late-day surge or station-specific microclimate deviation exceeding normal measurement uncertainty.
