The market's overwhelming consensus on 28°C as Munich's highest temperature for September 7 stems from verified observational data and high-resolution forecast models confirming a daytime peak under stable high-pressure conditions with light southerly flow and minimal cloud cover. This value exceeds the 1991–2020 seasonal average high of 21°C, driven by enhanced solar heating and warm advection typical of early September patterns. European models showed tight agreement on maximums near this threshold, with surface observations from stations like Munich Airport aligning closely. Scenarios that could realistically alter resolution remain limited to minor station-specific discrepancies or final quality-control adjustments by the Deutscher Wetterdienst, though current convergence makes significant revisions improbable.
