Official temperature readings from Munich stations confirm a daily maximum of 24°C on September 27, 2026, driven by clear skies, light easterly winds, and mild late-summer advection that allowed afternoon warming to that level. This aligns with DWD guidance projecting midday peaks near 21–23°C and independent model runs showing 23–25°C under similar synoptic patterns. Historical September averages near 17.8°C underscore the anomaly, yet the market-implied odds reflect real-time surface observations rather than forecasts. Minor adjustments remain possible only if final quality-controlled data from primary stations revise the peak downward due to microclimate effects or timing of the absolute high.
