Recent forecasts indicate a frontal system will bring increased cloud cover, showers, and northwesterly flow to Munich on October 2, limiting daytime heating after late-September highs near 24–25 °C. Official guidance and ensemble runs cluster the daily maximum around 18 °C, with the precise value hinging on the timing and intensity of precipitation, boundary-layer mixing, and solar insolation through broken cloud decks. Thicker or earlier rain would cap temperatures near 18 °C by suppressing surface warming and enhancing evaporative cooling, while delayed or lighter showers could allow brief clearing and push readings to 19–20 °C. Current model consensus and observed pressure rises support the tight 18–20 °C range reflected in market pricing, with resolution likely determined by the 12–18 UTC window when peak insolation typically occurs.
