Recent European model runs and official guidance from agencies like the DWD and Met Office point to a cooling trend over southern Germany, with Munich's August 21 high most likely reaching 21–22°C amid passing showers and variable cloud cover that limit daytime heating. Key variables include the timing and intensity of thundery showers, which can suppress peaks by several degrees, along with wind patterns and boundary-layer moisture that influence how much solar radiation reaches the surface. Historical August averages near 22–23°C provide context, yet short-term fluctuations in these factors create the broad probability distribution seen in trader positioning, with outcomes below 20°C or above 23°C remaining possible if showers arrive earlier or later than expected. New model updates over the next 48 hours will likely refine these odds ahead of market resolution.
