Recent forecast consensus from sources including timeanddate and the Met Office points to a maximum near 21°C in Munich on August 21 under overcast skies with passing showers, aligning with the market's leading 32.5% implied probability for that outcome. Key variables include persistent cloud cover that limits daytime heating, the timing and intensity of light precipitation which can suppress peaks by 1–2°C, and steering patterns from regional high pressure that favor mild rather than extreme late-summer warmth. Model runs show modest uncertainty around exact cloud breaks or shower timing that could shift the daily maximum between 20–22°C, while historical August averages near 22–23°C provide context for why traders assign lower odds to 23°C or higher. Updated guidance expected in the next 24–48 hours will likely refine these probabilities.
