Highest temperature in Munich on August 16?

Platform comparison

Market context

Munich's highest temperature on 16 August 2026 will be recorded at Munich Airport Station and resolved against Weather Underground's Daily Observations table. The crowd has priced this at 1% implied probability, suggesting the market is pricing in an exceptionally hot day—likely above 35°C or into a higher temperature bracket—as a tail-risk outcome.

August in Munich typically sees highs between 24–27°C, with extreme heat days (above 32°C) occurring roughly once every few years during the month. The city's 30-year average for mid-August peaks around 25°C. Historical precedent shows that temperatures exceeding 35°C in Munich during August are rare but not unprecedented; the region experienced a heat wave in summer 2022 with several days above 35°C. At 1% implied probability, the market is essentially betting against a significant departure from seasonal norms, which aligns with climatological baselines for this specific date and location.

Traders should monitor European weather forecasting updates in the weeks leading to mid-August 2026, particularly from Deutscher Wetterdienst (DWD), Germany's national meteorological service. High-pressure systems tracking northward from southern Europe or Saharan air masses occasionally push temperatures sharply upward across Bavaria. The resolution hinges on Weather Underground's Munich Airport Station readings—a specific measurement point that may differ slightly from city-centre observations. Any forecast consensus showing anomalous heat building across central Europe in early-to-mid August would represent the primary catalyst for repricing this market away from its current tail-risk valuation.
