Highest temperature in Munich on August 11?

Platform comparison

Market context

Munich's highest temperature on 11 August 2026 will be measured at Munich Airport Station and recorded in Weather Underground's Daily Observations table, with resolution based on that primary source rather than any summary figures. The current 0% crowd probability suggests traders are either absent from this market or treating it as a placeholder pending more substantive activity as the date approaches.

Historical August temperatures in Munich typically range between 24–28°C, though peaks above 30°C occur roughly once every three to five years during heat waves. The 2023 European summer saw Munich reach 34.6°C in mid-August, providing a recent benchmark for extreme scenarios. Traders evaluating this market should note that August 2026 forecasts remain unavailable; seasonal patterns and climate data from comparable years offer the only current reference points. Kalshi and Betfair's decimal-odds formats may display differently than Polymarket's implied probability representation, potentially affecting how traders perceive tail-risk ranges at the extreme temperature brackets.

Catalysts include the European summer weather pattern forecast, typically published by national meteorological services in late July 2026. Any significant heat dome or Atlantic blocking pattern would shift probabilities toward higher temperature ranges. The specific reliance on Weather Underground's Daily Observations table—rather than official German meteorological records—creates a minor technical dependency; traders should verify that station remains operational and reporting throughout August. Settlement occurs at 12:00 UTC on 11 August, meaning morning temperatures will not factor into the final resolution.
