Highest temperature in Munich on August 19?

Platform comparison

Market context

Munich's daily high temperature on 19 August 2026 will be measured at Munich Airport Station and resolved against Weather Underground's Daily Observations table rather than its summary figures—a distinction that matters when platforms diverge on data interpretation. The current 0% implied probability suggests traders view this as either a placeholder market awaiting calibration or expect the settlement window's noon cutoff to create ambiguity around intraday peak readings.

August highs in Munich typically range between 24–28°C, with extremes occasionally reaching 30°C during heat waves. Historical August records show the city experiences warm but not exceptional conditions compared to southern German regions; the 2003 European heat wave and 2022's late-summer spike provide reference points for how far temperatures can deviate from seasonal norms. Traders should note that Weather Underground's Daily Observations feed occasionally lags behind real-time reporting, and discrepancies between airport-station readings and city-centre measurements have historically created settlement disputes on weather markets across Polymarket, Kalshi, and Betfair.

The key variable is whether a significant heat event materialises in mid-August 2026. German meteorological forecasts typically become reliable only 10–14 days ahead; traders should monitor Deutsche Welle and Deutscher Wetterdienst announcements from early August for heat-wave warnings. The noon settlement cutoff introduces a technical risk: if temperatures peak in late afternoon, the recorded high may reflect only partial daily heating, potentially shifting outcomes across temperature bands. Kalshi's stricter data-source verification and Smarkets' longer settlement windows offer different risk profiles compared to Polymarket's faster resolution mechanics on European weather contracts.
