Highest temperature in Munich on August 1?

Platform comparison

Market context

Munich Airport’s highest temperature on 1 August will be set by a single-day daytime peak rather than the whole month’s average, and the market settles on the Wunderground high for the airport station. August in Munich is normally warm but not extreme: long-run climate pages put typical highs around 24°C to 25°C, with daily highs near 23°C to 26°C in southern Germany and monthly averages around 24°C in Munich.[5][8][12] That makes the current 1% “YES” price consistent with a view that a very specific temperature band is unlikely to be hit, although the exact band in this market matters more than the broad August average.

Historically, Munich’s August maxima can vary materially year to year, with record highs in the high 30s Celsius and ordinary August daily highs clustering in the mid-20s Celsius.[6][8] Comparable climate data for Munich Airport is not included in the search results, so the best analogue is the city-wide pattern: the market should be read as a tail-event question, not a forecast of whether August will feel warm. On Polymarket, the quoted price is an implied probability; on Kalshi it is usually shown as the same concept but with exchange-style contracts and a clearer fee line, while Betfair and Smarkets present price and commission differently, so identical views can imply different net outcomes after costs.

The main catalyst is the weather itself: sunny, warm afternoons raise the chance of a higher terminal temperature, while cloud cover or showers can cap the day’s peak. The market cannot resolve until the end of the settlement window, so traders should watch the Munich Airport forecast, any heat surge over central Europe, and whether convective storms develop later in the day; August can bring late-day thunderstorms in southern Germany.[12] Platform mechanics matter here too: Betfair and Smarkets may be unavailable to some US-facing users, while Kalshi and Polymarket differ in KYC reach and whether the displayed market price is before or after fees, which can change the practical breakeven on a low-probability contract.
