Highest temperature in Munich on August 15?

Platform comparison

Market context

Munich's highest temperature on 15 August 2026 will be recorded at Munich Airport Station and measured against discrete temperature bands in Celsius. The market resolves using Weather Underground's Daily Observations table rather than their summary section, a distinction that matters when intraday peaks diverge from reported highs. Settlement occurs at 12:00 UTC on the day itself, meaning traders must assess forecasts without benefit of the full calendar day's outcome.

August temperatures in Munich historically cluster between 24–28°C, with extremes occasionally reaching 30°C during heat waves. The 0% crowd probability suggests either the market is pricing an implausibly narrow range or reflects low liquidity and sparse trader participation. Comparable weather markets on Polymarket and Kalshi show divergent approaches: Polymarket typically offers tighter decimal odds on weather outcomes, whilst Kalshi's regulatory framework in the US sometimes restricts European weather markets entirely. Betfair and Smarkets, conversely, maintain broader European coverage but charge different commission structures—Betfair's 5% exchange fee versus Smarkets' variable maker/taker model—which affects effective implied probabilities across identical underlying events.

Traders should monitor European weather forecasting updates from mid-July onwards, particularly any heat dome formation or Atlantic pressure systems affecting Central Europe. The Deutsche Wetterdienst (DWD) publishes extended forecasts that often precede broader market repricing. Seasonal climate patterns and any unusual atmospheric conditions in the weeks preceding mid-August will shape whether the eventual high falls within cooler or warmer bands, making early-summer meteorological data a key dependency for position-building.
