Highest temperature in Munich on July 27?

Platform comparison

Market context

On 27 July 2026, the highest temperature recorded at Munich Airport Station will fall into one of several defined ranges. The settlement mechanism relies on historical weather data from Wunderground, making this a straightforward factual resolution tied to a single meteorological reading rather than interpretation or consensus forecasting.

Munich's summer temperatures typically peak in late July, with historical records showing daily highs between 24–28°C during this period. The 0% crowd probability suggests traders are either absent from this specific market or awaiting clearer seasonal forecasts closer to the date. Comparable European airport weather markets on Kalshi and Polymarket have shown that temperature-range contracts often trade with wider spreads than binary yes/no markets, partly because the outcome space is fragmented across multiple resolution buckets. Betfair's decimal odds format can obscure the true implied probability across ranges, whereas Polymarket's AMM structure typically displays probabilities more transparently—a distinction worth noting when comparing order-book depth across platforms.

Traders should monitor the European summer weather pattern forecast from mid-July onwards, particularly any high-pressure systems or heat waves predicted for Bavaria. The German Meteorological Service (Deutscher Wetterdienst) publishes extended forecasts roughly two weeks ahead. Fee structures differ materially here: Kalshi charges a flat 5% settlement fee, whilst Polymarket's Polygon-based infrastructure carries lower transaction costs but requires USDC holdings. Smarkets' commission model sits between these two, making position sizing calculations platform-dependent for identical temperature outcomes.
