Highest temperature in Munich on August 10?

Platform comparison

Market context

Munich’s highest temperature on 10 August will be set by the maximum reading at Munich Airport Station in Weather Underground’s Daily Observations table, so traders should focus on the intra-day peak rather than the headline “Day High & Low” summary. For this market, the current crowd-implied **0% YES** on Polymarket is a probability signal, whereas Kalshi and Betfair-style books usually express the same view as decimal odds, making the same weather outlook look different even before fees; Smarkets’ exchange model also tends to be easier to compare on raw price, but not on net cost after commission. Historical August weather in Munich suggests that a mid-20s Celsius outcome is the normal centre of gravity, with climatology putting August averages around 24°C and long-run record highs in the high 30s. [3][16][2]

Comparable August cases show why a zero-priced “YES” can still be misleading if a hot spell develops late in the day. Munich’s August record high is 37.0°C, reached on 13 August 2003, while the city’s typical August maximum is around 24°C, so the market only needs one sufficiently warm afternoon reading to move into a higher band. That said, Weather Underground’s historical pages and standard forecast products for Munich have recently pointed to highs around the low 30s Fahrenheit-equivalent? No — in Celsius terms, current forecasts for early August have been in the low 30s Celsius on some days, which means the settlement band is sensitive to cloud cover, rain timing and the exact airport observation. [2][4][6]

For traders, the main catalysts are the day’s forecast evolution, any rain showers or thunderstorm timing, and whether the Munich Airport observation records a brief afternoon spike before cooling sets in. The latest Munich weather history page shows morning readings around 20°C and sunny conditions, which leaves room for a warmer midday peak if insolation strengthens. Platform structure matters here: Polymarket’s implied probability can jump discretely as orders hit the book, Kalshi and Betfair quote in price terms, and Smarkets charges commission on winnings rather than embedding it in the spread, so the same temperature outlook can trade at different apparent “fair values” across venues. KYC access also differs, with US-facing access on Kalshi narrower than on exchange-style books available in more jurisdictions. [1][3][4]
