Highest temperature in Munich on August 1?

Platform comparison

Market context

Munich Airport’s highest temperature on 1 August will be set by how warm the afternoon gets at the official station, not by the citywide average. The contract’s 1% yes price implies the crowd sees an extreme outcome in the upper tail, while broad August climate data point to much more ordinary warmth: forecast monthly highs are centred around the mid-20s Celsius, and climatology places Munich’s August average high near 24–25°C, with typical warm-day peaks around 31–32°C rather than the high 30s.[1][6][16]

That framing matters because Munich has a genuine but infrequent heat-spike history. Records in the region show the city has reached 35–37°C in past August heatwaves, with the Munich historical maximum of 37.0°C logged in August 2003 and additional late-summer extremes above 34°C appearing in the local record.[5][3][8] Against that backdrop, a 1% market price is not far from a “once-in-many-years” type event, and it sits well below the sort of probability you would expect for a standard warm August day; no sportsbook line is available in the supplied data, so the main comparison point is that the market is pricing a very sharp tail rather than a normal seasonal distribution.[4][10]

For traders, the key catalysts are the synoptic setup over southern Germany, cloud cover and convective risk, because late-day thunderstorms can cap the daytime maximum even when the morning starts hot.[10][16] The main dependency is the Munich Airport Station reading itself on Wunderground, so forecasts for Munich city centre are only a proxy; temperature outcomes can differ materially between the airport and the urban core, especially if the day turns breezy or stormy.[1]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
