Highest temperature in Munich on August 16?

Platform comparison

Market context

Munich's weather on 16 August 2026 will determine which temperature band captures the day's peak, measured at Munich Airport Station and sourced from Weather Underground's Daily Observations table. The market currently prices a YES outcome—temperatures reaching the upper threshold of the specified range—at 2%, implying traders expect a cooler or moderate day relative to the range boundaries. This contract settles in USDC on Polygon, with conditional tokens reflecting the binary outcome once Wunderground data is finalised on 16 August at 12:00 UTC.

August temperatures in Munich historically cluster between 20–28°C, with extremes rarely exceeding 30°C at the airport station. The 2% probability reflects scepticism about reaching the market's upper temperature threshold; comparable August days over the past decade show that peak temperatures in the high 20s are routine, whilst sustained heat pushing toward 32°C or beyond occurs in roughly one in five years. The 2023 summer saw Munich peak at 32.2°C on 9 August, providing a recent benchmark for what constitutes an unusually warm day in the region.

Traders monitoring this contract should track European weather forecasts from mid-August onwards, particularly high-pressure systems developing over central Europe. The German Meteorological Service (Deutscher Wetterdienst) publishes extended forecasts approximately 10 days ahead; any signals of an Iberian heat dome extending northward would shift market pricing materially. Additionally, the specific resolution source—Daily Observations rather than the Day High & Low summary—creates a technical dependency; traders should verify Wunderground's historical consistency in reporting Munich Airport data to assess settlement risk.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
