Highest temperature in Munich on August 6?

Platform comparison

Market context

Polymarket prices this contract at **0% YES** today, so the market is effectively assuming the Munich Airport Station will not print a top temperature in the relevant bucket on 6 August. The event is resolved from the *highest recorded temperature* for the day at Munich Airport Station on Wunderground, and settlement is tied to the conditional-token outcome on Polygon with USDC collateral, so the practical question is whether the observed peak lands inside the market’s listed range before the window closes.[5][13]

That zero-implied price is striking against Munich’s August baseline. Seasonal references point to average daytime highs around the mid-20s Celsius, with August norms commonly cited near 22-25°C and occasional warmer days into the upper 20s or low 30s; one August 2026 outlook shows highs mostly in the low-to-mid 20s Celsius, while broader monthly climatology suggests highs typically cluster around 70-76°F and rarely exceed the high 80s Fahrenheit.[1][4][6][18] In other words, a 0% quote implies the market sees the current setup as either mispriced or dependent on a very specific range that is not being assigned any probability by traders.

For a hands-on Polymarket user, the main catalysts are the live Munich Airport observations and any short-notice forecast swings in cloud cover, rain, or wind, because those are what shift the intraday maximum, not the morning reading. Current forecast feeds are mixed but not extreme, with some services showing around 20-24°C and others pointing to a warmer afternoon near 27-29°C, which is still broadly consistent with August norms rather than an obvious spike setup.[2][3][16] With resolution sourced from Wunderground history for EDDM, traders will also watch whether the airport station records a brief late-afternoon high before the settlement cutoff rather than relying on citywide Munich weather alone.[5]

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.
