Highest temperature in Munich on August 20?

Platform comparison

Market context

The crowd is pricing this market at 0% probability, implying near-certainty that Munich's peak temperature on 20 August 2026 will fall below whatever threshold defines the lowest resolution bracket. This reflects the consensus view that summer heat in Bavaria, whilst notable, rarely reaches extremes. Munich's August average high sits around 24°C, with temperatures exceeding 30°C occurring in roughly one-third of years. The 0% reading suggests traders expect the outcome to land in a lower temperature band entirely, leaving potential value if summer 2026 develops warmer-than-typical conditions across central Europe.

Historical August records for Munich Airport show a maximum of 37.3°C, set in 2015 during an exceptional European heatwave. More typical hot days cluster between 28–32°C. The current probability structure implies the market's brackets are calibrated to capture outcomes well below that historical ceiling, making the favourite band one that encompasses typical or slightly-above-typical August conditions. Traders should note that European summer forecasting remains uncertain two years ahead, though climate data suggests no systematic shift toward cooler Augusts in the region.

The settlement mechanism's reliance on Weather Underground's Daily Observations table rather than summary highs introduces a technical dependency worth monitoring. Any discrepancy between reported figures could affect marginal cases. Traders tracking this market should watch European weather pattern development in summer 2026, particularly any signals of high-pressure systems anchoring over central Europe—the primary driver of Munich's occasional extreme heat days.

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.
