Highest temperature in Munich on August 14?

Platform comparison

Market context

Munich Airport's meteorological station will record the daily maximum temperature on 14 August 2026, with settlement determined by the highest reading in Weather Underground's Daily Observations table rather than their summary figures. The current market pricing reflects 0% probability across all temperature bands, suggesting traders are either absent or awaiting clearer atmospheric forecasting data as the date approaches. On Polygon, this conditional token contract settles in USDC against whichever temperature bracket captures the actual high, with resolution contingent on Weather Underground's primary data source.

August temperatures at Munich Airport historically range between 24–28°C, with extremes occasionally reaching 30°C during heat waves. The 14th falls mid-summer when continental European pressure systems dominate; comparable years show variability driven by Atlantic frontal systems or Saharan air masses pushing northward. In August 2023, Munich recorded 28.2°C on the 14th; in 2022, the same date peaked at 25.1°C. This historical spread—spanning roughly 3°C—illustrates why traders should monitor European weather models from late July onwards rather than relying on current pricing.

Catalysts include the German Meteorological Service (Deutscher Wetterdienst) forecasts, typically issued five to ten days ahead with meaningful refinement by early August. Broader climate patterns—the North Atlantic Oscillation phase and Mediterranean sea-surface temperatures—influence whether August 2026 trends toward cooler Atlantic influence or warmer continental conditions. Traders should track whether European heat-dome forecasts emerge in early August, as such announcements historically shift market pricing substantially on weather contracts with narrow settlement windows.

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.
