Highest temperature in Munich on August 14?

Platform comparison

Market context

Munich Airport Station will record a highest temperature on 14 August 2026, measured in the Daily Observations table on Weather Underground rather than the Day High & Low summary. The Polymarket contract currently prices this outcome at 0% across all temperature bands, reflecting either extreme confidence in a specific range or minimal trading activity. Settlement hinges on the precise methodology: Weather Underground's granular observation data takes precedence over rounded daily summaries, a distinction that occasionally produces discrepancies worth monitoring when the market activates.

August temperatures at Munich Airport historically cluster between 20–27°C, with extremes reaching 30°C during heat waves. The station's 30-year average high for mid-August sits around 24°C. Recent summers have shown volatility: August 2022 saw temperatures exceed 30°C across Bavaria, whilst August 2023 remained cooler at 22–26°C. These precedents matter because the current 0% probability suggests traders are either awaiting price discovery or the market lacks sufficient liquidity to reflect genuine uncertainty about which temperature band will resolve.

European weather forecasting typically gains reliability 10–14 days before an event. Traders should monitor late July and early August 2026 for seasonal pattern indicators—whether the North Atlantic Oscillation favours warm continental air masses or cooler Atlantic systems. German meteorological services and Deutscher Wetterdienst announcements in early August will provide the most actionable signals. The settlement window closes at midday UTC on 14 August, creating a narrow window for final price adjustments once morning observations from Munich Airport are available on Wunderground.

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.
