Highest temperature in Munich on August 17?

Platform comparison

Market context

Munich Airport is set for a modest, rain-affected day rather than an extreme temperature print, with the main forecast clusters around the low 20s Celsius and a decent chance of showers or thunderstorms. That leaves the most likely settlement bands concentrated around 21°C to 23°C, which is consistent with the market’s 0% yes-price on any far-higher outcome and with the broader view that cloud cover will cap the daytime peak.[1][2][3]

Historically, Munich’s August highs can vary sharply, but a wet, convective setup usually trims the upper end of the distribution relative to hot, settled spells. Comparable forecasts for 17 August point to 21°C or 22°C in several models and consumer weather services, while the exchange contract itself has clustered around the low-20s outcomes rather than the upper bands, leaving little room for a surprise unless the morning clears more than expected.[1][2][3]

For traders, the key catalysts are the latest station observations at Munich Airport, any update to the short-range European and German weather guidance, and whether showers arrive earlier or later than forecast, because that affects the day’s maximum before the 12:00 UTC settlement cut-off. The contract note also matters: settlement is based on Weather Underground’s Daily Observations table, so a brief midday spike there will count even if the summary high-low section differs.[2][3]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
