Highest temperature in Munich on August 1?

Platform comparison

Market context

Munich Airport’s **highest temperature on 1 August** will be a single-day weather outcome, and the market’s 1% YES price implies a very low chance of landing in the specified upper temperature band. That is notably conservative versus the broader August climate profile for Munich, where average highs are around 24°C to 25°C, with daily highs commonly in the low-to-mid 20s Celsius and occasional excursions higher in hot spells.[1][5][8][12]

For historical context, August in Munich is warm but not extreme on most days: climatology shows typical daily highs around 75°F/24°C, with records reaching 38°C in the city history and 92°F in some August datasets, so a very hot outcome is possible even if it is uncommon.[2][6][8] On a platform-comparison basis, the same weather outcome can look different across books: Polymarket-style markets quote an implied probability directly, while Betfair and Smarkets usually express the same view in decimal odds, so a 1% event corresponds to roughly 100.0 in decimal before commissions. Fee treatment also matters: exchange commissions at Betfair or Smarkets can materially reduce the net price for a winning trader, whereas the all-in cost on a prediction market is usually embedded in the trade price; access can differ too, with KYC and jurisdictional limits often tighter on exchange venues than on crypto-native platforms.

The key catalysts are the short-range forecast around Munich and any late-summer convective setup: the market resolves from the Munich Airport Station reading on Wunderground, and the settling window ends at 12:00 UTC, so the relevant move is the day’s *maximum* temperature rather than the midday snapshot.[20] Traders should watch the updated forecast for upper-air warmth, sunshine, and thunderstorm timing, because a strong afternoon heating pattern can lift the daily high even if showers arrive later; Munich’s August climate also carries meaningful day-to-day variability, with highs often easing back after the first week of the month.[2][12][14]

Methodology

We read Highest temperature in Munich on August 1? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
