Highest temperature in Munich on July 27?

Platform comparison

Market context

Munich's highest temperature on 27 July 2026 will be recorded at the airport weather station and resolved against historical data from Wunderground. The crowd currently assigns zero probability to any outcome, suggesting either incomplete market formation or uncertainty about which temperature bands are available for trading.

Munich's July climate sits firmly in the warm continental zone, with historical highs for late July typically ranging between 25°C and 28°C. The city's 30-year average maximum for late July hovers around 26–27°C, though extremes have reached into the low 30s during heat waves. The 0% implied probability across all outcomes indicates the market lacks sufficient liquidity or clarity on the resolution bands themselves, creating potential value for traders willing to anchor on climatological norms rather than panic-driven sentiment.

The relevant catalyst is the European summer weather pattern emerging in early July 2026. High-pressure systems dominating central Europe during late July typically drive temperatures upward, whilst Atlantic frontal systems can suppress them. Meteorological forecasts become reliable only 10–14 days before the settlement date, meaning traders should monitor mid-July weather models from services like ECMWF or DWD (Deutscher Wetterdienst) for signs of ridge or trough positioning over Bavaria. Recent summers have shown increased frequency of 30°C+ events in Munich during July, though 27 July specifically carries no exceptional historical signal. The settlement window closes at noon UTC, capturing only morning and early-afternoon readings.

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

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.
