Highest temperature in Munich on July 1?

Platform comparison

Market context

The underlying event is the highest temperature recorded at Munich Airport on 1 July 2026, a date that historically sits within Germany’s peak summer heat window. Current crowd-implied probability of 0% for the “YES” outcome suggests traders expect the temperature to fall outside the defined range, likely because recent forecasts indicate thundery showers and cooler conditions rather than extreme heat. Today’s observed temperature at München-Flughafen is just 26°F (−3°C), with 97% humidity and rising pressure, pointing to unsettled weather rather than a heat spike [2].

Historically, Munich in July sees daily highs averaging 75°F (24°C), rarely exceeding 87°F (31°C), though extreme heatwaves have pushed temperatures to 38°C in the past, as seen during Europe’s deadly 2022 heatwave when western Germany hit 37°C and Munich reached 38°C [1][3]. That event peaked on 4 July before cooler air moved in, indicating that early July can still be volatile. A programmatic trader would model this by pulling Wunderground’s historical daily max for 1 July across the last 20 years, then overlaying current forecast data from AccuWeather, which predicts highs between 68°F and 88°F for July 2026, with an average of 79°F [6].

Key catalysts include the timing of the thundery showers forecast for today and whether cooler northern air arrives before settlement. Traders should monitor the National Weather Service’s hourly updates for Munich Airport, as a moderate warning for high temperature is issued from Thursday 11:00 to Friday 19:00 CEST, suggesting a potential late heat spike [4][5]. If the showers persist and pressure remains high, the temperature will likely stay below the range threshold, reinforcing the 0% probability. A conditional order strategy would trigger a short position if humidity stays above 90% and wind remains east-northeast, both indicators of suppressed heat [2].

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.
