Highest temperature in Munich on July 9?

Platform comparison

Market context

The underlying event is the peak temperature recorded at Munich Airport on 9 July 2026, measured in degrees Celsius and resolved via Wunderground data. Historical patterns for Munich in July show daily highs typically ranging between 21°C and 32°C, rarely dipping below 16°C or exceeding 37°C[1][3]. The current crowd-implied probability of 0% for a 28°C threshold suggests the market expects temperatures to stay below this bracket, yet this contradicts the average high of 25°C and the frequent occurrence of days reaching 28°C or higher in recent summers[1][2]. Programmatic traders would likely back-test Wunderground archives for the station EDDM to identify how often July 9 specifically hits the 28°C range, treating the 0% signal as a potential mispricing if historical frequency exceeds current odds.

Key catalysts include the immediate weather forecast for Munich, which currently shows sunny intervals with a gentle breeze and a temperature of 53°F (12°C) on 9 July, well below the 28°C threshold[6][8]. However, forecast models for July 2026 indicate daily highs could reach up to 32°C, with the average high at 25°C, meaning a sudden heat spike remains plausible[2]. Traders should monitor real-time updates from the National Weather Service for Munich Airport and Wunderground’s live hourly data, as a rapid shift in wind patterns or cloud cover could alter the peak temperature before the settlement window closes[7]. A recent report noting Germany’s record high of 41.3°C in June 2026 underscores the potential for extreme heat events, even if current conditions appear mild[5]. Conditional order bots would likely set alerts for temperature breaches above 27°C to capture late-market moves before the 12:00 UTC deadline.

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 Polymarket Bot UK, which mirrors the Polymarket order book directly.

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.
