Highest temperature in Munich on July 1?

Platform comparison

Market context

The real-world event is the highest temperature recorded at Munich Airport on 1 July 2026, measured in degrees Celsius and resolved via Wunderground data. The market currently shows a 0% probability for the "YES" outcome, yet the frontrunner is 21°C at 77%, with 22°C trailing at 21%[1]. This stark divergence between the binary "YES" probability and the specific temperature distribution suggests the binary contract is mispriced or the "YES" condition is defined against an implausible threshold. Historical July highs at Munich International Airport typically range from 72°F to 75°F (22°C to 24°C), rarely exceeding 87°F (31°C)[4]. A recent extreme heatwave in western Germany saw Munich hit 38°C on 4 July, before cooler northern air dropped temperatures to 28°C by 5 July[3]. These comparable cases frame the 21–22°C frontrunners as conservative but plausible, making the 0% binary probability appear inconsistent with the underlying temperature distribution.

A programmatically minded trader should monitor the Wunderground API endpoint for real-time updates and cross-reference with the Met Office seven-day forecast for Munich International, which includes warnings on high temperature and UV levels[10]. The key catalyst is the arrival of thundery showers forecast for Wednesday 1st July, with a high of 23°C (73°F) and lows of 12°C (54°F)[7]. These showers act as a natural cooling dependency, potentially capping the day’s peak below the 21°C frontrunner if they persist through the afternoon. Traders using conditional orders should watch for the timing of precipitation onset, as a delay could allow temperatures to climb higher before the cooling effect. The settlement window ends 12:00 UTC on 1 July 2026, so any data lag from Wunderground must be accounted for in automated strategies[1]. No recent news announcements override these weather dependencies, but the BBC Weather report confirms the thundery pattern is active as of 6 AM UTC[7].

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
