Highest temperature in Munich on June 29?

Platform comparison

Market context

The underlying real-world event is the highest temperature recorded at Munich Airport on 29 June 2026, measured in degrees Celsius. On Polymarket, this contract currently prices the "30°C" outcome at 28% probability, with "29°C" trailing at 26%, while the market assigns a 0% chance to temperatures exceeding 30°C. Traders settle in USDC on the Polygon network using conditional tokens, meaning the on-chain mechanics lock the price based on current crowd sentiment rather than the abstract weather event itself.

Historical context frames this low probability against a record-breaking European heatwave that recently pushed temperatures above 40°C across Western Europe, with Germany recording a new national high of 41.5°C just two days prior[2]. Munich itself hit 36°C during this surge, yet the market remains cautious about exceeding 30°C on this specific date, perhaps due to the typical June average high of 79°F (26°C) in the region[3]. The recent extreme heat suggests volatility, but the current 0% YES probability for higher ranges implies traders expect a cooling trend or cloud cover to limit the peak.

Key catalysts include the official Wunderground data release at 12:00 UTC on 29 June, which will resolve the market, and any sudden shifts in the eastward-moving heatwave forecast[1]. Traders should monitor the Al Jazeera report confirming the heatwave's link to man-made climate change, which has made night-time temperatures 100 times more likely than two decades ago[2]. The settlement window closes strictly at 12:00 UTC, so any delay in the first data point publication will prevent resolution until the source updates[1].
