Highest temperature in Qingdao on June 29?

Platform comparison

Market context

The real-world event centres on the peak temperature recorded at Qingdao Jiaodong International Airport on 29 June 2026, with the market currently pricing a 30°C or higher outcome at just 1% implied probability. This figure stands in stark contrast to trader consensus on comparable dates, where Polymarket lines for 25 June show a 75% probability for the same threshold, and 27 June data suggests a near-certain 100% chance of exceeding 32°C[1][3]. Historical averages for Qingdao in June hover between 24°C and 28°C, yet the warm season typically pushes daily highs above 25°C, with the hottest month often reaching 33°C in late summer[2][7]. The divergence between the 1% price for 29 June and the 75–100% probabilities for earlier dates signals a meaningful mispricing, potentially reflecting an overreaction to typical late-June cooling or a failure to account for the region’s consistent warming trend[1].

Traders should monitor the daily forecast updates from AccuWeather, which project June 2026 highs between 79°F and 84°F (26°C–29°C), alongside Wunderground’s real-time station data for the airport[5]. The settlement window closes at 12:00 UTC on 29 June, meaning any sudden heatwave or cloud-cover shift before midday could alter the outcome[1]. Recent weather records indicate Qingdao’s hottest day reached 33.1°C in August 2018, suggesting that even a brief spike above 30°C remains plausible despite the current 1% price[7]. Analyst consensus heavily favours a daily maximum of 30°C or higher in late June, making the current odds a clear outlier against established seasonal patterns[1]. The key dependency is whether the airport station records a temperature spike before the settlement deadline, as Wunderground’s data will be the sole resolution source[1].
