Highest temperature in Qingdao on July 7?

Platform comparison

Market context

On 7 July 2026, the highest temperature recorded at Qingdao Jiaodong International Airport will determine the outcome of this weather market, with settlement based on Wunderground’s daily peak reading in degrees Celsius. Historical data shows Qingdao’s July highs typically average 29°C, with extremes reaching 33.1°C in August 2018, though no recorded peak has matched the 0% crowd-implied probability for a “YES” outcome suggesting an impossible or mispriced range [3][6]. The current 0% probability likely reflects a market error or a resolution range that excludes all plausible historical and climatological outcomes for early July in this coastal city.

Traders should monitor real-time Wunderground updates for the Jiaodong station as the day progresses, alongside regional forecasts from China’s meteorological authority for any sudden heat anomalies. While no specific announcement is scheduled for this date, the settlement hinges entirely on the single-day peak temperature, making intraday volatility the primary catalyst [7]. Given the settlement window ends at 12:00 UTC, liquidity and book depth will depend on users’ ability to deposit via Klarna or SEPA and withdraw in USDC without on-ramp friction, as funding flows directly correlate with market participation and price discovery efficiency.
