Highest temperature in Guangzhou on July 9?

Platform comparison

Market context

The real-world event this market tracks is the peak daytime heat recorded at Guangzhou Baiyun International Airport on 9 July 2026, measured in degrees Celsius. Historical data confirms July is Guangzhou’s hottest month, with average highs around 33°C and peaks frequently reaching 36°C or higher[3][4]. Recent forecasts for July 2026 suggest daily highs between 87°F and 100°F (roughly 31°C to 38°C), making a sub-31°C maximum highly improbable and aligning with the crowd-implied 0% probability for lower ranges[2]. Comparable early-July records show highs clustered between 31°C and 34°C, reinforcing that temperatures below this band are exceptional outliers rather than typical conditions[8].

Traders should monitor official weather bulletins from the China Meteorological Administration and real-time updates on Wunderground, the designated resolution source[1]. A key catalyst is the timing of monsoon activity; while July brings heavy rain, brief sunny spells can still drive temperatures toward 36°C, as seen in recent May records where peaks hit 36.3°C[5]. Regulatory accessibility also matters: under German GlüStV rules, prediction markets may require KYC depending on jurisdiction, whereas US CFTC reach implies stricter oversight for larger bets. The “no-KYC up to $1,500” threshold allows casual traders to access this market without identity verification, provided their stake stays within that limit, enhancing liquidity for smaller participants.

Is there a withdrawal cap?
