Highest temperature in Guangzhou on July 25?

Platform comparison

Market context

On 25 July 2026, the highest temperature recorded at Guangzhou Baiyun International Airport Station will determine the settlement outcome. Guangzhou's summer climate is characterised by high heat and humidity; July is typically the hottest month, with historical daily maxima frequently exceeding 33°C. The resolution will depend on official meteorological data from Wunderground's historical records for that specific date and location.

The 0% crowd probability reflects uncertainty inherent in weather prediction markets rather than an expectation that no temperature will be recorded. Comparable July temperature ranges in Guangzhou show consistent clustering between 32–36°C over the past decade, with occasional excursions beyond 37°C during heat waves. Historical volatility in summer extremes—driven by monsoon patterns and urban heat island effects—suggests that multiple temperature bands remain plausible outcomes, yet the crowd's current positioning indicates scepticism about higher thresholds or specific narrow ranges.

Traders should monitor China Meteorological Administration forecasts and tropical cyclone activity in the South China Sea, both of which can materially shift July temperatures in Guangzhou. Regulatory accessibility for this market varies by jurisdiction: under German GlüStV rules, prediction markets require licensing; US CFTC oversight applies to derivatives contracts on US persons; and many platforms offer no-KYC participation up to $1,500 notional exposure, permitting retail engagement without identity verification below that threshold. Settlement closes at 12:00 UTC on 25 July 2026, aligning with the airport station's daily observation window.
