Highest temperature in Beijing on July 21?

Platform comparison

Market context

Beijing's highest temperature on 21 July 2026 will be measured at Capital International Airport Station and reported in Celsius via Wunderground's historical database. July is Beijing's peak summer month, with average highs around 29–30°C, though heat waves regularly push readings into the mid-to-high 30s. The 0% crowd probability suggests either extreme confidence in a specific temperature band or insufficient liquidity to establish a baseline view.

Historical July data from Beijing shows considerable year-to-year variance. In July 2022, the city recorded 40.3°C; in July 2023, the peak was 35.1°C. This volatility reflects the influence of monsoon patterns and occasional high-pressure systems that can drive temperatures well above the monthly mean. Comparable weather prediction markets typically see probability mass distributed across multiple temperature ranges rather than concentrated at zero, indicating this market's current state may reflect thin trading rather than genuine consensus.

From a regulatory standpoint, this market operates under distinct frameworks depending on trader location. German traders fall under GlüStV (Glücksspielstaatsvertrag) oversight, which treats prediction markets as gaming products subject to licensing requirements. US CFTC jurisdiction applies to certain derivatives, though weather derivatives have historically occupied grey areas. Iskalshilegit's no-KYC threshold up to $1,500 USD means traders in compliant jurisdictions can access this market without identity verification below that stake level, though position limits and settlement procedures remain subject to platform terms and applicable local law.
