Highest temperature in Shenzhen on August 16?

Platform comparison

Market context

On 16 August 2026, the highest temperature recorded at Shenzhen Bao'an International Airport will determine this market's resolution. The settlement uses the Daily Observations table from Weather Underground as the authoritative source, not the summary Day High & Low figures, which occasionally diverge. Shenzhen's August climate typically peaks between 32–35°C, though extreme heat events can push readings higher. The specific temperature bracket that captures the daily maximum will trigger resolution.

Historical August temperatures at Bao'an show consistent volatility. Since 2015, the station has recorded August highs ranging from 31°C to 37°C, with the 2013 peak of 38.9°C remaining the regional benchmark for extreme heat. The current 0% crowd probability suggests traders are pricing in either confidence in a specific temperature range or insufficient liquidity to establish baseline odds. Comparable single-day weather markets typically see probability clustering around historical medians once trading volume increases; the absence of early positioning here reflects either early-stage market formation or consensus around a narrow outcome band.

Traders should monitor China Meteorological Administration forecasts released in early August 2026, particularly any heat wave alerts or tropical cyclone activity affecting southern Guangdong. El Niño or La Niña conditions in the preceding months influence August temperatures materially. From a regulatory standpoint, this market operates under German GlüStV provisions where applicable, with US CFTC reach extending to US-based traders. The no-KYC threshold of $1,500 applies to aggregate position value; traders in jurisdictions requiring identity verification should verify their local rules before participation, though this market's weather-derivative classification typically falls outside traditional derivatives regulation in most territories.
