Highest temperature in Chongqing on August 14?

Platform comparison

Market context

On 14 August 2026, the highest temperature recorded at Chongqing Jiangbei International Airport Station will determine this market's settlement. The resolution mechanism relies on the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when intraday peaks diverge from headline highs. Chongqing's summer climate typically produces sustained heat; August averages peak temperatures between 32–35°C, though extremes occasionally exceed 40°C during heat waves.

Historical August temperature records for Chongqing show considerable year-to-year variation. The city recorded 44.5°C in August 2022 during an exceptional heat event, whilst more typical years see maxima in the 33–37°C band. The current crowd-implied probability of 0% suggests traders are pricing in either extreme confidence in a specific temperature range or insufficient liquidity to reflect genuine uncertainty. Comparable Chinese cities—Wuhan, Nanjing—have experienced similar volatility, making single-day forecasts inherently uncertain two years ahead.

Traders monitoring this market should track seasonal climate patterns from June 2026 onwards, including El Niño or La Niña conditions that influence East Asian summer temperatures. The China Meteorological Administration publishes monthly forecasts and heat-wave alerts; these announcements typically drive adjustments in long-range temperature expectations. Regulatory accessibility varies: under German GlüStV rules, weather derivatives require appropriate classification; US CFTC reach extends to US persons regardless of domicile; and platforms offering no-KYC access up to $1,500 notional may restrict this market to verified users depending on jurisdiction and contract size, affecting liquidity depth closer to settlement.
