Highest temperature in Chengdu on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Chengdu Shuangliu International Airport Station will be measured and reported via Weather Underground's Daily Observations table. Chengdu, located in Sichuan Province, experiences a subtropical humid climate with August typically among its warmest months; historical August highs at the airport station range between 32–35 °C, though extreme heat events occasionally push readings above 37 °C. The resolution will depend on the specific instrumental reading logged in Weather Underground's primary data source, not summary figures, creating a precise settlement criterion tied to a single meteorological station's records.

The 0% crowd probability reflects either extreme confidence in a specific temperature range or minimal trading activity. Comparable August temperature markets for major Chinese cities show that late-summer highs cluster predictably within narrow bands unless disrupted by unusual atmospheric patterns—heatwaves or tropical systems—that shift regional conditions sharply. Recent years have seen Chengdu experience occasional August peaks above historical norms; the 2022 and 2023 summer seasons recorded multiple days exceeding 38 °C across central China, establishing precedent for elevated outcomes.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV rules, prediction markets require licensing; traders in Germany face restrictions unless the operator holds appropriate authorisation. US CFTC oversight applies to binary derivatives; US persons may face limitations on participation. The "no-KYC up to $1,500" threshold, where offered, typically permits small-stake participation without identity verification, lowering barriers for casual traders whilst maintaining compliance thresholds for larger positions. Traders should verify their own regulatory status before committing capital.
