Highest temperature in Chongqing on August 10?

Platform comparison

Market context

The event is whether Chongqing’s airport station posts a maximum temperature that lands in the market’s Celsius band, using the Weather Underground **Daily Observations** table rather than any headline high/low summary. August is normally the city’s hottest month, with climatology and travel-weather guides putting typical highs around the mid-30s Celsius and heatwave peaks into the low-40s, so a value in the 34–35°C area is consistent with seasonal norms rather than an outlier.[3][4][6][9][17]

The current 0% implied YES price is hard to reconcile with the forecast set, because market-level guidance has already pointed to a daytime maximum near 34–35°C, while current public forecasts describe very hot, humid conditions and even mention thunderstorms without implying a meaningful cool-down.[2][12][14] That makes the distribution look concentrated around the mid-30s bands, which is the key historical framing for reading a weather market: in Chongqing, modest shifts in cloud cover, rainfall timing, or boundary-layer heating can move the settled outcome by one bracket, but they rarely move it far enough to justify a zero-price view when forecasts are already clustered near the target range.[2][7][13]

For accessibility, the main market-structure issue is not the temperature itself but the venue and user check regime. If the market is offered on a platform affected by Germany’s GlüStV rules, access can be constrained by local gambling-law treatment; in the US, CFTC reach can matter where a product is deemed a regulated derivative or event contract, even if the underlying is weather rather than sport. A “no-KYC up to $1,500” limit generally means a user can transact only below that cumulative threshold without full identity verification, which can make small positions easier but does not remove jurisdictional screening, sanctions checks, or platform-level eligibility limits for this specific market.
