Highest temperature in Chengdu on July 24?

Platform comparison

Market context

Chengdu’s hottest reading on 24 July will be driven by conditions at Shuangliu Airport, where July normals usually sit in the mid-20s Celsius but daytime peaks can still reach the low-to-mid 30s, with some summer days pushing towards 38°C. Forecast pages for Chengdu today show high temperatures around 35°C, which is consistent with the city’s hot, humid summer pattern and leaves the market’s key question as whether the airport station prints a very warm top end rather than simply a pleasant midsummer high.[4][7]

The 0% crowd-implied yes price can be read against how these temperature markets usually behave: they are often range-sensitive, because the settlement depends on the single highest reading on the day, not the average or the afternoon forecast. On Polymarket, the quote is typically shown as an implied probability, so 0% indicates no visible support for the relevant range; Kalshi and Betfair more often display prices as decimal odds or exchange-style prices, while Smarkets quotes decimals with commission, so the same underlying view can look cheaper or more expensive after fees and spread are included. KYC access also matters: Polymarket access is more restricted than many regulated books, whereas Kalshi and Smarkets generally require identity checks in eligible jurisdictions, and Betfair’s availability depends on local regulation and exchange access.

For traders, the main catalysts are the day’s actual weather evolution, especially sunshine, cloud cover, rain showers and any late-afternoon heating that could lift the airport’s maximum beyond the morning consensus. Chengdu forecast feeds today point to sunny or partly sunny conditions with a meaningful rain chance later in the day, and that combination matters because short-lived cloud breaks can change the eventual high by a couple of degrees. With settlement based on Wunderground’s daily high for Chengdu Shuangliu International Airport Station, the most relevant watchpoints are hourly updates, radar trends and any shift in convective rain timing before the station’s final daily maximum is locked in.[2][7]
