Highest temperature in Chengdu on July 24?

Platform comparison

Market context

Chengdu’s airport high for 24 July is a straightforward **summer heat** call, and the market is currently priced like an extreme downside shot with a **0% YES implied probability**. In handicapper terms, that makes the favourite the lower temperature bands, while any trade above the market’s consensus is a clear contrarian angle; the practical question is whether the day can get hot enough to land in a higher Celsius bucket at Chengdu Shuangliu International Airport Station.

Historically, Chengdu’s July climate is warm and humid, but it is also in the middle of the rainy season, which can cap extremes if cloud cover or showers build through the afternoon. Forecast snapshots for the city today point to already hot conditions, with current readings around **38°C** and modelled highs in the mid-30s Celsius, while other forecasts still show rain chances later in the day.[3][4] That split supports a classic market read: the consensus sits with a hot-but-not-record-breaking day, but the value may lie in the higher temperature ranges if the heat holds before convective rain arrives.[1][5]

For catalysts, traders should watch the hourly evolution of cloud cover, thunderstorm timing, and any late-day rain that could suppress the maximum before the Wunderground daily high is fixed at the airport station. The key dependency is simple: if the hottest part of the day lands before showers, the upper bands gain; if rain or thick cloud arrives early, the market leans back towards the cooler side. Current live forecast services already disagree on how much rain will interrupt the heat, which is exactly where a small mispricing can persist in a market showing zero implied probability for the YES side.[2][3][4]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
