Market context
Chengdu’s highest temperature at Shuangliu airport on 2 August will hinge on whether the city gets the kind of muggy, pre-thunderstorm lift that still allows a sharp afternoon spike. Long-run August climatology points to hot, humid conditions rather than outright extreme heat: typical daytime highs are around 29–31°C, with many guides describing August as Chengdu’s hottest month and noting that sunny breaks can still push readings well above 35°C[3][4][6][7].
That background makes the crowd-implied 0% YES look aggressive only if it is assuming an unusually cool or wet day. Comparable August cases in Chengdu show a broad spread between average highs and rare hot-day extremes, with some sources putting extreme summer highs near 38–39°C and WeatherSpark showing daily highs can exceed 94°F, or about 34.4°C, on rarer occasions[6][7][18]. For this market, the key comparison is not the monthly average but whether the day behaves like a standard cloudy-rainy August afternoon or a clearer, sun-heated one that briefly breaks out of the 30s[2][3][10].
Traders should watch the short-range forecast, satellite/radar trends, and whether thunderstorms arrive early enough to cap the daytime maximum. Chengdu’s August rainfall is frequent and often convective, with several sources flagging around 12–22 rainy days and heavy humidity, which can suppress maximum temperature if showers build before mid-afternoon[2][4][5][11][13]. Because the settlement source is Wunderground’s station record for Chengdu Shuangliu International Airport, the decisive inputs are the local airport forecast, timing of any rain bands, and whether cloud cover holds through the warmest part of the day[market description][3][6].

FAQ
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
