Highest temperature in Chengdu on July 31?

Platform comparison

Market context

Chengdu’s high for 31 July will be set by the afternoon peak at Shuangliu airport, not by the morning reading, so traders should focus on whether the day gets enough heating between rain bands to lift the station above the low-30s Celsius. Current forecasts are clustered around a high of 33°C to 35°C, with some models briefly pushing 37°C, which leaves the market’s 0% YES price looking disconnected from the prevailing weather outlook.[2][10][14]

July in Chengdu is typically hot, humid and very wet, but it still produces high daytime readings when cloud cover breaks. Historical July guides put the city’s usual daytime highs around 31°C to 33°C, while airport-linked forecasts for 31 July show similar or slightly higher values, including 33°C from yr.no and 35.7°C from a local travel weather guide.[2][12][20] That means the main comparison case is not an extreme heat event, but an ordinary midsummer warm spell with enough upside to move the settlement band if sunshine is stronger than expected.[6][12]

The key catalysts are the short-range updates from forecast providers and any shift in convection or rainfall timing over the airport itself. BBC Weather, Meteoblue-style hourly products and other live forecast pages already show warm, humid conditions and some rain risk, so a delayed storm or more afternoon sun would be the main drivers of a higher maximum.[3][4][9][11] Traders should also watch whether the forecast converges towards the more aggressive 35°C-plus readings or back towards the low 30s, because that range determines whether the market resolves inside the upper temperature bands.[10][14]

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

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.

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.
