Highest temperature in Chengdu on August 18?

Platform comparison

Market context

Chengdu's August weather will determine whether the highest temperature recorded at Shuangliu International Airport on 18 August 2026 falls into the specified range. The city sits in Sichuan Province at 500 metres elevation, experiencing a humid subtropical climate with monsoon influence during summer months.

Historical August data from Chengdu shows consistent high temperatures in the 29–35°C band, with extremes occasionally reaching 37–38°C during heat waves. The 0% crowd probability suggests traders are pricing in either an unusually cool day or scepticism about the specific range boundaries. August typically represents peak summer heating in the region, with afternoon highs regularly exceeding 32°C. Comparable years show that sustained high-pressure systems over central China drive temperatures above 35°C roughly 40–50% of the time during mid-August, whilst cooler systems or increased cloud cover from monsoon activity can suppress highs to 28–30°C.

Weather Underground's Daily Observations table at Shuangliu station will be the definitive source, with settlement contingent on readings from that specific monitoring point rather than broader city estimates. Traders should monitor extended forecasts from mid-August 2026 for high-pressure positioning over the Yangtze River region and any monsoon system development. The settlement window closes at 12:00 UTC on 18 August, meaning the market resolves based on the calendar day's recorded maximum regardless of when that peak occurs during local daylight hours.

UK Frequently Asked Questions

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.

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 trade Premier League prediction markets from the UK?

Yes. Polymarket has Premier League outcome markets (title winner, relegation, top scorer). For UK traders wanting GBP settlement and UKGC protection, Betfair Exchange and Smarkets offer Premier League futures and match markets. Betfair is the deepest liquidity venue for UK football exchange markets.
