Highest temperature in Guangzhou on August 17?

Platform comparison

Market context

Guangzhou will experience peak summer heat on 17 August 2026, with the highest temperature recorded at Baiyun International Airport determining the settlement outcome. August represents the tail end of Guangzhou's monsoon season, though rainfall typically diminishes by mid-month, leaving predominantly hot and humid conditions. Historical August data from the airport station shows daily highs consistently ranging between 32–35°C, with occasional peaks exceeding 36°C during particularly intense heat waves.

The 0% crowd probability suggests traders are pricing in either extreme confidence in a specific temperature band or uncertainty about which range the market offers. Guangzhou's August climate is remarkably consistent year-on-year; the city sits at 23°N latitude with subtropical characteristics that produce little variance in peak daily temperatures during this period. Comparable August 17th observations from prior years would provide the most reliable baseline, though broader August patterns indicate sustained heat without the dramatic spikes seen in June or July when pre-monsoon conditions peak.

Traders should monitor any tropical cyclone activity in the South China Sea during early-to-mid August, as systems tracking towards the Pearl River Delta region could suppress temperatures through cloud cover and precipitation. The resolution methodology specifies Weather Underground's Daily Observations table at Baiyun station as the binding source, making data quality and station consistency critical factors. Any equipment maintenance or reporting anomalies at the airport weather station in the weeks preceding 17 August could affect measurement reliability.

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.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

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.

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.
