Highest temperature in Guangzhou on August 1?

Platform comparison

Market context

Guangzhou’s Baiyun Airport is entering one of its steamiest stretches: August climate normals point to daily highs around 32–33°C, with humidity and frequent rain making the heat feel more oppressive than the thermometer alone suggests.[1][2][9] For a market on the *single-day high* at the airport station, that matters because the distribution is usually anchored in the low-to-mid 30s, with occasional spikes towards the mid-30s when showers hold off and sunshine builds through late morning and early afternoon.[2][5][18]

The current **0% YES** price looks hard to reconcile with the seasonal base rate unless the market’s YES band is set unusually high. Comparable August guides for Guangzhou repeatedly show typical highs around 33–34°C, and some 2026-facing forecasts still cluster near 35–36°C for 1 August, even while calling for rain.[4][5][13] That means a trader should treat the market as highly sensitive to the exact settlement interval and to which temperature bucket counts as YES, rather than to broad month-level averages alone.[4][16]

The main catalysts are the day’s local weather sequence: early cloud cover, afternoon thunderstorm timing, and whether rain arrives before the usual peak heating window. Guangzhou’s August weather is often driven by sudden showers and tropical disturbance risk, with heavy rain and humidity common enough to suppress highs, but not so dominant that a warm, dry spell is impossible.[2][3][11] If any updated forecast highlights a stronger rain band, higher cloud cover, or tropical cyclone influence, that would argue for a lower final maximum; if the morning stays bright and humid, the airport can still reach the low-to-mid 30s before precipitation curbs the temperature.[2][15][18]

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.

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.

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.
