Highest temperature in Guangzhou on July 31?

Platform comparison

Market context

Guangzhou on 31 July is usually a **hot, humid, and storm-prone** setup rather than a day for standout extremes, with July highs typically around 30–33°C and frequent rain or thunderstorms. Current guidance still points to a warm afternoon, with forecast highs clustered around 31–34°C and some models carrying a thunderstorm risk, which is consistent with the city’s normal late-July pattern.[1][2][7][17]

That backdrop makes a **0% YES** on an unusually high outcome understandable if the market is looking for an extreme top-end reading rather than a routine summer maximum. Comparable July climatology shows Guangzhou’s daily highs are often near 91°F/33°C, with rare excursions into the mid-30s Celsius, while the airport station observation base sits in a very humid coastal environment that can cap peak heat when cloud and showers build early.[3][12][13][18]

For traders, the main catalysts are the **day-of forecast updates** and whether convection arrives early enough to blunt the afternoon peak. AccuWeather and BBC both show Guangzhou with morning humidity already high and showers or thunderstorms in the mix, so the decisive signal is whether the midday sky stays bright long enough for surface temperatures to push into the upper forecast band.[1][3][8][11] Wunderground’s airport-station history page is the settlement source, so the live read to watch is the highest recorded temperature at Guangzhou Baiyun International Airport rather than citywide averages.[8]

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.

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.

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.
