Highest temperature in Guangzhou on July 23?

Platform comparison

Market context

Guangzhou’s airport is the settlement source, so the key question is not citywide comfort but the day’s *single highest reading* at Guangzhou Baiyun International Airport Station. With the crowd assigning 0% to “YES” for the market’s implied setup, the pricing looks detached from the climatological norm: July in Guangzhou is typically hot and wet, with average highs around 32°C and frequent rain, which can mute peaks but does not prevent short-lived surges in temperature.[4][1]

For context, the current market is already leaning towards the mid-30s Celsius rather than an extreme spike, with 36°C the frontrunner and 35°C close behind.[1] On a day with Guangzhou’s usual summer humidity, the highest official airport reading can still come from a brief clearing or a late-morning warm-up before cloud cover and convection build, so traders should treat the early temperature trend as more informative than the city’s headline “feels like” figure.[2][4]

The main catalysts are the live hourly observations from the airport station and any change in cloud, rain, or thunderstorm coverage through the day; those are the dependencies most likely to cap or extend the maximum. AccuWeather currently shows Guangzhou under cloud with very high apparent heat and humid conditions, which is consistent with a warm start even if later cloud or rainfall limits the final peak.[2] Wunderground’s daily history page will be decisive for settlement, so the market should be read through the lens of whether the airport reaches 35°C, 36°C, or higher before conditions deteriorate.[1][2]

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.
