Pronóstico: Highest temperature in Guangzhou on August 4?

Platform comparison

Market context

Guangzhou’s highest temperature on 4 August will be set by the Guangzhou Baiyun International Airport Station reading, and the market is effectively asking whether the day’s top observation lands in a hotter bracket than traders now expect. Early August is normally one of the city’s hottest periods, with typical August highs around 33°C to 34°C and sticky humidity that keeps apparent heat elevated even when showers break out.[1][3][10]

That backdrop matters because the current 0% YES price implies the market is not pricing in an unusually hot spike. Comparable August forecasts for Guangzhou still cluster in the low-to-mid 30s Celsius, while some sources show heavy shower risk on 4 August itself, which can cap the daytime maximum if storms arrive early or persist.[2][6][11] By contrast, travel and climate guides consistently describe August as hot, humid and rain-prone, with occasional days reaching the mid-30s, so a modest upside surprise remains plausible if cloud cover clears after morning rain.[13][18]

Traders should watch the airport station observation cycle and any same-day convective rainfall or thunderstorm warnings, because the settlement uses the *highest* temperature recorded during the whole day rather than the forecast peak alone. Current forecasts also point to showers and high humidity around Guangzhou, and BBC Weather’s Baiyun Airport observations underline that conditions can shift quickly from muggy to rainy in a single day.[7][17] If the heaviest rain arrives before the warmest part of the afternoon, the market can stay pinned low; if sunshine breaks through after showers, the ceiling on the day’s maximum rises materially.[11][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.

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 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.
