Pronóstico: Highest temperature in Guangzhou on August 1?

Platform comparison

Market context

Guangzhou Baiyun International Airport is already in its wet, humid summer pattern, and the key market question is not whether the city stays hot but whether the day’s peak clears the next Fahrenheit-to-Celsius band on the Wunderground table. Late-July and early-August climate normals put Guangzhou around 32–33°C for daytime highs, with August averages clustered near 33°C and lows around 25–27°C, so the distribution sits squarely in the mid-30s Celsius rather than at extremes[1][4][20]. That makes the exact settlement bucket sensitive to any modest cooling from cloud cover or rain, even if the broader seasonal baseline remains firmly hot.

The market’s 0% YES price is hard to reconcile with the local climatology, because published August histories and monthly summaries repeatedly show typical highs in the 33–36°C range, and some August days have reached 37°C or even 39°C in Guangzhou’s broader climate record[4][20]. Comparable August data for the city also show many days above 33°C, which means the practical question is whether airport conditions match the citywide heat profile or are trimmed by precipitation and sea-breeze effects[1][4][18]. For a high-only market, the upper tail matters more than the daily average, and Guangzhou’s summer record keeps that tail open.

What traders should watch is the live forecast around the airport station: the first- and second-half-of-day temperature path, any rain bands, and whether cloud cover suppresses the afternoon maximum before the settlement window closes at 12:00 UTC. Guangzhou’s August weather is frequently humid and rainy, with average rainfall and rain-day counts high enough to blunt peak temperatures on some dates[2][14][16]. AccuWeather’s August outlook for Guangzhou currently shows daily highs broadly in the low 90s °F, or about 32–34°C, which is consistent with the historical range and would normally leave several settlement bands live rather than collapsing the market to the lowest outcomes[12].

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.
