Highest temperature in Guangzhou on August 4?

Platform comparison

Market context

Guangzhou’s day hinges on the reading at Baiyun Airport, where the market settles on the **highest temperature recorded on 4 August** rather than an end-of-day average. That matters because a brief afternoon spike, even if followed by rain, can decide the outcome; by 9 a.m. UTC, the crowd’s 0% YES implies traders currently see the airport station as very unlikely to reach the relevant band.

The useful historical frame is that August in Guangzhou is normally **hot, humid, and rain-prone**, with typical highs in the low 30s Celsius and frequent showers or thunderstorms, so a single-day maximum can still overshoot the mean even in unsettled weather.[1][10][14] Comparable weather guides put August highs around 33°C and note that rain is often heavy but short-lived, which is the classic pattern for a late-day temperature pop rather than a flat, suppressed profile.[2][15] The current crowd price therefore looks less like a pure weather call and more like a judgement on how much cooling rain and cloud cover will cap the airport’s peak.

For catalysts, traders should watch the official forecast and any same-day updates around the Baiyun Airport observation, especially if convective rain clears early enough for strong heating before the afternoon maximum.[6][8] Recent forecasts for Guangzhou show high temperatures around 31–33°C with rain in the mix, while some daily outlooks place 4 August at roughly 33°C/26°C with moderate or heavy showers, which leaves room for a respectable peak if sunshine breaks through.[2][8][12] Because the market resolves from Wunderground’s airport station history, the key dependency is the station’s recorded maximum, not citywide weather headlines or neighbourhood conditions.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.
