Highest temperature in Guangzhou on July 31?

Platform comparison

Market context

Guangzhou’s 31 July reading is set by the highest temperature at Baiyun International Airport, so the key question is whether the day finishes with a modest mid-30s Celsius high or a sharper spike. July is normally the city’s hottest month, with average highs around 30–33°C and frequent humidity and rain, but official-style forecast pages for late July 2026 still point to a hot afternoon, with highs near 34–37°C and a meaningful thunderstorm risk. [1][2][16][19]

The current 0% YES price looks more like a voting landslide than a weather market, and it should be read through precedent: in summer-airport temperature markets, the public often discounts the chance of a late-day peak when rain is forecast early, even though the settlement depends on the maximum observed at any point before the window closes. That makes this closer to an Oscars-style split between a visible front-runner and the hidden final tally than a simple day-time forecast, because a brief hot burst can matter more than the all-day average. [2][12][13]

Traders should watch the timing of convective thunderstorms, cloud breaks and the exact airport observation feeds rather than the city-wide forecast alone. BBC Weather currently shows Baiyun Airport at 30°C with very high humidity, while other late-July outlooks call for thundery showers and temperatures capable of reaching the mid-30s, so the main catalyst is whether heat builds before rain suppresses the peak. If showers arrive late, the highest reading can still land well above the morning level; if they arrive early, the range may resolve lower than headline forecasts suggest. [3][6][8][11]

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.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.
