Highest temperature in Beijing on August 21?

Platform comparison

Market context

Beijing's highest temperature on 21 August 2026 will be measured at Capital International Airport Station and resolved against Weather Underground's Daily Observations table rather than the summary high-low figures. The settlement window closes at midday UTC on that date, meaning traders must rely on final recorded readings from the station's instruments during the preceding 24 hours.

Historical August temperatures at Beijing's airport station show consistent patterns worth examining. Over the past decade, peak August highs have ranged between 32°C and 37°C, with late-summer heat waves occasionally pushing toward 38°C. The 0% crowd probability suggests traders are either extremely confident in a specific temperature band or uncertain about which range the market offers. Comparable weather markets on this platform have shown that when probabilities cluster at extremes, resolution often hinges on whether the actual reading falls into a narrower or wider band than anticipated—similar to how Eurovision voting splits between jury and public can dramatically shift outcomes when one constituency dominates unexpectedly.

Traders should monitor China's meteorological forecasts from late July through mid-August 2026, particularly any alerts from the China Meteorological Administration regarding heat waves or unusual pressure systems affecting northern regions. Weather Underground's data feed reliability and any potential station maintenance or recalibration during summer months could affect the Daily Observations table's readings. The specificity of using airport station data rather than city-centre measurements matters considerably, as airport locations often record different microclimatic conditions than urban cores.

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.
