Highest temperature in Beijing on August 21?

Platform comparison

Market context

Beijing's weather on 21 August 2026 will be shaped by the tail end of summer monsoon patterns typical for northern China at that time of year. August temperatures in Beijing historically peak in the mid-to-high 30s Celsius, with daily highs frequently reaching 35–37°C during the height of summer. The specific reading will depend on atmospheric pressure systems moving across the region and any residual moisture from tropical cyclone activity in the western Pacific, which can either suppress or amplify heat accumulation.

Historical August data from Beijing Capital International Airport shows considerable year-to-year variation. The station has recorded August highs ranging from around 32°C during cooler years influenced by monsoon troughs to 38–39°C during particularly hot spells. The 0% crowd probability suggests traders expect the market's temperature thresholds to sit above what typical late-August conditions would produce, or that the resolution criteria—specifically the Daily Observations table rather than summary figures—creates ambiguity about which measurement will ultimately govern the outcome.

Traders should monitor long-range forecasts from late July 2026 onwards, particularly any alerts from China's meteorological authority regarding heat waves or unusual atmospheric patterns. The settlement window closes at midday UTC on 21 August, meaning the highest temperature recorded up to that point at the airport station will determine resolution. Any discrepancy between Weather Underground's Daily Observations and Day High & Low sections could prove decisive, making source verification critical before the market settles.

UK Frequently Asked Questions

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.
