Highest temperature in Beijing on July 28?

Platform comparison

Market context

Beijing experiences peak summer heat in late July, with the city's monsoon season and urban heat island effect combining to drive temperatures well above 30°C. The settlement window closes at midday on 28 July 2026, meaning the market resolves based on the highest temperature recorded at Beijing Capital International Airport Station during that calendar day. Historical data from Wunderground shows that late July temperatures at this station typically range between 32–35°C, with occasional spikes above 36°C during particularly intense heat waves.

The 0% crowd probability suggests traders are pricing in an expectation that the highest temperature will fall below the lowest threshold offered in the market's range options. This appears miscalibrated against Beijing's climatological norms. The city has recorded temperatures exceeding 40°C in previous summers, though such extremes remain uncommon. More typical late-July highs cluster around 33–34°C, making mid-range outcomes substantially more probable than the current odds reflect.

Traders should monitor China's meteorological forecasts released in the week preceding 28 July, particularly any alerts from the China Meteorological Administration regarding heat waves or unusual atmospheric patterns. The North China Plain's weather systems can shift rapidly, and any tropical cyclone activity in the western Pacific could redirect moisture patterns northward, potentially moderating temperatures. Real-time satellite imagery and synoptic charts from late July will provide clearer signals than long-range models, given the inherent uncertainty in seasonal forecasting.

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.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

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.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
