Highest temperature in Beijing on July 28?

Platform comparison

Market context

Beijing's summer weather in late July typically brings peak heat before the monsoon season gains strength. The city experiences average highs around 29–31°C during this period, though temperatures can exceed 35°C during heat waves. 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 from midnight through noon that day.

Historical records from the China Meteorological Administration show that July temperatures in Beijing have ranged from lows of 24°C to extremes exceeding 40°C over the past two decades. The 2010 heat wave pushed readings above 40°C for multiple consecutive days, whilst cooler Julys have seen highs stabilise in the low 30s. The current 0% implied probability suggests traders expect a reading outside the uppermost temperature bracket offered by the market, though this assessment depends entirely on which specific ranges the market presents.

Traders should monitor seasonal forecasting updates from the China Meteorological Administration in the weeks leading to 28 July, as these typically provide guidance on whether the region will experience anomalous heat or near-normal conditions. The East Asian summer monsoon's timing and intensity directly influences Beijing's late-July temperatures; an early monsoon arrival typically suppresses extreme heat, whilst delayed onset allows heat-wave conditions to persist. Real-time weather data from Wunderground will become the definitive source once the settlement date arrives, with the highest recorded temperature determining the resolution category.

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.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

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.
