Highest temperature in Beijing on July 20?

Platform comparison

Market context

Beijing’s highest temperature on 20 July 2026 will be recorded at the Beijing Capital International Airport Station, with the market resolving to the Celsius range containing that peak. The settlement relies on Wunderground’s daily history for ZBAA, capturing the single highest reading across all times on that date.

Historically, mid-July in Beijing sees warm, humid conditions with typical highs between 23°C and 31°C, making the current 0% YES probability for any specific range appear misaligned with seasonal norms unless the market is betting on an unusually cool day [1]. July is also one of the wettest months, averaging 185 mm of rainfall, which can suppress peak temperatures through cloud cover and precipitation [1]. Comparable years show that while 31°C is common, extremes above 35°C are rare but not impossible during dry spells, suggesting the zero probability may reflect a narrow definition of the YES range rather than a genuine expectation of cool weather.

Traders should monitor Wunderground’s live daily update for ZBAA as the settlement window closes at 12:00 UTC on 20 July 2026, watching for any sudden shifts in the recorded peak. No external announcements or injury news apply here, but real-time weather bulletins from China’s Meteorological Administration could signal unexpected cloud cover or rain that would lower the maximum temperature. The key dependency is the final Wunderground entry, which will be the sole resolution source, so any discrepancy between forecast models and the actual recorded value will determine the outcome.

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.

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.
