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 settlement based on Wunderground’s daily maximum in degrees Celsius. Historical July data shows the city routinely hits 31°C, with occasional spikes to 35°C during humid, warm spells, while the month averages 185 mm of rainfall and roughly 13 rainy days, often featuring afternoon thunderstorms that can temporarily suppress peak temperatures [1].

The current 0% crowd-implied probability for any specific range suggests the market expects an extreme outlier or is mispricing the baseline; comparable July 20 days in recent years have consistently fallen within the 28–34°C band, making a result below 25°C or above 36°C statistically improbable given the typical humid summer climate and frequent convective rain that limits sustained heat extremes [1].

Traders should monitor real-time updates from Wunderground’s daily history page for the ZBAA station as the settlement window closes at 12:00 UTC on 20 July 2026, watching for any sudden shifts in cloud cover or thunderstorm timing that could alter the daily maximum [1]. No external announcements or injury news apply here, as the outcome depends solely on observed meteorological conditions at the airport station, with the primary dependency being the precise timing of afternoon convective activity typical of Beijing’s wet July season [1].

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.

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.

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.

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.
