Pronóstico: Highest temperature in Beijing on August 4?

Platform comparison

Market context

Beijing is set for a hot, humid day with several forecasts clustering the afternoon high around the low-to-mid 30s Celsius, but also flagging showers and thunderstorms that can cap the peak temperature. Rambler’s hourly forecast has temperatures rising from 25–29°C through the day, with 29°C shown at 15:00 and precipitation listed in several time slots, while Travel China Guide puts 4 August at 31.5°C for Beijing and AccuWeather’s monthly view has early-August highs mostly in the high 80s to around 90°F, which is roughly 31–32°C.[1][4][2]

That makes the market’s 0% YES reading look out of line with the weather setup. Beijing’s August climatology is firmly summer-like, with typical highs around 30–32°C and frequent rain, so the key question is not whether it will be warm, but whether cloud cover or rain knocks the airport station below the higher buckets. Comparable forecasts for 4 August 2026 are centred on 31–36°C across different providers, which would place the likely outcome in the mid-range rather than the extreme ends.[3][6][12]

Traders should watch for late-day convection, since the market resolves on the highest temperature recorded at Beijing Capital International Airport Station during the full day, not just the afternoon forecast high. Any update that shifts rainfall timing, thunderstorm coverage, or wind could move the top reading by a degree or two, and the resolution source is Wunderground’s daily history page for ZBAA. The market text also notes revisions remain relevant until the first datapoint for the following date is published, so any late corrections to the station record can still matter within the settlement window.[13]

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.
