Highest temperature in Beijing on August 8?

Platform comparison

Market context

Beijing’s highest temperature on 8 August 2026 is the key readout, and the market is pricing **0% YES**, so the underdog is any outcome that lands in the upper temperature bands rather than a clearly cooler day. Beijing’s August climate is normally hot, with average daytime highs around **31–32°C** and published August record highs in the high 30s, which makes mid-30s outcomes the natural consensus zone rather than a cold-day surprise.[2][3][10]

For handicapper context, comparable August climate data and recent daily-weather pages point to a city that usually clears 30°C even when it is unsettled, so the favourite is still a warm-to-hot print rather than a drastic cool-off.[4][10][17] The value question is where the market has overdiscounted heat: if cloud cover or rain keeps the airport station below the usual August peak, the lower bands gain contrarian appeal; if the day runs to the seasonal norm, the higher bands remain the more plausible landing zone. Weather Underground’s station-based daily observations are the settlement reference, so the best comparable is the Beijing Capital International Airport reading rather than the broader city forecast.[13]

Traders should watch the same-day aviation-weather setup around Beijing Capital International Airport, especially cloud cover, rainfall, and any afternoon convective development, because those are the factors most likely to cap the daily maximum. The settlement window closes at **12:00 UTC**, which is mid-afternoon local time, so late-morning heating and early-afternoon weather changes matter more than overnight conditions; the historical pages also show Beijing’s August mornings can start warm before the day’s peak is reached.[1][17]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win 2026, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
