Highest temperature in Beijing on August 17?

Platform comparison

Market context

On 17 August 2026, the highest temperature recorded at Beijing Capital International Airport Station will fall into one of several defined ranges measured in degrees Celsius. Weather Underground's Daily Observations table—not the summary Day High & Low section—will serve as the authoritative source for settlement, a distinction that matters when automated feeds and manual records diverge. Beijing's August climate typically peaks between 28–35 °C, though heat waves can push readings higher; the 0% crowd probability suggests traders currently see little conviction in whichever temperature band this market's upper threshold represents.

Historical August temperatures at Beijing's airport station show consistent patterns: the past decade's daily highs have ranged from 22 °C during cooler spells to 37–38 °C during intense heat events, with mid-range outcomes (30–34 °C) most frequent. The current probability distribution reflects either extreme confidence that the settlement range is unlikely, or sparse trading activity. Comparable weather markets on this platform typically see probability shifts only when seasonal forecasts update or when real-time meteorological alerts emerge within 7–10 days of the event date.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV rules, prediction markets on weather outcomes face classification scrutiny; US CFTC oversight applies if the platform accepts US traders, though weather derivatives historically receive lighter treatment than financial index contracts. The no-KYC threshold up to $1,500 USD means traders in certain regions can participate without identity verification below that stake level, though platform terms and local law determine actual eligibility. Settlement timing (12:00 UTC on 17 August) aligns with Beijing's afternoon peak, when maximum daily temperatures typically occur.

Is Polymarket legal in my country?
