Highest temperature in Beijing on May 26?

Market context

Beijing's highest daily temperature on 26 May 2026 will be measured at Capital International Airport Station and resolved against historical weather data from Wunderground. The settlement window closes at midday UTC, requiring traders to monitor final readings before the cutoff. This market structure creates a practical exercise in real-time data integration: automated systems must poll Wunderground's historical archive, parse the daily maximum, and match it to the correct temperature band before the resolution deadline.

May temperatures in Beijing typically range between 25–32°C, with occasional peaks above 33°C during early heat waves. Historical May 26 data shows variability: the 2023 reading was 29°C, whilst 2022 recorded 31°C. The 0% crowd probability suggests either extreme confidence in a specific narrow range or insufficient liquidity across all brackets. Traders building conditional orders should reference the 30-year May average (approximately 28°C) as a baseline, then adjust for seasonal drift and any anomalous patterns in recent years.

China's meteorological service publishes five-day forecasts in early May, which traders can cross-reference against Wunderground's historical settlement methodology. Late May typically marks the transition into Beijing's warmer season, though subtropical systems remain unpredictable. Programmatic approaches should account for potential data delays on Wunderground's platform—historical corrections occasionally occur 24–48 hours after initial publication. Traders integrating this market into larger weather-derivative strategies should establish fallback verification sources and confirm timestamp precision, as the settlement window's noon UTC cutoff leaves minimal margin for data reconciliation.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
