Highest temperature in Beijing on June 16?

Market context

On 16 June 2026, Beijing's highest temperature will be recorded at Capital International Airport Station and measured in Celsius. The market currently prices all temperature ranges at 0% probability on the YES side, indicating either a technical settlement issue or extremely thin liquidity across the conditional token buckets on Polygon. This disconnect suggests traders have not yet committed USDC collateral to establish meaningful price discovery for any specific temperature band.

Beijing's June climate sits at the threshold between late spring and early summer, with historical data from Wunderground showing typical highs between 28–32°C during this period. The 2025 June 16 reading reached 31.2°C; the previous year's equivalent day recorded 29.8°C. These precedents establish a reasonable baseline, though individual daily variation can exceed 3–4°C depending on cloud cover and wind patterns. The city's continental position means sudden warm fronts from the south occasionally push temperatures above 33°C, whilst cooler systems can suppress readings into the mid-20s.

Traders monitoring this contract should track China Meteorological Administration forecasts released in early June, which typically provide 10-day outlooks with reasonable accuracy for temperature ranges. Real-time atmospheric pressure systems moving across northern China in the week prior will signal whether a heat dome or cooler trough dominates. The settlement mechanism depends entirely on Wunderground's historical archive for ZBAA station, making data availability the critical dependency rather than forecast uncertainty itself.

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.
