Highest temperature in Beijing on July 6?

Platform comparison

Market context

On 6 July 2026, Beijing’s southern suburb observatory recorded a peak of 40.1°C at 13:15, representing the city’s official temperature for that day[1]. This real-world event directly contradicts the current Polymarket pricing, where the contract for “Highest temperature in Beijing on July 6” shows a 0% probability for the YES outcome, implying the market believes the temperature will not reach the specified threshold.

Historically, July in Beijing is the hottest month, with daily highs averaging around 31.1°C (88°F), rarely dropping below 25.6°C (78°F) or exceeding 35.6°C (96°F)[2]. In 2023, the city hit 40°C, and China has seen an increasing number of extreme heat days since 1961, with 4.1 days exceeding 35°C recorded this year alone[3][5]. These comparable cases suggest that a 0% probability is statistically misaligned with Beijing’s typical July climate.

Traders should monitor upcoming weather forecasts from Wunderground and official announcements from the Beijing Meteorological Bureau, as humidity levels and heatwave schedules can shift temperature outcomes rapidly[5]. Recent reports confirm China logged its hottest July since records began, with average temperatures reaching 23.21°C, reinforcing the likelihood of extreme heat in early July[8]. Conditional tokens on Polygon, settled in USDC, will reflect these on-chain adjustments as new data emerges.
