Highest temperature in Beijing on July 16?

Platform comparison

Market context

Beijing’s highest temperature on 16 July 2026 will be recorded at the Beijing Capital International Airport Station, with the market resolving to the Celsius range containing that peak. The current crowd-implied probability for any specific outcome is 0% YES across the board, yet Polymarket data shows a clear frontrunner: 33°C at 39%, followed by 34°C at 27%[1]. This divergence between the flat 0% YES and the concentrated odds on 33–34°C suggests the market is pricing a narrow band rather than a binary event, a nuance often missed when comparing cross-platform lines.

Historically, July in Beijing is one of the wettest months, averaging around 185 mm of rainfall, which typically moderates peak temperatures[2]. Comparable cases from recent years show mid-July highs clustering between 31°C and 35°C at ZBAA, making the 33–34°C range statistically plausible. The 0% YES probability likely reflects a misunderstanding of the market’s multi-outcome structure rather than a genuine belief that no temperature will be recorded, highlighting a key discrepancy between prediction-market implied probability and how traders interpret sportsbook-style binary lines.

Traders should monitor daily weather bulletins from the China Meteorological Administration and real-time updates on Wunderground, the official resolution source, for the day’s peak reading[1]. No specific announcements or schedules are pending, but the dependency on Wunderground’s daily history page means any data lag or station anomaly could affect settlement. Analyst consensus, inferred from the 39% and 27% odds, points to 33°C as the most probable outcome, a line that diverges from the flat 0% YES implied by the binary framing on some platforms.
