Highest temperature in Beijing on August 16?

Platform comparison

Market context

Beijing's highest temperature on 16 August 2026 will be measured at the Capital International Airport Station and resolved against Weather Underground's Daily Observations table. The crowd currently assigns zero probability to any outcome, suggesting either extreme confidence in a particular temperature band or insufficient liquidity to establish consensus pricing. August is Beijing's peak summer season, with historical highs typically ranging between 32–36°C, making extreme temperatures plausible but not exceptional.

Historical August records for Beijing show that mid-month temperatures rarely exceed 37°C, though heat waves have driven readings above 40°C in isolated years. The 0% implied probability across all ranges points to a market awaiting initial price discovery rather than reflecting genuine certainty about the day's weather. Traders should recognise that summer weather in northern China remains broadly predictable within seasonal bounds, yet the specificity of daily temperature resolution creates genuine uncertainty around which band will capture the actual high.

Catalysts for this market centre on real-time weather forecasting updates as August 2026 approaches. China Meteorological Administration forecasts and any issued heat warnings will inform expectations in the final weeks before settlement. The resolution mechanism—specifically Weather Underground's Daily Observations table rather than summary figures—introduces a technical dependency that traders should verify independently. Atmospheric pressure systems moving across northern China in mid-August will ultimately determine whether the day trends toward seasonal norms or breaks into less common territory.
