Highest temperature in Beijing on July 25?

Platform comparison

Market context

Beijing's daily maximum temperature on 25 July 2026 will be recorded at the Capital International Airport meteorological station and resolved against historical weather data. The settlement mechanism relies on Wunderground's historical records for this specific location, which maintains consistent measurement protocols across years. July represents peak summer in Beijing, with typical daily highs ranging between 29–33°C, though heat waves can push readings above 35°C.

Historical precedent shows July temperatures in Beijing cluster predictably around seasonal norms. Over the past decade, extreme heat events—temperatures exceeding 37°C—occur roughly once every two to three summers, typically during mid-to-late July when atmospheric pressure systems stall over northern China. The 0% crowd probability suggests traders are pricing in confidence that the market's temperature bands exclude the most likely outcome, a common signal of miscalibration in weather markets where base-rate seasonal data dominates over tail-risk scenarios.

Traders monitoring this market should track China Meteorological Administration forecasts released in early July 2026, which provide 10–15 day outlooks for regional heat patterns. Programmatic approaches would benefit from integrating historical daily maxima from Wunderground's archive alongside real-time pressure and humidity indices from the Asian Pacific region. The settlement window closes at noon UTC on 25 July, meaning final readings must be confirmed before that timestamp; automated resolution bots should account for potential delays in Wunderground's data publication, which occasionally lags by several hours during high-traffic weather events.
