Highest temperature in Beijing on July 28?

Platform comparison

Market context

Beijing's weather in late July typically sits in the high-temperature band, with the city experiencing peak summer heat during this period. Historical data from the Beijing Capital International Airport Station shows that late July temperatures regularly exceed 30°C, with extremes occasionally pushing toward 35–37°C depending on atmospheric conditions and whether monsoon systems bring cloud cover or sustained high-pressure ridges maintain clear skies.

The 0% crowd probability suggests traders are positioning for a specific temperature threshold that sits well above typical July maximums for the city. Comparable years provide context: July 2022 saw Beijing record a maximum of 35.2°C on the 13th, whilst July 2023 peaked at 33.1°C mid-month. The settlement mechanism relies on Wunderground's historical records from the airport station, which maintains consistent measurement standards and represents the official observation point for the metropolitan area. Traders should note that the exact threshold bands determine resolution—a market implying 0% probability indicates the crowd expects the day's high to fall outside the uppermost temperature range offered.

Catalysts affecting the outcome include the East Asian summer monsoon's positioning in late July 2026 and whether high-pressure systems dominate the region. The China Meteorological Administration issues 10-day forecasts that typically become reliable 5–7 days before the settlement date. Urban heat island effects around the airport, influenced by surrounding development and traffic patterns, can elevate readings 1–2°C above rural areas. Traders monitoring broader Northern Hemisphere weather patterns and seasonal anomalies should watch for any El Niño or La Niña signals that might shift typical summer circulation patterns.
