Highest temperature in Beijing on July 16?

Platform comparison

Market context

Beijing faces a mid-July heat check on 16 July 2026, with the Beijing Capital International Airport Station set to record its peak daily temperature. The market currently implies a 0% probability for any outcome below the seasonal norm, yet short-range ensemble forecasts point to modest afternoon heating near typical July levels, making the 32–34°C range the clear favourite [1]. Traders are pricing in 33°C as the frontrunner at 39%, followed by 34°C at 27%, suggesting the consensus expects a warm but not extreme day [1].

Historically, mid-July highs in Beijing cluster tightly around 33°C, with deviations beyond 35°C rare unless a persistent southerly flow traps moisture and heat. The current 0% implied probability for lower ranges appears overconfident, as boundary-layer mixing and insolation variability can easily push outcomes to 31–32°C, creating a potential underdog value spot for contrarian traders [1].

Key catalysts include the 12:00 UTC settlement deadline and real-time updates from Wunderground, which will publish the official highest temperature for the day [1]. Traders should monitor the gear-icon temperature setting on the Wunderground history page to confirm Celsius readings and watch for any late revisions before the first datapoint for 17 July is published, as post-12:00 UTC adjustments will not be considered [1].
