Highest temperature in Shenzhen on July 16?

Platform comparison

Market context

Shenzhen is currently experiencing morning showers with a late thunderstorm expected, suppressing temperatures to a forecast maximum of 30°C (86°F) at Bao'an International Airport [1]. The crowd-implied probability for any outcome above the lowest range sits at 0% YES, reflecting a consensus that the incoming rain will prevent extreme heat. Historical data for mid-July in Shenzhen typically sees highs between 33°C and 36°C, making the current 30°C forecast an outlier driven by the active storm system rather than a seasonal shift [2].

The frontrunner in the market is the 29°C range at 38%, followed by 30°C at 29%, suggesting traders are pricing in a cool, wet day [4]. This represents a significant contrarian angle against the typical summer baseline, where temperatures rarely dip below 32°C. The primary catalyst to watch is the persistence of the thunderstorm late in the day; if the rain clears before the afternoon peak, temperatures could rebound sharply toward the historical average. Traders should monitor real-time updates on the storm's duration, as a premature exit from the cloud cover would invalidate the current low-temperature pricing and create immediate value in higher ranges [3].
