Highest temperature in Shenzhen on July 23?

Platform comparison

Market context

Shenzhen is in the middle of its wet, humid midsummer period, and the market is really a question of whether the day peaks in the low 30s Celsius or gets pushed lower by cloud, rain and coastal convection. July averages in Shenzhen are around 31–32°C for daytime highs, with heavy humidity and frequent rainfall, so a very cool outcome is not the base case on climatology alone.[1][4][5]

That said, the crowd’s 0% yes price does not mean a zero-temperature outcome; it usually reflects either a thin market or the belief that the exact settlement band is highly unlikely. Historical July conditions in Shenzhen still leave room for temperatures to reach the low-to-mid 30s Celsius, with some sources noting potential highs near 33.7°C, which makes the upper bands materially more plausible than a sub-seasonal anomaly.[1][4][6]

For traders, the key catalysts are the day’s local weather trend, especially whether thunderstorms build over the Pearl River Delta and limit afternoon heating, and any shift in the forecast for cloud cover, rainfall or tropical moisture. The settlement source is the Shenzhen Bao'an International Airport station on Wunderground, so the market will depend on the station’s observed daily high rather than a citywide average; at 07:00 UTC, the main dependency is still how hot the afternoon gets after sunrise heating and before any rain bands arrive.[2][3]
