Highest temperature in Shenzhen on August 6?

Platform comparison

Market context

Shenzhen’s forecast high for 6 August is clustered in the low 30s Celsius, with the market’s 0% YES implied probability effectively pricing in an outcome above the listed temperature band rather than the more typical August pattern. On the current read, the consensus sits around **31–34°C**, which is broadly in line with mainstream forecasts for the city and the Guangdong regional outlook showing Shenzhen at **26–34°C** for the same window.[6][7][9][13]

That is why the favourite remains the lower temperature ranges, while the only real underdog angle is a sharp midday surge if cloud breaks and rain stays away. Historical August framing still points to hot, humid conditions rather than extremes: Shenzhen’s August averages are around **31–32°C** by day, with lows near **26–27°C**, and multiple forecast sources flag showers or thundery conditions that can cap the day’s peak.[1][2][18][20] For handicappers, the value question is whether the market is over-discounting a brief hot spell; if the station gets a dry, sunny run through late morning and early afternoon, the upper end of the range becomes more live than a flat 0% would imply.

The main catalysts to watch are the day’s rain timing, cloud cover, and any thunderstorm bands moving through the Pearl River Delta, because those directly affect whether the airport station can touch its daily maximum before cooling starts. Current short-range guidance already leans humid with showers, and the Hong Kong Observatory’s Guangdong bulletin has Shenzhen at **26–34°C** with a generally fair-to-cloudy setup, which suggests the consensus is for heat but not necessarily a breakout spike.[3][6][13] In market terms, that leaves the favourite with the broader temperature bands and a contrarian case only if the latest hourly trend turns markedly drier and hotter.
