Highest temperature in Shenzhen on July 13?

Platform comparison

Market context

Shenzhen is experiencing heavy rain and cloud cover on 13 July 2026, with maximum temperatures forecast near 32°C rather than the extreme heat required for a “YES” outcome in this market. The crowd-implied probability sits at 0% YES, reflecting consensus that today’s wet, unstable conditions will suppress peak temperatures well below the thresholds needed to trigger a positive resolution.

Historically, July is Shenzhen’s hottest month, with average highs around 32°C (89°F) at Bao’an International Airport, though record peaks have occasionally exceeded 36°C under clear, dry skies [2][9]. The current 0% probability aligns with typical mid-July variability, but contrarian value could emerge if long-range models suddenly shift toward a prolonged heat dome—a rare but documented event in Guangdong during late summer. Recent global data shows July 2024 was the warmest July on record, yet local microclimates like Shenzhen’s airport station often remain moderated by coastal moisture and monsoon activity [5].

Traders should monitor the National Weather Service’s real-time observations for ZGSZ and Wunderground’s daily history updates, which serve as the official resolution source [7]. Any sudden announcement of a regional heatwave or a shift in the South China Sea monsoon pattern could alter temperature trajectories, though current forecasts from AccuWeather and Yr confirm rain and clouds persisting through the afternoon [6][10]. With settlement ending at 12:00 UTC today, the window for a dramatic temperature spike is effectively closed unless an unforecasted convective event occurs.
