Forecast models from sources including the China Meteorological Administration indicate a daily maximum of 29–31°C in Shenzhen on October 2, with scattered showers and cloud cover expected to limit solar heating and cap peak readings. Current October 1 highs near 32–34°C reflect clearer conditions, while the approaching moisture and easterly flow will increase humidity and reduce insolation, differentiating the closely matched 30°C and 31°C outcomes. October climatology shows typical highs around 29°C amid the post-monsoon transition, supporting trader focus on these thresholds over higher or lower extremes. Updated model runs and official briefings tomorrow morning will refine resolution probabilities ahead of market close.
