**Recent northerly winds associated with a strong cold air outbreak are the main driver moderating Shenzhen’s daytime highs for October 5, shifting trader focus toward the 28–30 °C range.** Official guidance and model consensus indicate partly cloudy skies with highs near 28–30 °C after several days of 30–32 °C readings and widespread rain. The cooler, drier air mass reduces surface heating and cloud cover allows for modest diurnal warming, while any lingering moisture or variable wind speeds could nudge the peak slightly higher or lower. This produces the tight clustering around 28 °C (22.5 %), 29 °C (31.0 %), and 30 °C (24.5 %), with lower probabilities assigned to 31 °C+ outcomes that would require stronger insolation or delayed frontal passage. Updated model runs and local observations over the next 48 hours will be the key catalysts for further market movement.
