Current forecast models from agencies like the China Meteorological Administration point to overnight lows of 24–26°C in Shenzhen on September 2, driven by persistent high humidity near 80–90%, extensive cloud cover, and moderate northerly winds that reduce radiative cooling under subtropical monsoon conditions. These factors explain the tight clustering around 23–25°C in trader sentiment, with small differences arising from variations in precipitation timing, wind gusts, and urban heat retention that models resolve differently. Historical September baselines near 24°C provide context, while any late-model shifts in steering patterns or clearer skies could nudge the minimum lower. Updated runs and local observations will refine resolution criteria ahead of market close.
