Recent forecasts indicate a high around 31–34°C for Shenzhen on August 28 amid weakening but still frequent thunderstorms, creating tight uncertainty across temperature bins. Subtropical monsoon conditions bring high humidity near 80–90% and convective activity that limits peak solar heating through cloud cover and evaporative cooling, with local model runs showing sensitivity to exact rain timing and intensity. Recent days of persistent showers have kept daily maxima near 30–32°C, aligning with climatological August averages yet allowing brief clearer periods for higher readings. Traders weigh official Shenzhen Meteorological Bureau updates and ensemble guidance on steering patterns that could shift the balance toward or below 32°C.
