Forecast models from sources including the China Meteorological Administration and international ensembles indicate a highest temperature near 30–31°C in Shenzhen on August 26, driven by widespread cloud cover, high humidity exceeding 80 percent, and frequent showers or thunderstorms expected through the day. These conditions limit solar heating and promote evaporative cooling, consistent with the typical late-summer monsoon pattern that caps daily maxima around the seasonal average of 31–32°C. Recent observations on August 25 showed afternoon peaks near 31°C amid similar instability, supporting trader emphasis on the 30–32°C range. Model spread in precipitation timing introduces modest uncertainty in the precise peak, with any earlier clearing potentially allowing a brief push toward 32°C.
