Recent official forecasts from sources including the China Meteorological Administration and global models indicate persistent cloud cover, high humidity, and widespread thunderstorms over Guangzhou through August 25, driven by tropical moisture and weak steering flows. These conditions typically suppress nocturnal radiative cooling, supporting overnight lows near the 25–27°C seasonal norm rather than extreme deviations. Trader sentiment remains closely balanced between sub-22°C and 32°C+ outcomes because model runs show minor timing differences in rain bands that could either enhance cooling or maintain elevated dew points, while historical records (lowest 22°C in 2015) underscore the narrow margin for resolution. Updated NMC guidance expected within 24 hours will likely narrow the range.
