Recent official forecasts from the China Meteorological Administration and global numerical models indicate a daytime maximum of 31°C for Guangzhou on May 20, supported by persistent cloud cover, moderate moisture from the Pearl River Delta, and limited solar heating that caps convective warming. This positioning aligns with climatological May averages near 30–32°C while reflecting the latest model consensus that rules out stronger afternoon peaks. Trader consensus, backed by real capital, treats this as the most probable verified reading from the Guangzhou Baiyun station. A sudden shift to clearer skies or stronger subsidence could allow temperatures to exceed 32°C, though current atmospheric conditions make that outcome unlikely before the daily peak resolves.
