Current forecast models from sources like the China Meteorological Administration and international ensembles project Guangzhou's highest temperature on April 18 at 31–32°C, reflecting trader consensus in the closely matched leading outcomes amid partly cloudy skies and a stray thunderstorm risk. This follows recent Guangdong highs in the upper 20s to low 30s°C during an above-normal warm spell, with April 17 expected to bring cooling rain and thunderstorms before rebounding under weak high-pressure influence. Compared to historical April averages of 26–28°C at Baiyun International Airport—the market's resolution station—subtle differences hinge on cloud cover timing, afternoon solar heating, and convective activity, with new model runs daily potentially tipping the balance toward 30°C or 33°C outliers.
