Current forecasts from regional meteorological models indicate Guangzhou will experience peak temperatures well above 28°C on May 16 amid typical early-summer subtropical conditions, with daytime heating enhanced by southerly flow and limited cloud cover. Historical May climatology for the region shows average highs near 29–31°C, and recent observational trends from the China Meteorological Administration confirm no significant cooling influence from northern cold fronts or heavy precipitation. Trader consensus at 100% for 28°C or higher reflects this strong alignment between model consensus and baseline seasonal norms. Only an atypical rapid shift in steering patterns or unexpected frontal passage could push the daily maximum below the threshold, though such developments remain outside current guidance.
