Recent forecasts from meteorological agencies indicate Guangzhou's minimum temperature on September 25 will likely fall near 25–27°C under clearing skies after earlier showers, consistent with late-September subtropical norms where radiative cooling overnight competes with high humidity and residual cloud cover. Primary drivers include persistent southerly flow from the South China Sea maintaining warmth while any strengthening northerly influence or clearer conditions could allow greater nocturnal heat loss, pushing readings toward the low 20s. Conversely, sustained cloudiness or weak frontal passage would limit cooling and support minima near or above 28°C. With model consensus tight around 26°C but short-range variability possible from timing of any final rain bands, trader sentiment reflects this narrow uncertainty band rather than extremes.
