Current forecast models from sources including the Met Office and regional analyses indicate a daytime high near 31°C for Guangzhou on October 4 amid humid conditions, scattered thunderstorms, and light variable winds that limit daytime heating. Trader consensus favoring 32°C over 31°C or 33°C reflects uncertainty in cloud-cover timing and rainfall intensity, which can suppress or permit brief peaks above the 30.4°C climatological average. Model spreads arise from differences in steering flow and moisture convergence, with resolution hinging on whether convection allows surface temperatures to edge higher before afternoon showers develop.
