Recent forecasts from Chinese meteorological sources and international models indicate persistent moderate rain and cloud cover over Guangzhou on October 3, with expected highs of 30–31°C. This follows a sharp cooldown from October 1 highs near 34–35°C as a frontal system brings widespread precipitation, limiting solar heating and promoting evaporative cooling. Historical October averages hover around 30.5°C, but active rain and high humidity (often exceeding 80%) typically cap daytime peaks below clear-sky potential. Model consensus remains tight around these values, though minor shifts in timing or intensity of showers could push the observed maximum toward 32°C or hold it at 30°C. Updated guidance from the China Meteorological Administration and global ensembles will refine this ahead of market resolution.
