Recent forecasts show a cooling trend and increased precipitation likelihood for Guangzhou on August 31, shifting daily maximum temperatures toward the 32–34°C range near the long-term average high of 33°C after recent warmer days. Cloud cover and showers from an incoming weather system suppress solar heating during peak afternoon hours, with model differences in timing, intensity, and coverage creating the tight spread among leading outcomes. Higher probabilities for 33°C and 34°C reflect scenarios with partial clearing allowing brief warming, while 32°C aligns with more persistent rain. Updated runs from agencies like the China Meteorological Administration will clarify resolution criteria for the official daily high.
