Forecast models from sources including Open-Meteo and regional agencies indicate a daytime maximum near 35 °C for Guangzhou on October 13 under clear to mainly clear skies, light northerly winds, and negligible precipitation chance. Subtropical autumn conditions with high solar insolation and minimal cloud cover support strong surface heating, while recent observations show stable high pressure without significant moisture advection or frontal activity that could suppress peaks. Historical mid-October averages hover around 30–32 °C, making the current setup an above-normal but plausible outlier. Updated model runs through the morning of the 12th have kept 34–35 °C as the dominant range, aligning with the market-implied 59.5 % probability on 35 °C.
