Current forecasts for Guangzhou on October 13, 2026, from multiple models show a peak afternoon high near 34–35°C under clear to mainly clear skies, light northerly or variable winds under 10 km/h, and negligible precipitation risk. These conditions support strong daytime solar heating in the subtropical autumn environment without significant cloud cover or frontal systems to moderate temperatures. Official guidance and ensemble outputs align on this range, with some hourly projections briefly touching 35°C while others cap at 33–34°C. This scientific consensus underpins the market's heavy weighting toward 35°C as the daily high, with secondary support for 34°C or 36°C reflecting minor model spread and typical observation uncertainty at official stations. Real-time surface data through the afternoon will determine the precise maximum.
