Recent forecasts from the China Meteorological Administration and supporting models project a daily maximum near 34–35°C in Guangzhou on August 29 amid widespread thunderstorms and high humidity typical of late-summer subtropical conditions. Afternoon heating before convective activity, combined with urban heat effects, supports the market’s emphasis on 36°C as the leading outcome while keeping 35°C and 37°C competitive. Thunderstorm timing and intensity introduce uncertainty in the precise peak, as localized clearing could allow brief excursions above model guidance. Historical August maxima in the region average near 33°C, providing context for why traders assign low probability below 34°C but remain cautious above 38°C given expected rain-cooled air. Updated model runs and official observations will refine these implied probabilities ahead of resolution.
