Traders assign the highest probability to a 38°C peak on August 9 in Guangzhou, followed closely by 37°C and 36°C, reflecting ensemble forecast spreads that center on 36–38°C. Subtropical high pressure is currently promoting mostly clear to partly cloudy skies, allowing strong solar insolation and surface heating in this humid subtropical climate where August averages hover near 33°C. Recent model runs show modest differences in cloud cover and low-level moisture that could trim or boost the daily maximum by 1–2°C, while urban heat island effects in the Pearl River Delta add a small upward bias. With only two days until resolution, updated guidance from the China Meteorological Administration and global models will likely tighten the distribution around these leading outcomes.
