Current forecasts from models including GFS and ECMWF indicate Guangzhou highs of 35–37°C on September 29, 2026, driven by persistent subtropical high pressure, light southwesterly winds, and high humidity limiting overnight cooling. These conditions support daytime heating above the late-September climatological average of roughly 31°C. Recent model runs show limited spread, with peak temperatures most likely in the 36–37°C range under mostly clear to partly cloudy skies and minimal precipitation. Trader consensus reflected in the leading 36–38°C outcomes aligns with this consensus, while lower-probability tails account for possible model shifts or localized cooling from brief cloud cover ahead of the resolution window. Updated forecasts from official agencies will refine these probabilities in the next 48 hours.
