Recent forecasts from multiple models, including those aligned with China's National Meteorological Center, point to a minimum temperature in Guangzhou on September 30 near 27–28°C under continued subtropical high pressure and southerly flow, with daytime peaks reaching 35–38°C. Persistent warm advection and high humidity have limited overnight radiative cooling compared to the 1991–2020 average low of 22.8°C for the date. Model consensus shows modest spread around this range, though scattered thunderstorms could locally enhance or suppress the minimum depending on timing and cloud cover. Trader balance between sub-22°C and 32°C+ outcomes reflects uncertainty in the precise overnight low amid evolving steering patterns and potential for minor forecast shifts before resolution.
