Current short-range forecasts from multiple models indicate a daily minimum near 24°C for Guangzhou on September 3, consistent with climatological norms of 24–25°C amid typical late-summer subtropical conditions. Trader sentiment remains split between the 19°C-or-below and 29°C-or-higher outcomes at equal 34.5% implied probability due to lingering uncertainty over steering patterns, cloud cover, and any residual moisture from western Pacific systems that could enhance nighttime radiational cooling or suppress it via increased humidity and light winds. Key differentiators include the strength of northerly flow behind the subtropical high, which promotes clearer skies and greater diurnal range, versus southeasterly monsoon influences that raise overnight lows through added cloudiness and precipitation. Updated model runs and official guidance from regional meteorological centers will likely narrow these ranges as the date approaches.
