Recent moisture from typhoon outer bands and a lingering low-pressure system has sustained cloud cover and scattered showers across northern Taiwan, limiting daytime heating in Taipei ahead of September 6. Central Weather Administration guidance and ensemble forecasts indicate highs most likely between 29–32 °C under partly to mostly cloudy skies, with afternoon convection possible. Persistent humidity near 80–90 % and northwest flow further moderate peak temperatures relative to the September climatological average of ~31 °C. Model spread centers on whether brief clearing allows a 32 °C reading or sustained rain caps it at 30 °C, producing the tight market clustering around 30–32 °C. Updated CWA guidance and afternoon convection trends on September 5 will provide the next key signal for resolution.
