Latest numerical weather prediction models from Taiwan's Central Weather Administration and global ensembles indicate overnight lows in Taipei on September 25 will likely settle in the mid-20s°C range, driven by light easterly flow, moderate humidity near 80-90%, and limited radiative cooling under partly cloudy skies typical of late-September subtropical conditions. Model consensus shows minimal tropical moisture or frontal influence, keeping the minimum well above 20°C while unlikely to reach 30°C given the urban heat island and expected 23-26°C readings. Trader sentiment remains closely divided because short-range forecast uncertainty persists around exact timing of any scattered showers and subtle variations in boundary-layer mixing, with final high-resolution runs expected to narrow the range before resolution.
