Forecast models from Taiwan's Central Weather Administration and international sources indicate a minimum temperature in Taipei on September 9 most likely between 23°C and 24°C, driven by strengthening northeasterly seasonal winds increasing cloud cover and limiting overnight radiative cooling amid humid conditions. Scattered showers expected across northern Taiwan further moderate temperature drops by enhancing atmospheric moisture and reducing clear-sky heat loss. These dynamics align with historical September baselines near 24°C lows while introducing model spread from variable wind speeds and precipitation timing. Upcoming CWA updates and refined ensemble runs will clarify whether marginal differences in cloud persistence tip the outcome toward 23°C or hold nearer 24°C.
