**Current forecasts for Taipei on September 16 point to an overnight low near 23–25°C under persistent northeasterly flow, moderate humidity, and variable cloud cover that limits radiative cooling.** Model consensus from sources such as the Central Weather Administration and international guidance shows daytime highs of 26–29°C transitioning to minimums typically reached in the early morning hours, with light drizzle or overcast conditions further moderating temperature drops. The closely matched market-implied probabilities around 24–25°C reflect this narrow forecast range, while lower outcomes like 19°C or below remain possible only if stronger winds or clearer skies enhance cooling beyond current guidance. Upcoming model runs and official updates will refine the exact minimum, as small shifts in wind speed or cloud timing can alter the low by 1–2°C. Historical September baselines for northern Taiwan support this range amid seasonal monsoon influences.
