Persistent moist southwesterly flow and a broad low-pressure area continue to drive widespread showers and thunderstorms across northern Taiwan through August 23, maintaining high humidity and extensive overnight cloud cover that suppresses radiative cooling and keeps minimum temperatures elevated. Official guidance from the Central Weather Bureau and ensemble models consistently point to overnight lows near 25–27 °C, with the precise value hinging on the timing and intensity of convective bursts, local wind mixing, and any short-term shifts in cloud thickness. Historical August climatology for Taipei shows typical minima of 25–26 °C under similar regimes, while reduced rainfall or clearer breaks could allow slightly lower readings near 24 °C. The next round of high-resolution model updates and CWB briefings will refine these thresholds ahead of market resolution.
