Mercury Could Fall to 17°C in Northern Taiwan on Seasonal Winds: CWA

Taipei: Temperatures in northern Taiwan are forecast to fall as low as 17 degrees Celsius in the coming days with the arrival of this autumn's first northeasterly wind system, the Central Weather Administration (CWA) said Tuesday. CWA forecaster Tseng Chao-cheng indicated that the seasonal winds are expected to affect Taiwan from Wednesday through Friday, with northern Taiwan likely to feel the strongest impact.

According to Focus Taiwan, temperatures in the north from nighttime through early morning are forecast to drop to 17-20 degrees due to possible radiative cooling, which occurs when the ground cools under clear skies, light winds, and dry conditions. In central Taiwan, nighttime and early morning temperatures from Wednesday through Friday could range from 21 to 24 degrees, while in the south, they are expected to hover around 24-25 degrees.

Daytime highs are predicted to reach 30-32 degrees from Wednesday to Thursday before dropping by 1-2 degrees on Friday. Tseng noted that the approaching seasonal winds are likely to bring moisture to windward areas north of Taoyuan and eastern Taiwan, with heavier rainfall anticipated along the north coast and in the eastern counties of Yilan and Hualien on Friday.

The seasonal winds are expected to weaken over the weekend, but Greater Taipei and eastern Taiwan could experience brief showers, with sporadic showers possible in the south. Cloudy skies are forecast elsewhere over the weekend, with the possibility of afternoon showers. From Monday to Tuesday, the moisture is predicted to decrease as rainfall eases.
