Taipei, Taiwan — February 1, 2026
Taiwan’s Central Weather Administration (CWA) reported that a combination of an eastward-moving cloud system from South China and a continental cold air mass is affecting weather conditions across the island on Saturday, bringing widespread rainfall and cooler temperatures, particularly in northern and central regions.
According to the CWA, areas from central Taiwan northward, including Yilan County, are experiencing extensive rainfall. Heavier showers are expected in parts of the Keelung North Coast, Yilan, and mountainous areas north of Taichung. Other regions across Taiwan are also seeing intermittent rain, prompting authorities to advise the public to carry rain gear when heading outdoors.
Temperatures remain on the cool side, with daytime readings in northern Taiwan and Yilan hovering between 13 and 16 degrees Celsius, creating a damp and chilly feel. In central and southern Taiwan, as well as eastern regions, overnight and early morning temperatures are expected to drop to around 14 to 18 degrees, while daytime highs range from 19 to 25 degrees. Residents are advised to dress warmly, especially during early mornings and evenings.
The CWA also noted that if temperature and moisture conditions align, there is a slight chance of isolated snowfall in high-altitude areas above 3,000 meters in central and northern Taiwan, as well as Yilan and Hualien. Travelers heading to mountainous regions are urged to watch for icy roads and slippery conditions.
In terms of air quality, conditions are generally favorable in the Zhumiiao area, Yilan, eastern Taiwan, as well as Matsu and Penghu, where levels are rated “good.” Northern and central Taiwan, along with Kinmen, are seeing “moderate” air quality, with isolated parts of central Taiwan reaching an “orange alert” level. Yunlin, Chiayi, Tainan, and the Kaohsiung-Pingtung region are also under an “orange alert” for air quality.
Looking ahead, the CWA said the continental cold air mass will continue to influence weather through early Tuesday (February 3). Northern Taiwan and the Yilan–Hualien area will remain cold, while other regions will experience cooler conditions during mornings and evenings. Moisture levels will stay relatively high, bringing brief showers to the Keelung North Coast, greater Taipei mountain areas, Yilan, eastern Taiwan, the Hengchun Peninsula, and parts of central mountainous regions.
From Tuesday daytime onward, the cold air mass is expected to weaken, allowing temperatures to gradually rise and rainfall to decrease. The eastern half of Taiwan may still see localized showers, with isolated rain possible along the Keelung North Coast, mountainous areas around Taipei, and the Hengchun Peninsula.
Forecasts for Monday and early Tuesday indicate low temperatures of 13 to 15 degrees in western Taiwan and Yilan–Hualien, 17 to 18 degrees in Taitung and Penghu, 11 to 12 degrees in Kinmen, and as low as 9 to 10 degrees in Matsu. Daytime highs are expected to range from 17 to 20 degrees in northern Taiwan, Yilan, Penghu, and Kinmen, while central and southern Taiwan and Hualien could reach 23 to 26 degrees.
From Wednesday (February 4) through Friday (February 6), most areas are forecast to see partly cloudy to sunny skies, with only isolated brief showers in Taitung and the Hengchun Peninsula. However, another weather system is expected to approach late Friday, with a frontal system passing through on Saturday (February 7), followed by a fresh surge of continental cold air that will likely bring another noticeable drop in temperatures, especially in northern and northeastern Taiwan.
Authorities continue to advise the public to monitor weather updates and take precautions against cold, wet conditions, particularly when traveling or heading into mountainous areas.
