The Taiwan Central Weather Bureau has forecasted that starting from the evening of the 26th, a cold air mass will move southward, bringing colder temperatures to various regions. From the night of the 27th through the early morning of the 29th, as the cold air mass envelops Taiwan, temperatures in northern Taiwan could drop to as low as 8 degrees Celsius. By the first day of the Lunar New Year, the influence of the cold air mass will weaken, but on the 1st of February, another cold air mass from the mainland will arrive, causing temperatures to drop across different areas.
Over the next 10 days, the Taiwan Central Weather Bureau’s weather forecast predicts that on the 25th and 26th, the northeast monsoon will bring increased moisture, leading to prolonged periods of rain in areas such as Keelung’s northern coast, Yilan, and the mountainous regions of Greater Taipei. There is a probability of localized heavy rain, while other areas may experience brief showers. Temperatures on the 25th and 26th are expected to range from 14 to 19 degrees Celsius in the north and northeast, 14 to 24 degrees Celsius in central Taiwan, 15 to 26 degrees Celsius in the south, and 17 to 22 degrees Celsius in Hualien and Taitung.
The Taiwan Central Weather Bureau also forecasts strong winds and high waves on the 25th and 26th, especially in open coastal areas from Taoyuan to Tainan, along Keelung’s northern coast, the Hengchun Peninsula, and outlying islands such as Lanyu, Green Island, Penghu, Kinmen, and Matsu, where gusts could reach 8 to 9 on the Beaufort scale and waves could soar to approximately 2 to 3.5 meters.
As the Chinese New Year holiday approaches, a 9-day holiday period in Taiwan will begin on the 25th. The Central Weather Bureau warns that from the evening of the 27th (Chinese New Year’s Eve) to the early morning of the 29th (the first day of the Lunar New Year), the cold air mass will bring extremely cold weather to various regions. However, by the daytime of the 29th, the cold air mass will weaken, allowing temperatures to gradually rise. The weather will still be chilly in the mornings and evenings, with significant day-night temperature differences. On the 27th, there will be some moisture affecting parts of the north, east, and central-southern mountainous regions, resulting in localized brief showers; other areas will be mostly cloudy.
From the 27th to the 29th, temperatures are projected to range from 8 to 19 degrees Celsius in the north and northeast, 10 to 20 degrees Celsius in central Taiwan, 12 to 22 degrees Celsius in the south, and 12 to 19 degrees Celsius in Hualien and Taitung. Wind and wave conditions on the 27th to the 29th will feature strong northeasterly winds, with gusts hitting 9 to 10 in exposed coastal areas from Miaoli to Tainan, the eastern coast, the Hengchun Peninsula, Lanyu, Green Island, Penghu, and Matsu having waves of about 3 to 4.5 meters.
On the 30th (the second day of the Lunar New Year), radiative cooling effects will lead to cold mornings and evenings across Taiwan, with relatively large day-night temperature differences. The day will be mostly cloudy to sunny, with only scattered brief showers expected in the eastern region. Temperatures on the 30th are forecasted to range from 10 to 22 degrees Celsius in the north and northeast, 11 to 23 degrees Celsius in central Taiwan, 13 to 24 degrees Celsius in the south, and 14 to 21 degrees Celsius in Hualien and Taitung. Wind and wave conditions on the 30th will continue to diminish, with the Hengchun Peninsula experiencing relatively strong gusts and waves reaching around 1 to 1.5 meters.
Furthermore, on the 31st (the third day of the Lunar New Year), mornings and evenings across various regions will be cooler, with significant day-night temperature differences in the western regions. Most areas will experience partly cloudy to sunny skies, with occasional scattered brief showers only in the eastern region. On the 1st of February (the fourth day of the Lunar New Year), as a weather front passes through and cold air masses descend from the mainland, temperatures will drop across different regions. Localized brief showers are expected in the north, east, and central-southern mountainous regions, while other areas will be mostly cloudy.
Additionally, on the 2nd of February (the fifth day of the Lunar New Year), influenced by the cold air mass from the mainland, the weather will be colder in the north and northeast, with other regions also experiencing chilly mornings and evenings. Localized brief showers are expected in the north and eastern regions, while the rest of Taiwan will be mostly cloudy. There is a need to be cautious of localized low clouds or fog affecting visibility in the western regions and outlying islands when the weather warms up or when a weather front approaches. The timing and intensity of later cold air masses and weather fronts remain uncertain; therefore, it is advisable to stay updated on the latest weather information from the Taiwan Central Weather Bureau.
