A strong cold air mass is expected to arrive tonight, bringing a change in weather and a drop in temperature, the Central Weather Administration (CWA) said.
The coldest time would be early on Thursday morning, with temperatures in some areas dipping as low as 8°C, it said.
Daytime highs yesterday were 22°C to 24°C in northern and eastern Taiwan, and about 25°C to 28°C in the central and southern regions, it said.

However, nighttime lows would dip to about 15°C to 16°C in central and northern Taiwan as well as the northeast, and 17°C to 19°C elsewhere, it said.
Tropical Storm Nokaen, currently east of the Philippines, is forecast to remain over the waters east of the country and poses no direct threat to Taiwan, the CWA said.
Starting today, conditions are expected to become more unsettled as the northeasterly system strengthens and moisture increases, raising the chance of rain along the northern coast and mountainous areas of Taipei and New Taipei City, it said, adding that areas north of Taoyuan and eastern Taiwan might also see brief showers.
The coldest temperatures are expected on Thursday morning, it said.
From Thursday to Saturday, there is a chance of snowfall on mountains above 3,000m, such as Hehuanshan (合歡山) and Hsuehshan (雪山), while areas at about 2,000m might see sleet or rime ice, it added.
From Wednesday through Friday, the cold air mass is likely to linger and reach the level of a “strong continental cold air mass,” defined as Taipei temperatures dropping below 12°C, independent meteorologist Daniel Wu (吳德榮) said.
Temperatures in low-lying areas could fall to as low as 8°C, he said.
The cold air mass is expected to weaken from Saturday, with daytime temperatures rebounding, but mornings and evenings remaining cool, Wu said.

CSBC Corp, Taiwan (台灣國際造船) yesterday released the first video documenting the submerged sea trials of Taiwan’s indigenous defense submarine prototype, the Hai Kun (海鯤), or Narwhal, showing underwater navigation and the launch of countermeasures. The footage shows the vessel’s first dive, steering and control system tests, and the raising and lowering of the periscope and antenna masts. It offered a rare look at the progress in the submarine’s sea acceptance tests. The Hai Kun carried out its first shallow-water diving trial late last month and has since completed four submerged tests, CSBC said. The newly released video compiles images recorded from Jan. 29 to
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) plans to make advanced 3-nanometer chips in Japan, stepping up its semiconductor manufacturing roadmap in the country in a triumph for Japanese Prime Minister Sanae Takaichi’s technology ambitions. TSMC is to adopt cutting-edge technology for its second wafer fab in Kumamoto, company chairman C.C. Wei (魏哲家) said yesterday. That is an upgrade from an original blueprint to produce 7-nanometer chips by late next year, people familiar with the matter said. TSMC began mass production at its first plant in Japan’s Kumamoto in late 2024. Its second fab, which is still under construction, was originally focused on
DETERRENCE EFFORTS: Washington and partners hope demonstrations of force would convince Beijing that military action against Taiwan would carry high costs The US is considering using HMAS Stirling in Western Australia as a forward base to strengthen its naval posture in a potential conflict with China, particularly over Taiwan, the Wall Street Journal reported on Saturday. As part of its Indo-Pacific strategy, Washington plans to deploy up to four nuclear-powered submarines at Stirling starting in 2027, providing a base near potential hot spots such as Taiwan and the South China Sea. The move also aims to enhance military integration with Pacific allies under the Australia-UK-US trilateral security partnership, the report said. Currently, US submarines operate from Guam, but the island could
EMERGING FIELDS: The Chinese president said that the two countries would explore cooperation in green technology, the digital economy and artificial intelligence Chinese President Xi Jinping (習近平) yesterday called for an “equal and orderly multipolar world” in the face of “unilateral bullying,” in an apparent jab at the US. Xi was speaking during talks in Beijing with Uruguayan President Yamandu Orsi, the first South American leader to visit China since US special forces captured then-Venezuelan president Nicolas Maduro last month — an operation that Beijing condemned as a violation of sovereignty. Orsi follows a slew of leaders to have visited China seeking to boost ties with the world’s second-largest economy to hedge against US President Donald Trump’s increasingly unpredictable administration. “The international situation is fraught
