Taiwan in January

Damp, cool spells dominate much of January in Taipei and Keelung; the northeast monsoon brings persistent drizzle and gray skies that make the city feel colder than the thermometer says. Taipei’s old streets and night markets stay busy despite the wet, but you’ll want a waterproof jacket and umbrella-sweaters and a light down jacket are handy for evenings. Mountain foothills like Yangmingshan often sit under low cloud and can be icy on windy days, while Yilan on the northeast coast can be windblown and rough seas may cancel ferry runs.

January often feels mild compared with the north: Taichung’s days hover around the mid-teens Celsius and dampness is less persistent than Taipei, making city wandering comfortable if you have a light jacket. Inland spots like Sun Moon Lake are cool in the mornings and excellent for brisk bike rides before crowds arrive-fewer wet days mean clearer lake views. Rural markets are lively during Lunar New Year travel, so reserve accommodation early if you want to visit the lake or Alishan transit points.

January in Kaohsiung and Tainan is mild and often pleasantly warm compared with the north-daytime highs commonly sit in the high teens to low 20s°C, making temple-hopping and night markets enjoyable. Kenting on the southern tip is usually balmy and sunny, ideal for beach walks and snorkeling but evenings can be cooler near the coast. Crowds are smaller than in summer except around Lunar New Year, when domestic travel spikes and hotels in Kenting may book out.

January here is cooler than the south but milder than the north; Hualien’s days are often cool and sunny, while the Taroko Gorge can feel raw in the wind with occasional cold drizzles. Coastal roads can be exposed to northeasterly swell and ferry services to offshore islands may be altered by rough seas. It’s a good month for quieter hikes in Taroko-expect dramatic, moody skies and bring a warm waterproof layer.

January in the high mountains means cold, often near-freezing nights and the real chance of snow on higher passes like Hehuanshan and Yushan approaches during strong cold snaps. Road crossings such as the Hehuan Road can close after snowfall and ice-carry warm layers, crampons for treks if you plan to go high, and check mountain road bulletins. Lower mountain hamlets like Alishan are popular for their sunrise trains and can be busy when snow or frost makes for dramatic vistas.
