Cool 12-23°C · Light rain · 20-30% cheaper than February · Cherry preview at Yangmingshan · Onsen weather at its best · Alishan's clearest sunrise season



Torn between January and February for Taiwan? January's quiet wins: hotels 20-30% cheaper than Lunar NY week, calm city, restaurants open, cool air makes long walks enjoyable, plus the cherry blossom preview at Yangmingshan mid- to late month.
Taipei and the north: 12-18°C, cool and humid with light fog, much less rain than summer (~80mm/month). Kaohsiung south: 18-23°C, milder. At Alishan, October–March = clearest skies of the year for sunrise and sea of clouds.
Five experiences that align especially with January
The Taiwan Cherry (山櫻花), a deep-pink early-blooming variety, flowers before Yoshino and Fuji types peak in late February. Mid- to late January at Yangmingshan: 30-60% bloom, no crowds.
January's cold (12-15°C) makes Beitou's outdoor pools feel perfect — body warm in 40°C water while cool air drifts in, sometimes with light valley fog. Public pools from NT$60, onsen hotels NT$800-2,000 per person.
2-3 weeks before Lunar NY (mid- to late January), Dihua Old Street (迪化街) turns into a holiday market — candied snacks, dried fruits, red lanterns. Festive buzz without the hotel price spike.
October–March is Alishan's clearest-sky season — best shot at sunrise and sea of clouds. Mountain 0-10°C, pack a down jacket. See how to reach Alishan; book lodging 1 month ahead.
Arrive Jan 1 and you'll catch NYE countdown at Taipei 101 — Asia's most iconic firework show, 5 minutes from the tower. Free viewing at Elephant Mountain and Xinyi district. Arrive 4-5 hours early.
