Best time to visit Taiwan: weather and seasons by month

Taiwan has two travel seasons rather than four. The dry, comfortable window runs from October into April, and the hot, wet, storm-prone window runs from May into September. The north and the south behave differently inside those windows, so the month you pick depends on where you are going.

Use the table as a starting point, then check the region you actually plan to visit: a grey drizzly week in Taipei can be a sunny week in Tainan at the same time.

The north-east monsoon decides winter. From October to March it parks drizzle over Taipei, Keelung, Jiufen and Yilan while the west and south stay dry and often sunny. If you are travelling in December or January, the south is the safer bet: Tainan and Kaohsiung are at their best, and Kenting is warm enough for the beach on a good day.

The east coast (Hualien, Taroko, Taitung) is the first place typhoons hit and roads can close after heavy rain. Its best months are April, May and November. The central mountains — Alishan, Sun Moon Lake, Hehuan, Yushan — are cool to cold at altitude, with frost and occasional snow on Hehuan in winter; mornings are usually clear and clouds build by noon, so plan sunrise starts.

The outlying islands have their own calendar. Penghu, Kinmen and Matsu are at their best in May and June; strong winter winds cancel boats and flights, and spring fog can ground Matsu and Kinmen flights. Green Island and Orchid Island follow the same summer pattern.

Taiwan does not swing as hard as Japan or Europe, but the peaks are real. February (Lunar New Year, dates move year to year) is the busiest and priciest stretch on the site's scale: trains and intercity buses sell out, many small restaurants and shops close for several days, and hotel rates jump. Big chains, malls and major sights mostly stay open.

July and August rate high on both crowds and price, with island ferries, Kenting and the east coast filling up. The medium-price, medium-crowd months are January, March, April, May, June, September, October, November and December — you trade some rain or heat for easier bookings and quieter sights. October and November are the sweet spot: good weather, medium prices, medium crowds.

Typhoons are the single biggest variable. The season runs roughly July to September, and a storm can shut transport island-wide for a day or two. Late typhoons are possible into early October. If you travel in that window, build slack into the itinerary and watch the Central Weather Administration forecasts rather than a long-range app.

The plum rains (late May to mid-June) bring steady wet days, heaviest in the north and west. They rarely stop travel, but they make mountain hikes and coastal days less rewarding. Winter in the north is drizzle rather than downpour: bring a light rain shell and shoes that cope with wet pavement, and plan indoor days in Taipei's museums and markets.

Air quality dips on still winter days in the west and south, most noticeably in Kaohsiung and Taichung. It is usually a haze rather than a health emergency, but travellers with asthma should check daily readings.

If your dates are fixed, match the region to the month rather than the month to the region. February, July and August are the months to avoid if you have a choice; November is the safest single answer for a first trip that covers Taipei plus one other area.

If you are choosing dates, aim for late October to mid-December or mid-March to late April. Both give you dry, mild weather across most of the island, medium prices and no holiday closures. Add three or more nights if you want the east coast or the south as well as Taipei.
