Taiwan Weather Guide - Best Time to Visit in 2026

The best time to visit Taiwan is autumn, October to early December: November is Taipei's driest month at 83.2 mm against 345.0 mm in June, and November typhoons average 0.11 a year against 0.95 in August. Month-by-month Central Weather Administration normals for Taipei and Kaohsiung, the plum rain and typhoon windows, and the best months for a health-screening trip.

Quick answer: The best time to visit Taiwan is autumn — roughly October to early December. November is Taipei's driest month in the Central Weather Administration's 1991–2020 normals (83.2 mm, against 345.0 mm in June), and typhoons reaching Taiwan in November average 0.11 a year against 0.95 in August. Spring (March–April) is the runner-up. This guide gives the official monthly numbers for Taipei and Kaohsiung, the plum-rain and typhoon windows, and the months we book screening trips into.

Taiwan's weather is more nuanced than "subtropical island, sometimes typhoons." The seasons feel genuinely different from north to south, and two specific windows on the calendar — plum rain in late spring, peak typhoon in late summer — can quietly derail a trip if you don't plan around them. This guide is for travelers, with a particular eye toward visitors timing a health-screening trip alongside tourism.

Every temperature and rainfall figure below is a Central Weather Administration monthly climate normal for the 1991–2020 period, station by station. If you want the geography first, see our overview of where Taiwan sits.

How does Taiwan's climate change from north to south?

Taiwan is small enough to cross by high-speed rail in an afternoon, but the north, the south and the mountains behave like different countries in winter.

The north — Taipei, New Taipei, Taoyuan, Hsinchu, Yilan — is cool and damp in winter and hot and humid in summer. Taipei's coolest month is January, with a mean daily maximum of 19.4 °C and a mean daily minimum of 14.2 °C; its hottest is July, at a 34.8 °C mean maximum. Taipei also records rain on 163.3 days a year, more than any other city in this guide.

The south — Tainan, Kaohsiung, Pingtung and the Hengchun peninsula including Kenting — barely has a winter. Kaohsiung's January mean maximum is 24.2 °C, and it records rain on 87.3 days a year against Taipei's 163.3. Hengchun, at the southern tip, averages 21.8 mm of rain in January — the closest Taiwan gets to a dry tropical beach season.

The mountains run far colder than the lowlands. Alishan's annual mean maximum is 15.8 °C against Taipei's 27.1 °C — roughly eleven degrees cooler. Higher still, Yushan's January mean minimum is −4.0 °C, which is why snow reaches the highest peaks most winters and closes mountain roads when it does.

The east coast — Hualien and Taitung — sits between those zones, with the central range blocking westerly systems. Hualien records 151.2 rain days and 2,034.5 mm a year against Taipei's 163.3 days and 2,329.5 mm, and its summers are milder than Kaohsiung's.

What is the weather like month by month?

Mean daily maximum and minimum temperatures below are CWA 1991–2020 normals for the Taipei and Kaohsiung stations.

Month	Taipei max / min (°C)	Kaohsiung max / min (°C)	Key features	Good for
January	19.4 / 14.2	24.2 / 16.2	Coolest month, often Lunar New Year	Hot springs, indoor culture, southern beaches
February	20.3 / 14.4	25.0 / 17.2	CNY peak, cherry blossoms begin	Yangmingshan blossoms, Pingxi lantern festival
March	22.7 / 16.0	27.0 / 19.7	Cherry blossoms peak, mild and dry	Health screening trips, hiking, sightseeing
April	26.4 / 19.3	29.3 / 22.8	Warm, mostly dry, Tomb Sweeping holiday	All outdoor activities
May	29.7 / 22.6	31.0 / 25.2	Plum rain (梅雨) starts mid-month; Taipei rain climbs to 239.9 mm	First half OK, second half rainy
June	32.7 / 25.1	32.1 / 26.3	Taipei's wettest month (345.0 mm); early typhoons possible	Indoor culture, museums, hot pot
July	34.8 / 26.6	32.7 / 26.7	Taipei's hottest month; typhoon season ramping	Beaches in Kenting, mountain escapes
August	34.2 / 26.4	32.1 / 26.3	Peak typhoon month, Ghost Month begins	Festivals, indoor attractions
September	31.5 / 25.0	31.8 / 25.9	Typhoon tail, Mid-Autumn Festival	Late month transitions to autumn sweet spot
October	27.6 / 22.4	30.1 / 24.4	Heat breaks; Taipei rain halves to 150.2 mm	Hiking, screening trips, all activities
November	24.8 / 19.7	28.1 / 21.6	Taipei's driest month (83.2 mm)	Best overall month for visitors
December	21.0 / 16.0	25.3 / 17.9	Cool in north, mild in south, holiday markets	Hot springs, indoor culture, screening trips

Two things fall out of the table. The north–south gap is smallest in summer — 34.8 °C in Taipei against 32.7 °C in Kaohsiung in July — and largest in winter, when Kaohsiung's January maximum runs 4.8 °C above Taipei's. And it is Taipei's rainfall, not its temperature, that makes or breaks a trip: 83.2 mm in November against 345.0 mm in June.

What is plum rain season (梅雨) actually like?

Plum rain (梅雨, méiyǔ) is the East Asian rainy season, caused by the boundary between Pacific and continental air masses parking over Taiwan for several weeks from mid-May into June. The normals show it plainly: Taipei's rainfall climbs from 152.5 mm in April to 239.9 mm in May and 345.0 mm in June, its wettest month of the year.

What it feels like on the ground: persistent grey skies, drizzle that turns to heavy rain on and off through the day, and humidity that makes air conditioning essential rather than optional. Temperatures aren't extreme — Taipei's May mean maximum is 29.7 °C — but the mugginess makes everything feel hotter and stickier.

Practical impact on travel: it does not shut anything down. Flights run normally, the high-speed rail (HSR) and Taipei Metro (MRT) are unaffected, and museums, restaurants, hot springs and shopping run on full schedule. What it ruins is outdoor sightseeing — Yangmingshan in plum rain is a foggy disappointment, Taroko Gorge becomes flood-watch territory, and the cherry blossoms have already finished by the time it starts.

What to pack: a compact travel umbrella (locals carry these year-round), waterproof shoes you can rinse off, and light moisture-wicking layers rather than cotton. Skip the rain jacket — it is too hot to wear in that humidity.

How risky is typhoon season?

Between 1911 and 2024 the Central Weather Administration counted 378 typhoons that made landfall on Taiwan or passed close enough to cause damage on land — an annual average of three to four. The headlines abroad make it sound apocalyptic; what actually matters to a trip is how those storms sit on the calendar.

Month	Typhoons invading Taiwan, 1911–2024	Average per year
April	1	0.01
May	9	0.08
June	25	0.22
July	98	0.86
August	108	0.95
September	91	0.80
October	33	0.29
November	12	0.11
December	1	0.01

August is the peak, July and September follow, and the risk collapses through October and November — 12 November storms in 114 years against 108 in August. What typically happens during a warning:

Flights: delays and rebookings during the storm window are common; extended multi-day groundings are rare.
HSR: may suspend service while red-flag winds last, then resume once the tracks are inspected.
MRT (Taipei subway): underground sections run almost always. Above-ground sections (Wenhu line, parts of the Tamsui line) may suspend during the worst hours.
Government typhoon day (颱風假): when wind and rain forecasts exceed thresholds, local governments call a "typhoon day" — schools and offices close, but most restaurants, convenience stores and hospitals stay open.

You will get warning, but not a trip's worth of notice. The CWA issues a sea warning 24 hours before a typhoon is forecast to affect the waters around Taiwan, and a land warning 18 hours before it is forecast to reach land. Buy travel insurance if you are traveling July to September, and keep the day either side of a fixed appointment free.

Is winter a good time to visit Taiwan?

Winter is the most underrated season in Taiwan, and one we regularly recommend for screening trips. The island splits neatly: the north turns into hot-springs season (Beitou, Wulai and Jiaoxi all hit their peak), and the south stays in t-shirt weather.

In Taipei, January averages 19.4 °C by day and 14.2 °C at night, with frequent grey skies and cold fronts that undercut those figures for a few days at a time. Locals overdress dramatically; a light fleece and a windbreaker handle it. The reward is the springs: Beitou's sulfur pools, Wulai's mountain baths and Jiaoxi's clear odorless water are all genuinely restorative when the air is cool.

In Kaohsiung and Kenting, December to February is the dry season — Kaohsiung's mean maximum holds between 24.2 °C and 25.3 °C across those three months, and its December and January rainfall totals are 19.2 mm and 19.1 mm. This is the time for beaches, boat trips to Liuqiu and the southern temple circuit. A chilly Taipei screening day followed by a warm Kenting recovery day is exactly the kind of trip-shaping move that makes winter work for medical tourism.

Lunar New Year (late January or February, depending on the year) is the one caveat. For about a week the country effectively closes — many restaurants shut, hotel rates spike and HSR seats sell out weeks ahead. Avoid the holiday week itself; the days either side of it are fine.

What is spring like, and when does plum rain start?

Spring is the season most travelers miss. February into mid-March brings cherry blossoms — Yangmingshan above Taipei, Wuling Farm in the central mountains and Alishan all peak in slightly different weeks. March and April are the driest warm months in Taipei, at 157.2 mm and 152.5 mm against 239.9 mm in May.

The trap is plum rain, whose onset shifts by a couple of weeks from year to year. If you are planning a spring trip, aim to be finished before the second half of May rather than betting on a specific date. Late March and April are the sweet spot — warm enough for shorts at Taipei maxima of 22.7 °C and 26.4 °C, cool enough for long hikes, and usually dry.

Spring is also when the central mountain roads (Hehuanshan, the Cross-Island Highway) reopen fully after winter and Taroko Gorge's waterfalls are at their best. Combine an early-April screening at a hospital partner with a few days of east-coast driving and you have used the calendar well.

How hot is a Taiwanese summer?

Hot, and relentlessly humid. Taipei's July mean maximum is 34.8 °C and its August mean minimum is 26.4 °C — the nights barely cool off. Relative humidity in Taipei averages 70.7 % in July, which is in fact its lowest monthly reading of the year against an annual average of 75.0 %. Walking from a metro station to a museum will leave you damp.

Locals adapt by structuring the day around indoors: late breakfasts, mid-day shopping, night-market dinners after the sun drops. Practical coping — stay near covered arcades (Taipei Main Station, Ximending, Zhongxiao East Road), schedule outdoor activity for early morning or evening, drink electrolytes more aggressively than you would at home, and use the indoor culture. The National Palace Museum, Eslite, Taipei 101 and dozens of department-store food halls were all designed around summer survival.

Where summer shines: Kenting beaches, where the sea breeze takes the edge off Hengchun's 32.1 °C July mean maximum; the high mountains, where Alishan's July mean maximum of 19.3 °C sits 15.5 °C below Taipei's; and Taipei's festival calendar, from Dragon Boat in June to Ghost Month rituals in August.

Why is autumn the best season?

Late September through November is when Taiwan is at its best, and the numbers say why. Taipei's rainfall falls from 315.2 mm in September to 150.2 mm in October and 83.2 mm in November, its driest month of the year. Daytime maxima ease to 27.6 °C in October and 24.8 °C in November. Typhoon frequency drops to an average of 0.29 in October and 0.11 in November.

This is hiking sweet-spot season. Yangmingshan's silver grass blooms in October. The Hehuanshan high road is at its scenic best with cool air and clean visibility. Taroko Gorge is dry enough that side trails reopen and the rivers run clear rather than muddy. Alishan's sunrise sea-of-clouds shows up more reliably than at other times of year.

Seasonal foods worth catching: pomelos around Mid-Autumn Festival, persimmons drying on rooftops in Hsinchu, Taiwan-grown apples from Lishan, and the year's first hot-pot menus appearing in November.

Combine late October or November with a screening and a few days on the east coast or in Tainan, and you have what most repeat visitors will tell you is the ideal Taiwan trip. See our 3/5/7-day itinerary suggestions for routing examples.

When is the best season to come for a health screening?

From a concierge perspective the question isn't "when is the weather nice" — it is "when is the weather least likely to disrupt a fixed-date hospital booking." A screening is scheduled weeks in advance, and a typhoon that grounds your flight on screening day costs you the appointment. On the CWA record, an August arrival meets an average of 0.95 typhoons against 0.11 in November.

Our recommended windows, in priority order:

October to early December (best overall). Taipei's lowest rainfall of the year, typhoon averages of 0.29 and below, and pre-Lunar-New-Year hotel rates. November is the single best month if you can pick one.
March to mid-April (second best). Stable spring weather, cherry blossoms as a bonus, no plum rain yet. Avoid the Tomb Sweeping holiday week in early April for hotel pricing.
Mid-December to mid-January (good with caveats). Cool but stable, hot-springs season, a December typhoon average of 0.01. Avoid Christmas through New Year for flight pricing, and avoid Lunar New Year week entirely.

Months we suggest avoiding for a screening trip: the second half of May into June, when plum rain soaks any outdoor recovery day planned around the appointment; August into mid-September, the typhoon peak; and Lunar New Year week, when hospitals run skeleton schedules and intra-Taiwan transit fills with holiday travelers.

Once the month is settled, the package is the other half of the plan. Our entry tier, Convenient, is $299 and fits into a single morning, which is why it suits a trip built around sightseeing; Essential is $699, and Premium is $1,699 for travelers who want imaging and a broader lab panel in the same visit. Booking the screening for the second or third day of the trip, rather than day one, gives you a buffer for both flight delays and jetlag.

For visitors combining medical and wellness, see our piece on why Taiwan is Asia's hidden wellness destination — the right month makes the recovery half of the trip work.

How bad is air quality in Taiwan?

Air quality varies by region more than visitors expect, and it varies by season in the opposite direction to the weather. The pattern: cleanest on the east coast (Hualien, Taitung), moderate in the north, worst in the southwest.

The Kaohsiung winter inversion is the headline issue. Through the cool months a stable atmospheric layer traps port, industrial and traffic emissions in the Kaohsiung basin — the same dry season that makes the south pleasant for beaches is what keeps the haze in place. Taipei sits in a basin too, and its worst stretches also arrive with winter cold fronts. Hualien and the east coast benefit from onshore winds and the mountain wall behind them.

Check before you plan rather than trusting a rule of thumb: the Ministry of Environment publishes live station-by-station readings on its Air Quality Monitoring Network. If you have asthma or are otherwise air-sensitive, put Kaohsiung in spring or autumn rather than winter, and route recovery days to Hualien.

One more environmental note: Taiwan sits on an active plate boundary and has frequent small earthquakes. They rarely affect travel, but read our earthquake preparedness primer before you arrive.

So when should you book?

November, if you can pick one month: Taipei's driest at 83.2 mm, with a typhoon average of 0.11. October and March–April are close seconds. December and January work well for screening trips combined with hot springs in the north and beaches in the south. Avoid the second half of May into June for plum rain, and August into mid-September for the typhoon peak.

If you're timing a Taiwan trip around a health screening, our concierge team can match your travel window to a specific screening package and partner hospital. The right month is the difference between a trip that runs smoothly and one that survives despite the weather.
