The best months to visit Taiwan are November through January. Taipei's January averages a high of 18.4°C (65.1°F) with just 32.6mm (1.3in) of rain across 8 days — the driest month of the year by a wide margin. December is nearly as good at 21.9°C/15.9°C (71.4°F/60.6°F) and 56.2mm (2.2in), and November gives you 24.7°C (76.5°F) days if you want warmth without the summer's 35.1°C (95.2°F) peak.

All figures below are measured for Taipei in 2025. Taiwan is small but climatically split: the south (Kaohsiung, Kenting) runs warmer and drier in winter, and the east coast (Hualien, Taitung) catches more rain off the Pacific. Use Taipei as your baseline and adjust warmer as you go south.

The best months: November, December, January

This is the stretch where Taiwan stops fighting you.

January is the standout on paper. 32.6mm of rain over 8 days works out to about 4mm per rainy day — that is drizzle you walk through, not weather that cancels plans. Highs of 18.4°C (65.1°F) and lows of 12.2°C (54.0°F) mean a light jacket in the daytime and a proper one after dark. The catch is that 18.4°C indoors feels colder than it sounds, because most Taiwanese buildings have no central heating and the air is damp. Hotel rooms rely on wall-mounted air-con units running in heat mode.

December is arguably the better all-round month: 21.9°C (71.4°F) highs, 15.9°C (60.6°F) lows, 56.2mm (2.2in) spread over 13 days. More rainy days than January, but the same low intensity — roughly 4mm on each of those days. You get comfortable walking temperatures with no heat, which matters more in Taiwan than most places because so much of what you'd do here is done outdoors on foot: night markets, temple districts, the Maokong tea hills, coastal trails around Jiufen and Keelung.

November is the pick if you want to swim or head south. 24.7°C (76.5°F) days and 19.5°C (67.1°F) nights in Taipei, and 124.5mm (4.9in) over 14 days. That's double December's rainfall, but the daily intensity is still moderate at around 9mm per rainy day. Kenting and the southern beaches are still fully usable in November; by January they're pleasant but not swimming weather for most people.

Practical note on hot springs: Beitou, Wulai and Jiaoxi are at their best when the air is cold. December and January highs of 21.9°C and 18.4°C (71.4°F and 65.1°F) are exactly the conditions that make a 40°C outdoor pool worth the trip. In August at 35.1°C (95.2°F), the same pool is unbearable.

The months to avoid: July, August, October

Three months are genuinely difficult, for three different reasons.

July is the wettest in terms of frequency: 23 rainy days. That is roughly three days in four with measurable rain, alongside highs of 32.4°C (90.3°F) and lows of 25.4°C (77.7°F). But look at how the 248.3mm (9.8in) is distributed — about 11mm per rainy day. That's the classic Taiwanese summer pattern: hot, glaring morning, a violent convective downpour somewhere between 2pm and 5pm, then steam. It is not all-day rain. It is a daily interruption you plan around by scheduling museums, department stores and the MRT-connected parts of the city for the afternoon.

August is the heat problem. 35.1°C (95.2°F) highs and 25.7°C (78.3°F) lows — the hottest month of the year, and the overnight low never drops below body-comfort range. Rainfall is actually low at 65.5mm (2.6in) over 14 days, so if you only read the rain column August looks appealing. It isn't. Combine 35.1°C with Taiwan's humidity and outdoor sightseeing becomes a series of short hops between air-conditioned spaces. Taroko Gorge, Alishan trails and Yangmingshan hiking are all effectively off the table in the middle of an August day.

October is the outlier and the most misread month. Highs of 31.4°C (88.5°F), lows of 23.6°C (74.5°F), and 383.3mm (15.1in) of rain — the highest total of the entire year — across only 13 days. That works out to roughly 29mm on each rainy day, about seven times January's daily intensity. This is not scattered afternoon showers. This is typhoon-tail and northeast-monsoon rain: fewer rainy days than July, but each one capable of flooding streets and closing mountain roads. October is the month where "only 13 rainy days" is the most misleading statistic on the whole table.

May deserves a mention alongside them: 325.9mm (12.8in) over 17 days, the second-wettest total of the year, at 29.0°C (84.2°F). That is the plum rain (梅雨) season, and it is the sustained-drizzle kind rather than the burst kind.

Shoulder season: February, March, and September

September is the best-value month on this table and almost nobody treats it that way. It is still hot — 34.5°C (94.1°F) highs, 25.6°C (78.1°F) lows, barely cooler than August — but the rainfall figure is remarkable: 68.3mm (2.7in) over 17 days. That is about 4mm per rainy day, the lowest daily intensity of any month in the year, tied with January. Seventeen days with rain in September means brief passing showers that dry within the hour, not washouts. If you can handle mid-30s heat, September gives you summer conditions without the summer crowds and without July's 23-day rain frequency. The genuine risk is typhoons, which are unpredictable rather than scheduled — book flexible accommodation.

February is the cheapest-feeling of the cool months, with a caveat. Highs of 18.9°C (66.0°F) and lows of 13.1°C (55.6°F) — essentially January's temperatures — but 111.6mm (4.4in) over 15 days, more than three times January's rainfall. It's the grey, damp, drizzly end of Taipei's winter. The real complication is Lunar New Year, which falls in late January or February depending on the year: transport books out, many small restaurants and family-run shops close for a week, and prices spike. Check the date before you commit to February.

March is a real transition month: 22.6°C (72.7°F) highs, 14.6°C (58.3°F) lows, 216.4mm (8.5in) over 13 days. The temperature is close to December's, which is excellent, but the rain arrives in heavier bursts — around 17mm per rainy day. You get comfortable air and a decent chance of a soaked afternoon. Worth it if you want spring blossom season (Yangmingshan cherry blossoms, Alishan a little later) and can accept the trade.

April sits between March and May: 25.9°C (78.6°F) highs, 17.8°C (64.0°F) lows, 210.2mm (8.3in) over 17 days. Pleasant temperatures, but you are now getting rain on more than half the days of the month.

What each season actually means on the ground

Winter (December–February) — layers, not coats. At 18.4–21.9°C (65.1–71.4°F) daytime and 12.2–15.9°C (54.0–60.6°F) at night, you want a long-sleeve base, a fleece or sweater, and a light waterproof shell. No heavy coat. Pack a compact umbrella rather than a rain jacket for January and December — with 4mm on a typical rainy day, an umbrella is faster and you won't overheat under it. Your days look like: night markets without sweating through your shirt, full-day walking in Taipei's old districts, hot springs in the evening, mountain day trips that are genuinely comfortable.

Spring (March–May) — the wet ramp. Temperatures climb from 22.6°C to 29.0°C (72.7°F to 84.2°F) while rainfall climbs from 216.4mm to 325.9mm (8.5in to 12.8in). This is quick-dry clothing and a real rain shell, not an umbrella, because May's 19mm-per-rainy-day comes with wind. Shoes matter more than anything else you pack.

Summer (June–September) — plan the day around 3pm. Highs from 32.4°C to 35.1°C (90.3°F to 95.2°F), nights that never fall below 24.4°C (75.9°F). You will be changing shirts. The functional strategy is early starts (outdoor sightseeing before 11am), indoor afternoons, and evenings after 7pm when it's finally tolerable. Bring more shirts than days, sunscreen, and a packable poncho for the July downpours. Anything cotton stays wet.

Autumn (October–November) — two completely different months. October's 383.3mm (15.1in) demands a proper waterproof and a flexible itinerary; November's 124.5mm (4.9in) at 24.7°C (76.5°F) is close to ideal travel weather. Do not treat them as one season.

Month-by-month

• January — 18.4°C/12.2°C (65.1°F/54.0°F), 32.6mm over 8 days. Driest month of the year. Cool, crisp, best for hot springs and long walking days.
• February — 18.9°C/13.1°C (66.0°F/55.6°F), 111.6mm over 15 days. Same temperature as January, three times the rain. Check Lunar New Year dates.
• March — 22.6°C/14.6°C (72.7°F/58.3°F), 216.4mm over 13 days. Comfortable air, heavier rain bursts. Blossom season starts.
• April — 25.9°C/17.8°C (78.6°F/64.0°F), 210.2mm over 17 days. Warm and wet; rain on more days than not.
• May — 29.0°C/21.4°C (84.2°F/70.5°F), 325.9mm over 17 days. Plum rain season. Second-wettest month.
• June — 32.9°C/24.4°C (91.2°F/75.9°F), 146.5mm over 16 days. Heat arrives properly; humidity is relentless.
• July — 32.4°C/25.4°C (90.3°F/77.7°F), 248.3mm over 23 days. Most rainy days of any month. Afternoon downpour is near-daily.
• August — 35.1°C/25.7°C (95.2°F/78.3°F), 65.5mm over 14 days. Hottest month. Low rain doesn't rescue it.
• September — 34.5°C/25.6°C (94.1°F/78.1°F), 68.3mm over 17 days. Still hot, but the lightest rain per rainy day all year. Underrated if you tolerate heat.
• October — 31.4°C/23.6°C (88.5°F/74.5°F), 383.3mm over 13 days. Wettest month by volume, concentrated into few days. Avoid unless flexible.
• November — 24.7°C/19.5°C (76.5°F/67.1°F), 124.5mm over 14 days. Warm days, mild nights, manageable rain. Excellent all-rounder.
• December — 21.9°C/15.9°C (71.4°F/60.6°F), 56.2mm over 13 days. Second-driest. The best balance of temperature and dryness.

FAQ

What is the single best month to visit Taiwan?

December, for most people. Highs of 21.9°C (71.4°F) are warm enough for all-day walking without heat exhaustion, lows of 15.9°C (60.6°F) are mild for evenings, and 56.2mm (2.2in) of rain over 13 days is light enough that an umbrella covers you. January is drier at 32.6mm (1.3in) but colder at 18.4°C (65.1°F), which matters because indoor heating is uncommon. If you specifically want beach weather, take November instead — 24.7°C (76.5°F) highs.

Is Taiwan too hot in summer?

June through September run 32.4–35.1°C (90.3–95.2°F) during the day and never drop below 24.4°C (75.9°F) at night, with high humidity. It is workable but restrictive: you'll be doing outdoor activity before 11am and after 7pm, with air-conditioned afternoons in between. Hiking Taroko Gorge or Yangmingshan at midday in August's 35.1°C (95.2°F) is a genuinely bad idea. If summer is your only option, September is the smartest choice — nearly the same heat as August but only 68.3mm (2.7in) of rain spread thinly over 17 days.

When is typhoon season in Taiwan, and how much does it matter?

The risk window runs roughly July through October, and the data shows it clearly in October: 383.3mm (15.1in) of rain concentrated into just 13 days, about 29mm per rainy day — far more intense than any other month. A typhoon closes mountain roads, suspends the east-coast rail line and grounds flights, typically for one to two days. It doesn't ruin a two-week trip, but it can wipe out a four-day one. If you travel between July and October, book refundable accommodation and keep a flexible day in the itinerary.

Does it rain all day in Taiwan, or just in bursts?

It depends heavily on the month, and the rainy-day count alone will mislead you. Divide the rainfall by the number of rainy days: January (4mm), September (4mm), December (4mm) and August (5mm) all mean brief passing showers. July at 11mm per rainy day means a sharp afternoon downpour on most days that clears within an hour or two. May at 19mm and October at 29mm per rainy day are the months where rain genuinely takes over the day. So 23 rainy days in July is less disruptive than it looks, and 13 rainy days in October is far more disruptive than it looks.
