Weather in Taiwan: An overview
Taiwan is split between two distinct climate zones. Northern Taiwan lies within a sub-tropical zone while Southern Taiwan sits within the tropical zone along with its close neighbour Hong Kong. The differences between the two regions are usually not huge, certainly nothing like the variation you’ll find in nearby Japan or Korea.
Most of Taiwan is warm year-round with mild winters and hot summers. But warmth is not the issue here.
The real problem with weather in Taiwan is typhoon season, often lasting from July until September. You’ve probably witnessed some epic Taiwanese typhoons on your local news channel. This is exactly the type of weather you want to avoid when planning your trip to Taiwan!

The verdict: When is the best time to visit Taiwan?
The best month to visit Taiwan is either November or April.
Why Visit Taiwan in November?
With the extreme heat of summer and rainy season long gone, visiting Taiwan in November is a brilliant option. On average, November is the driest month (tied with December), and warm, comfortable temperatures still remain throughout Taiwan.
November is one of the best times of the year to experience places like Yangmingshan National Park where the fall colours are out in full force. It’s also a far more comfortable month for urban explorers and for escaping Taipei on a day trip. Taiwanese cities like Taipei and Kaohsiung can get oppressively hot (and wet) in summer, so November is a welcome change!
Perhaps the biggest advantage to visit Taiwan in November is the lack of crowds. Finding flight deals to Taipei and discounted accommodation will be much easier. Who knew that choosing the best time to visit Taiwan could also save you money?
Why Visit Taiwan in April?
If you can’t travel in November, visiting Taiwan in April is the next best alternative. The earlier in April you can make it the better, as rainfall starts to creep up towards the end of the month.
Heading into late spring, the temperatures in Taiwan are starting to warm up, making it a comfortable trip without the extreme heat of a Taiwanese summer. By April, the spring bloom is also in full swing. Along with May, April’s the most colourful time to travel around Taiwan!
Despite all its perks, however, April falls in Taiwan’s high-tourist season. Flights to Taiwan will be harder to come by (mainland Chinese will be flocking here by this time) and accommodations will book up quickly. Visiting in Taiwan in April may involve tight travel planning and a slightly beefier travel budget.
