Taiwan’s weather for retirees presents unusual challenges as it is uniquely diverse, shifting from subtropical in the north to tropical in the south, strongly influenced by the Asian monsoon system and its mountainous spine. For foreign retirees, understanding these distinct regional and seasonal patterns is key to a comfortable life!
The Year-Round Humidity Challenge
No matter where you settle, high humidity is a constant feature of life in Taiwan, averaging between 75~85% all-year-round. This is perhaps the biggest adjustment for newcomers. High humidity can make the summer heat feel oppressive and the winter coolness feel damp and penetrating. It also requires attention to indoor mold and the protection of electronics and belongings. Air conditioning and dehumidifiers are not luxuries; they’re essential tools for comfort and home maintenance.
North vs. South: A Tale of Two Monsoons
Taiwan’s weather is sharply divided between its northern and southern halves, especially in winter:
Northern Taiwan (Taipei, Keelung, Yilan): The winter (December to March) is dominated by the Northeast Monsoon. This means cooler, persistently cloudy, and often drizzly weather. Average high temperatures hover around 18–21°C (65–70°F), but the dampness makes it feel colder. Summers are hot, oppressive, and wet, with high temperatures averaging over 32°C (90°F).

Southern Taiwan (Kaohsiung, Tainan, Kenting): The South enjoys a distinct dry winter. While the North is gloomy, the South is often sunny and mild, with average high temperatures near 24°C (75°F). The seasonal rainfall pattern is reversed: nearly all precipitation falls during the extremely hot, muggy summer, primarily due to the Southwest Monsoon and typhoons. This region is known for more sunshine hours annually.
Central Taiwan (Taichung): Often considered to have the most favorable climate, Taichung generally experiences milder winters than the North and receives less total rainfall than either the North or South, leading to more clear days.
Seasonal Considerations
Spring (March to May): A transition period often bringing the “Plum Rain” season (late spring/early summer). This can involve a period of persistent, heavy rain and is another time when humidity peaks.
Summer (June to September): The longest season, characterized by intense heat, high humidity, and frequent afternoon thunderstorms. Average high temperatures are well into the 32°C+(90s°F), with perceived temperatures often exceeding 38°C (100°F).
Typhoon Season (May to November, peaking July to September): Taiwan is on the path of Pacific typhoons, which can bring extremely heavy rain, strong winds, and flooding, leading to government and business closures on “Typhoon Days.” While direct hits aren’t constant, residents must be prepared for annual disruptions. Staying informed via local weather alerts is crucial.
Autumn (October to December): Generally the most pleasant season island-wide. Skies are clearer, humidity drops slightly, and temperatures are comfortable. This is widely considered the best time for outdoor activities and travel.
Mountain Regions: Taiwan’s central mountain range offers a temperate climate zone. Temperatures drop significantly with altitude, providing a natural escape from the summer heat and even seeing occasional snow on the highest peaks in winter.
Taiwan’s weather for retirees: Summary
In summary, choosing your retirement locale in Taiwan significantly impacts your daily weather experience. Retirees seeking bright, mild winters often favor the South, while those in the North should prepare for a damp, gray winter.
Regardless of the region, managing the ubiquitous humidity and preparing for typhoon season are essential parts of adjusting to Taiwan’s unique annual rhythm.
