What is the weather like in Taiwan in 2026?

The north has a clear cool season. From roughly December to February, Taipei turns damp and overcast as the northeast monsoon pushes moist air against the hills around the Taipei basin, so winter feels colder than the thermometer suggests. The south skips most of that: Kaohsiung and Tainan keep mild, sunny, mostly dry winters, which is why many movers who hate grey skies drift south. Spring brings the mei-yu, or plum rains, a wet stalled front that usually settles in around May and June before the full heat arrives.

Summer from June to September is hot and humid everywhere on the plains, with highs often in the low to mid 30s C and a much higher feels-like near the coast. This is also the core of the typhoon window, which runs roughly July to October and can deliver several storms in a typical season rather than a fixed count you can plan around. Autumn, once the last storms clear, is the stretch many locals rate as the most comfortable.

Taipei's basin shape traps heat in summer and moisture in winter, so its ventilation and rain rhythm differ from anywhere else on the island: see Living in Taipei. Taichung, on the western plain, markets itself on a milder, drier feel between the two extremes and often dodges the worst of both the northern damp and the southern peak humidity: Living in Taichung. Kaohsiung trades cool winters for a long warm season and strong sun: Living in Kaohsiung.

Altitude flips the whole picture. Hill towns and the high-mountain areas around Alishan and the Central Range stay far cooler than the coast year round, which is why tea country and cool-weather escapes exist a short drive from steamy cities. If heat is your main worry, elevation matters as much as latitude.

Weather here hits your home and your bills. Damp northern winters and sticky summers both push mould and heavy air-conditioning use, so a dehumidifier is normal kit and cooling drives the summer electricity bill: Utilities, internet and transport.
