Climate and Weather of Tainan, Taiwan

The climate of Tainan

Tainan is the oldest city in Taiwan. Of course, the region had been inhabited much earlier, but it was the Dutch who laid the foundation for what we now know as Tainan. During the colonial era, the VOC built Fort Zeelandia here between 1624 and 1634. This fortification ensured that the Dutch ruled here until 1662. Then they were defeated by a huge force of the Chinese led by Koxinga. Tainan became the capital of Taiwan, until that role was taken over by Taipei. Tainan’s rich history has ensured that there are many fascinating sights to see and that the city can be counted among the top tourist destinations in Taiwan.

According to Bridgat, Tainan has a tropical monsoon climate, which is classified as an Am climate within the Köppen-Geiger climate system. Some sources will say that Tainan has a china climate (Cwa climate). That was true, but due to climate change , Tainan recently no longer meets the criterion that the coolest month has an average daily temperature between -3 °C and 18 °C. The coolest month (February) nowadays has an average daily temperature of 18.2 degrees. In the last century it was just below the limit of 18 degrees.

It is best to travel to Tainan during the winter season. Then the temperatures are not so high and there is mainly less precipitation than in summer. From mid-April, the amounts of rain increase considerably. This monsoon period lasts until September. During this time, Tainan may be hit by a hurricane or affected by hurricane activity in the region. There may then be days with sometimes more than 200-300 millimeters of precipitation within 24 hours. Temperatures in Tainan range from average maximums of 22-24 degrees in the winter to 32-34 degrees in the summer months. The high relative humidity can then cause high wind chill temperatures and thus muggy weather in Tainan.
