Taichung Weather

Taichung has a warm humid subtropical climate bordering on a tropical monsoon climate, with an average annual temperature of 23.3 °C (73.9 °F). The highest temperature of the year occurs in July and August, while the lowest temperature occurs in January and February. Daytime temperatures remain warm to hot year-round, though night time temperatures during the winter months are significantly cooler than those during the summer and the warm daytime temperature. Its average annual rainfall is just above 1,700 mm (67 in), relatively low compared to other major cities of Taiwan. The average humidity is 80%.

Due to the protection provided by the Central Mountain Range to the east and the Miaoli hills to the north, Taichung is rarely severely affected by typhoons. However, occasional typhoons emerging from the South China Sea can pose a threat to the city as evidenced by Typhoon Wayne in 1986, which struck the west coast of Taiwan near Taichung.

Due to Taichung plain’s strong radiative cooling effect, Taichung City is one of the few cities of Taiwan where the year round average daily low temperature falls below 20 °C (68 °F), with even most cities of northern Taiwan, such as Taipei and Keelung having an average low of over 20.5 °C (68.9 °F).
