Taiwan Weather & Climate: Monthly Averages

Taiwan has both tropical and humid subtropical climate zones, with its highest mountain peaks exhibiting tundra-like conditions.

Climate Patterns in Taiwan

Because of this, the middle mountain range dominates the center of the island and greatly influences the distribution of different weather conditions. Consequently, western Taiwan is partially guarded from the influence of the monsoon, making this area drier; simultaneously, the northern and eastern parts have more cloud cover and are wetter due to the same monsoon influence.

There are two prevailing types of monsoons in Taiwan: the northeast and southwest. The northeast monsoon, or winter monsoon, blows from late October through March. During this period, the climate is cooler, and rainfall is regular, especially in the northern and eastern parts of the island.

The southwest monsoon is active from June to September, bringing warmer and wetter conditions, particularly in southern and central Taiwan. This period is also marked by heightened humidity and occasional intense downpours, categorizing it as the most humid and rain-drenched segment of the year.

Rainfall and Temperature

Rainfall is abundant throughout Taiwan. For instance, the capital, Taipei, receives over 2000 mm (79 in) of rainfall annually, with the majority occurring during the summer. Visitors to the city soon learn how often it rains and that a spare umbrella can be rather handy. In fact, many high-end hotels provide free umbrellas to their guests. Even the driest parts of Taiwan receive a significant amount of rain, averaging around 900 mm (35 in) annually, while the wettest areas receive as much as 5000 mm (197 in) per year.

The climate of the southern part of Taiwan is basically tropical, with warm temperatures. Usually, temperatures range from 25°C (77°F) to 34°C (93°F). In winter, from December to February, temperatures are slightly lower and usually range from 18°C (64°F) to 24°C (75°F). Still, the weather remains pretty mild.

Typhoons in Taiwan

Taiwan is susceptible to hurricanes, particularly from June through October. These tropical cyclones, which the locals refer to as "typhoons," can bring heavy rainfall and strong winds. Sometimes, they may cause serious flooding. Due to its location bordering the Pacific Ocean, the east coast of Taiwan is very prone to direct impacts from typhoons. Tourists planning to visit during this period should stay updated with weather news.
