December weather forecast
Taiwan

December in Taiwan marks the peak of the winter season. In northern regions, including Taipei, temperatures generally range from 15°C (59°F) to 20°C (68°F). The influence of the northeast monsoon brings steady rain to these parts, resulting in an increase in average monthly precipitation to 90mm (3.54"). Despite the cooler temperatures and rain, there can still be periods of sunshine during the day, giving a pleasant contrast.

In the central and southern parts of Taiwan, temperatures typically fluctuate between 18°C (64.4°F) and 25°C (77°F). Cities such as Kaohsiung and Tainan continue to be warmer, often experiencing temperatures reaching the upper limit of this range. These regions, shielded from the northeast monsoon, remain largely dry and sunny throughout December, making them a popular winter escape.

Compared to November, December experiences further drops in temperature, and the north sees an increase in rainfall due to the full impact of the northeast monsoon season. As the island transitions into the new year and the subsequent month, January, Taiwan continues to experience cooler temperatures and steady rain in the north, while the central and southern regions enjoy mostly sunny and mild winter weather.
