Travelling in January
January is one of the driest and coolest months in Taiwan, but even so average temperatures only drop to 16°C in Taipei, which can also be cloudy. Keelung and the northeast coast, however, is subject to monsoon weather at this time of year, making the surfing wetter than usual, and it is cooler at altitude in the central highlands. Kenting National Park and Taiwan’s southern regions, meanwhile, are warm and sunny, lending the perfect opportunity for a winter beach break with average temperatures nudging 25°C.
Travelling in February
February is one of Taiwan’s cool winter months, although average temperatures are still around 16°C in Taipei. It is colder at altitude in the central mountains, but Kenting and the tropical south are much warmer and sunnier, with temperatures averaging 25°C. Rainfall is relatively low, although there is more chance of a shower in February than there was in January. The exception is Taiwan’s north east coast which can be cloudy and thundery during February due to the north east monsoon.
Travelling in March
March marks the start of spring in Taiwan and brings a welcome increase in average monthly temperatures, but this is mirrored by a similar increase in showery rainfall. In Taipei, you can expect temperatures in the region of 18°C and showers, but in Keelung on the north east coast it is still unseasonal, due to the north east monsoon clouds and squalls. March is a good time for hiking in the central highlands, whilst southern Taiwan is still enjoying ideal beach weather, with the temperatures in the southernmost regions around 25°C.
Travelling in April
April is one of the best months of the year to visit Taiwan, before the heat and humidity of the summer season. This is the most popular time to go hiking in the spectacular high mountain ranges, exploring Mount Sylvia and Xueba National Park. Average temperatures are a delightful 22°C in Taipei, and at this time of year the north is drier than the tropical south. The north east monsoon is over, opening up the possibility for coastal exploration and watersports on the north east coast beyond Keelung City.
Travelling in May
It’s getting steadily hotter and wetter in Taiwan by the time May arrives. Average temperatures of 24°C are typical in downtown Taipei, with the possibility of afternoon downpours. The rainy season may be on its way, but May is still considered a good month to visit the lush, towering peaks and National Parks of the interior. Temperatures are beginning to even out between the north and south, but in southern regions of Taiwan you can already expect high temperatures that reach over 30°C. It may be inviting beach weather in Kenting but bear in mind that the south is now much wetter than the north, and afternoon storms are common.
Travelling in June
Summer in Taiwan means heat and rain, and June brings both. June is the wettest month of the year throughout Taiwan. With average temperatures in Taipei up to 27°C, it’s perfect weather for coastal activities in the north, to make the most of a sea breeze. In the tropical south it’s hotter still, peaking above 30°C, but it’s also wetter than in the north now that the south west monsoon is kicking in. This weather system will bring major rainfall to the highlands, so June is not the best time for trekking.
Travelling in July
July is Taiwan’s hottest month and also one of its wettest. In Taipei, temperatures soar to a steamy average of 30°C making travelling and sightseeing less enjoyable. We’re now deep into typhoon season which is good news for surfers heading to Jin Shan and Baishawan in the far north of the island. Down in the tropical south the south west monsoon continues to bring heavy downpours, but the beaches still beckon as temperatures are peaking around 32°C.
Travelling in August
August is a peak summer month in Taiwan, with average temperatures in Taipei hitting 29°C and slightly hotter temperatures in the tropical southern regions of the country. Typhoon season continues, with thunderstorms expected most afternoons, especially in the south. But there is still plenty of sunshine to be enjoyed between the storms. Over on the east coast, the weather is more bearable, making August a good time to visit Yilan and Hualien County.
Travelling in September
September sees summer draw to an end in Taiwan and brings about a slight dip in average temperatures to 24-30°C and less heavy downpours, although rainfall should still be expected.
Travelling in October
October is a popular time of year to visit Taiwan, avoiding the summer’s high temperatures and heavy rainfall which is now abating. Taipei’s average monthly temperature is down to a much more pleasant 24°C and the rain starts to clear in the hotter, sunnier south, which is now experiencing averages of around 26°C. However, October sees the arrival of the north east monsoon, bringing cloud and occasional storms to Keelung and the north east coast.
Travelling in November
November can be a rewarding time to visit Taiwan. Taipei’s average monthly temperature is still a very pleasant 21°C, and although the north east monsoon is prone to bring cloud and the chance of thunderstorms to Keelung and the north east coast, the rest of the country is relatively bright and sunny – with spectacular autumn colours a draw, especially in the mountains and Yangmingshan National Park. In the tropical south, it’s still beach weather, with average temperatures around 25°C.
Travelling in December
Although the north east coast is stormy and cloudy in December due to the effects of the monsoon, the rest of the country is enjoying favourable weather conditions, making December a good time of year to visit Taiwan. Snowfall will be due in the mountains, making for spectacular scenery and skiing is a possibility in Yashun this month. In the tropical south it’s still very much beach weather, especially in the furthest reaches such as Kenting.
