Taipei Weather in May

Taipei weather in May continues to get warmer with the average temperature of 23 - 30 ℃ (73.4 - 86 ℉) and on somedays even soaring up to 33 °C (91.4 °F). With the arrival of the plum rain season, May is a very wet and humid month in Taipei. In some years, it rains almost every day for 3 weeks in a row. As a whole, Taipei May weather mostly remains rainy or cloudy.

The rising temperature of May foreshadows the coming summer, but the most intense heat has not yet to come. So May is still one of the best months for outings if it does not rain.
  Due to the quite warm Taipei temperature in May, tourists can pretty much pack some summer clothes, such as shorts, thin T-shirts, skirts, dress and sandals. At night, it's not as mild as it is during the day and you need to wear long sleeve top and long pants.

Besides, as the possibility of rain increases, you’d better bring appropriate rain gear like umbrella or raincoat. Also, it is suggested that you’re equipped with adequate waterproof clothing in case of the sudden downpour.
 
 With summer just around the corner, May is a great month to explore Taipei on foot and get a taste of early summer vibes. You could go to Yangmingshan Mountain to enjoy the calla lily flowers in full bloom, head to the vibrant Treasure Hill Arts Village after dark to appreciate the numerous free-to-enter art light exhibits. Taipei’s parks and biking trailsare quite popular on non-rainy days in May as people come out to enjoy the early summer sun.

May is suitable for some indoor activities as well, which means if the Taipei weather in May is rainy, you can tour some of Taipei’s many museums like National Palace Museum and Fine Arts Museum; explore the underground shopping zones at Taipei Main Station; plan a Taipei food tour in some theme restaurants or cafés...
