Taiwan is very enjoyable any time of the year, though the best time to visit Taiwan is from mid- September until November, when the skies are sunny, the humidity is low, temperatures are cool, and there is little rainfall compared to the rest of the year. December to March coastal regions are cool with heavy cloud cover and frequent drizzle. Temperatures start rising in April, and by May days are hot, sticky, and at times uncomfortable; rains May - August are typically short, heavy afternoon thunderstorms surrounded by sun.
