Taipei is a warm-all-year destination where rainfall, not temperature, decides your best window. The numbers below are real — monthly weather computed from the ERA5 climate archive for Taipei's exact coordinates — so this page answers the question most guides dodge: which months are actually worth your leave days?
The short answer: aim for January, February, December, skip October if you can, and read the packing notes before you book. The dry season's first and last weeks offer peak weather at below-peak prices.
