Paris is a four-season destination where each visit is a different city. The numbers below are real — monthly weather computed from the ERA5 climate archive for Paris'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 April, July, November, skip January if you can, and read the packing notes before you book. Autumn color or spring bloom weeks are short — time them and the trip upgrades itself.
