Munnar is a monsoon-rhythm destination — the year splits into a lush green season and a dry golden one. The numbers below are real — monthly weather computed from the ERA5 climate archive for Munnar's exact coordinates — so this page answers the question most guides dodge: which months are actually worth your leave days?
