Where the water is, month by month

There is no bad month for waterfalls — only the wrong waterfall for the month. The monsoon puts India's Western Ghats in flood from June; the southern summer fills Victoria Falls by April; snowmelt turns Norway and Yosemite on in late spring; and in the depths of winter the northern falls freeze into climbing routes.

Each month page lists every waterfall in our index at its best that month, grouped by continent, with the full guides that cover what's open and what's closed. For the bigger picture, read the four things that decide a waterfall trip.
