Believe it or not, a really strong wind can reverse the flow of a waterfall. You can experience this phenomenon at these places.
Waterfalls are large volumes of water that drops vertically over a steep surface. If that flow encounters tenacious wind, it can push the voluminous deluge back creating a mostly ephemeral, yet astounding phenomenon called upside-down, inverted or reverse waterfalls. Though, no one can predict the occurrence of reverse waterfalls with surety because it depends on a stringent set of conditions. There are some places in the world where the probability of such occurrences can be expected.
Since these inverted waterfalls can generally be approached by walking or hiking, gear yourself up with appropriate footwear and be well prepared to get wet especially if the viewpoint is on a hill ledge with the wind blowing your way - where an umbrella or a raincoat can come handy.
Some places where the chance of experiencing a reverse waterfall can be amplified are:
Kinder Downfall (on Kinder River), Central England
Locally famous, the 80-foot Kinder Downfall, near Hayfield, in the Peak District on the edge of Kinder Scout reduces to a trickle during the summer. If a particularly strong wind is incidental, the water channel gets whisked up in a misty vapour.
Cliffs of Mohair, Western Coast, Ireland
Running for about 8 miles, at the southwestern edge of the Burren region, close to Liscannor village in County Clare, the waterfall is susceptible to a fiesty upwardly blowing wind.
Waipuhia Falls, O'ahu, Hawaii
Though it is said that this downflow on the right-hand side of Pali Highway, at
Kāneʻohe, in the city of Honolulu, seldom defeats the gusting north-easterly trade winds blowing off the Mount Konahuanui, to kiss the ground, a full upside downflow is considered to be a rare phenomenon but not impossible.
Furepe Falls, The Shiretoko National Park, Hokkaido, Japan
Reachable by boat, Furepe Falls is surrounded by scenic Shiretoko National Park which covers most of the Shiretoko Peninsula at the northeastern tip of the island of Hokkaidō. The waterfall drops down a sheer cliff into the Sea of Okhotsk, is occasionally known to oblige with the sightings.
Cachoeira da Fumaça (Smoke Waterfall), Chapada Diamantina National Park, Brazil
A sheer drop of 1,100 feet down the craggy rocks, disperses the water into smoke and when it catches the upwind, it transforms into plumes of sprays.
Talca, Maule Region, Central Chile
Spectacular in itself, on a windy day it seems as if a pair of hands is scooping up the water.
Rjúkandi Waterfall, Jökuldalur valley, Iceland
Situated amidst Iceland's windiest regions in Eyjafjöll mountain range, water doesn't have much chance of a continuous straight fall.
