Mount Waialeale is a true funnel water on Earth. It’s actually a volcano with a caldera that receives amounts of rainfall that is completely disproportionate. According to records, there is an average fall about 11,500 millimeters of rain a year, although, there have been up to 17,300 mm in one year. Without doubt, its summit is one of the wettest spots on the planet.
The caldera of Mount Waialeale reaches up to 1,569 meters high above sea level. This is located on the island of Kaua in Hawaii. According to estimates, it may reach 360 days of rain a year, which is something that happens uniformly and without regard to seasons. The reason of heavy rainfall is related to its geographic location, exposure to frontal systems that bring rain to the island, and above all, the conical shape of the volcano, reaching a height that literally makes “discharge funnel clouds.”
The cliffs of the volcano causes the moisture-laden air to rise quickly to the clash with the volcano, dumping rain in one place and not gradually as it would in an area that is less abrupt. On the other side of the mountain, rainfall is only a few millimeters per year.
Obviously, getting to a place like this is no easy task. The heavy rains make the so very wet and the roads are almost not accessible. The easiest way to know this incredible sight is through a helicopter tour.
