Earth is an ocean planet. Water in liquid or frozen form covers 75% of Earth’s surface and fills the sky with clouds. Atmospheric rivers known as jet streams meander and encircle the Earth, contributing to seasonal patterns of rainfall in places across the globe. In many parts of the United States, there is the familiar association of rain with springtime. In other parts of the world, there is always rain.
To identify the rainiest places on Earth, 24/7 Wall St. reviewed average annual rainfall recorded by weather stations around the world and compiled by the Global Historical Climatology Network, a program of the National Centers for Environmental Information (NCEI).
We calculated the average annual rainfall from precipitation in the years 1997 through 2018. Weather stations that did not have at least five years of data available between 1997 and 2018 were not considered.
The most frequently occurring rainiest places on Earth are those in Malaysia and in other South Asian regions. Four places in the United States made our list.
