About 71% of the Earth’s surface is covered in water, making it an especially wet planet. In addition to the oceans, rivers, and lakes, water exists in the air in the form of water vapor. Because of the water cycle, this vapor at times condenses and returns to the Earth’s surface as rain.

While rain is common across most of the globe, certain places receive far more rainfall than average. This poses serious problems in some areas, as excess rain can lead to flooding, landslides, and other issues. It can be especially damaging to areas at low elevation already at risk from rising sea level. Here are the cities that will soon be underwater.

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 U.S. 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.
