A ranking of the countries that receive the highest and lowest average annual precipitation in millimeters, per latest data from the World Bank.
Many of the wettest nations are located near the equator, in proximity to the Intertropical Convergence Zone (where trade winds from both hemispheres meet). These countries also have significant coastlines that lead to higher than average rainfall.
