The 10 Wettest Places on Earth
The ten wettest places on earth that are occupied or regularly visited by humans, based upon average annual rainfall
These are the ten wettest places on earth ranked by their average annual rainfall. Each one of the top five wettest places on Earth averages over 400 inches of rain per year. That is better than one inch of rain per day, on average. Most of these places boast about how much it rains there, and some tourists do visit the areas, especially to see the waterfalls in the areas.
The 10 Wettest Places on Earth
1. Lloro, Colombia - 523.6" of rainfall per year
The city of Lloro in the western part of Colombia in South America receives an annual average rainfall of 523.6" of rain per year. That makes Lloro, Colombia the wettest place on earth.
2. Mawsynram, India- 467.4"
The village of Mawsynram in eastern India is the second wettest place on earth with an average annual rainfall of 467.4". Mawsynram receives plentiful rainfall every year from weather systems moving up the Bay of Bengal in the Indian Ocean, especially during the monsoon season.
3. Mount Waialeale, Kauai- 460"
Mount Waialeale is a 5,148 foot mountain located in the center of the island of Kauai in Hawaii that receives an average annual rainfall of 460" per year. The abundant rain that falls on top of Mount Waialeale falls off of the mountain in a long series of waterfalls collectively known as the Weeping Wall. The Weeping Wall waterfalls (first photos above) is a very popular tourist attraction on Kauai, and in Hawaii. Unless you are an intrepid hiker, you have to take a helicopter ride to see the Weeping Wall.
Mount Waialeale is an old shield volcano with very steep sides. As weather systems roll through the area they go up the sides of Mount Waialeale and get stuck and end up dumping all their moisture right on top of the mountain. The name of the mountain means overflowing water in the Hawaiian language.
In more recent times, the place known as Big Bog on Maui has averaged higher rainfall levels than Mount Waialeale. But that data only goes back 25 years or so. The data for Mount Waialeale dates back to 1912.
4. Cherrapunji, India - 425"
The town of Cherrapunji, also spelled Cherrapungee, in eastern India receives 425" of rainfall annually, which makes it the fourth wettest place on earth. Cherrapunji is located only about 10 miles southeast of Mawsynram, and also receives its abundant rainfall from weather systems that move up, and pick up moisture from the Bay of Bengal.
5. Debundscha, Cameroon - 405"
The village of Debundscha in southwest Cameroon in Africa receives 405" of annual rain, making it the fifth wettest place on earth. Located at the base of 13,255 foot high Mount Cameroon, Debundscha lies just inland from the Atlantic Ocean at the Bight of Bonny.
The village, no doubt, receives its abundant moisture right off the Atlantic Ocean, with Mount Cameroon blocking storm systems from moving inland. As the storm systems get stuck on Mount Cameroon, they drop their moisture on Debundscha.
6. Quibdo, Colombia - 354"
Located only some 15 miles from Lloro, both rainy cities in Colombia receive all the rainfall because they are located east of the Andes Mountains. The Andes Mountains block weather systems so they dump all their moisture where they get stalled.
7. Bellenden Ker, Queensland, Australia - 340"
Bellenden Ker is actually a mountain that is 5,225 feet high located in Queensland, Australia. The summit of the mountain receives the highest annual recorded rainfall in all of Australia.
8. Andagoya, Colombia - 281"
9. Henderson Lake, British Columbia, Canada - 265"
The wettest place on the North American continent, Henderson Lake is located on Vancouver Island in the northeastern Pacific Ocean just off the British Columbia mainland.
10. Crkvice - 183"
Crkvice receives the highest annual rainfall of any inhabited place in all of Europe.
