On the face of the earth, if there are places which are suffering from lack of rains and drought-like conditions, there are places which are dealing with floods and more recurrent floods. Though rains are highly beneficial for a number of things and are very basic for the survival of life on the earth, an excess of it is actually bad. If we say that rains are good for our crops, excessive rainfall can surely de-capacitate the crops and can be a reason for more serious problems.

It is perfect for beach activities such as sunbathing and surfing but as the monsoon season starts in May, it is recommended that no such activities take place as it could be fatal.

Also tropical storms are very common in Costa Rica which cause floods, shortage of water to drink, trees falling and landslides. People are stranded and thousands of them land up in shelters.

5. Panama 

At number 5, we have Panama which receives the same amount of rainfall as Costa Rica but it rains there for almost 9 months of the year starting from April till December. The location of this country is such that it receives the most rainfall due to process of vaporization. Plus the places located near the sea shores have the maximum share of the rainfall.

3. Papua New Guinea 

number 3 on the list of top 10 countries with highest rainfall is Papua New Guinea. The rainfall that this country receives in a year is approximately 3,142 mm.

Countries with the Highest Rainfall in the world

at number 1, we have the rainiest place in the world – Colombia. Rainfall is a permanent feature there barring months of July and August where less rainfall is recorded and tourists are also allowed to visit Colombia. The infrastructure, as well as the living beings, get extremely disturbed there due to high rainfall and it is still the same. Due to heavy rains, landslides happen leaving many dead. Due to floods, many buildings get destroyed. The average precipitation in Columbia is 3240 mm per year which is the highest in the world. Most of the time, this place is under floods. The Pacific coastline suffers from the most disastrous rainfall and it is on a daily basis. And due to the presence of rainforests, the condensation cycle works. Besides, it showers in Colombia almost every day.


As far as the environment is concerned, rains are required for living. But an excess of it could be fatal. The countries mentioned above are located in close proximity of mountainous region or closer to large water bodies, and eventually clouds get created due to the moisture of this place. On the whole, if all through the year the weather remains constant, more and more rainfall in these regions could be expected. And places with tropical climate have the same weather all 365 days a year which is why it rains the most in these places. Landslides and floods are two repercussions of the heavy rainfall and they create havoc in the lives of people.
