Which Indian State Receives The Highest Rainfall? List Of Top 5 States That Receive The Most Rainfall In India

India is a country with different climates that vary greatly, and seasons are primarily dependent on the amount of rainfall. Usually, the rainy season, called the southwest monsoon, starts at the beginning of June and goes on till September. More than 70% of the total yearly rainfall falls during this period. This season is crucial for agriculture, lakes, and the overall water supply. 

In 2025, the monsoon in Kerala arrived early, and it subsequently covered the entire country at a rapid pace. During May, there was more rain than ever before; therefore, by August, a lot of places were suffering drought. Some areas got 30 to 70% less rain than they usually get; as a result, the plants are stressed, and there is not enough water to drink. 

Have you heard that approximately 60% of the agricultural area in India is dependent on the monsoon rains? The Western Ghats and Northeast India are the regions most affected by the annual rainfall. 

In this article, we will take you through the top five Indian states that receive the highest rainfall and then discuss the reasons behind this high rainfall.

Which Indian State Receives The Highest Rainfall?

The Indian state with the most average annual rainfall is definitely Meghalaya, with the town of Mawsynram being the most notable. Mawsynram, which is located in the East Khasi Hills of Meghalaya, is considered the rainiest place on the planet, receiving more than 11,800 mm of rain each year. 

The area's peculiar topography, situated in the mountains and facing the Bay of Bengal, funnels moist winds directly into the region. Hence, there is heavy and repeated rain. Cherrapunji, another place in Meghalaya, used to be the rainiest spot but is now ranked only second after Mawsynram.
