Where does the most rainfall occur in the world?
So which is the rainiest place in the world? Cherrapunji in the State of Meghalaya has for long been regarded the rainiest place in the world. Its annual mean rainfall based on the 30 years data (1931-60) is 1156.5 cm while that based on longer-term data (1851-1960) is 1131.4 cm. Later it was claimed that Waileale in the island of Kauai in Hawaii (USA) could be the rainiest place with an annual mean rainfall of 1168.4cm based on 32 years data (1931-62). Soon after it was noted that the annual mean rainfall at Mawsynram (Meghalaya) was 1187.3cm based on 39 years data (1941-1979). Of course, there are not long term data for either Waialeale or Mawsynram for a period comparable to those available for Cherrapunji. It appears that based on data of recent few decades, Mawsynram located only about 16 km west of Cherrapunji in the State of Meghalaya in India is the rainiest place in the world. Mawsynram also holds the record for highest rainfall in 24 hours in India which is 98.96 cm recorded
