Mawsynram is located at 25° 18′ N, 91° 35′ E, at an altitude of about 1,400 meters (4,600 ft), 15 km west of Cherrapunji, in the Khasi Hills in the state of Meghalaya (India).
Climate and rainfall
Under the Köppen climate classification, Mawsynram features a subtropical highland climate (Cwb) with an extraordinarily showery, rainy and long monsoonal season and a short dry season. Based on the data of a recent few decades, it appears to be the wettest place in the world, or the place with the highest average annual rainfall.[6] Mawsynram receives over 10,000 millimetres or 390 inches of rain in an average year, and the vast majority of the rain it gets falls during the monsoon months. A comparison of rainfalls for Cherrapunji and Mawsynram for some years is given in Table 1.[7] Mawsynram receives the highest rainfall in India. Although it is reportedly the wettest place on Earth, with an average annual rainfall of 11,872 millimetres (467.4 in), this claim is disputed by Lloró, Colombia, which reported an average yearly rainfall of 12,717 millimetres (500.7 in) between 1952 and 1989 and López de Micay, also in Colombia, which reported 12,892 millimetres (507.6 in) per year between 1960 and 2012. According to the records observed by the Indian Meteorological Department, it was seen that while its neighbour, Cherrapunji is having a significant decreasing trend in rainfall, Mawsynram on the other hand is experiencing a slight increase in its rainfall pattern which put its average annual rainfall from 1950 to 2000 at 12,393 millimetres (487.9 in) and from 2000 to 2020 at 12,120 millimetres (477.2 in). The precipitation table below shows the average monthly record from 1950 to 2000.

Primarily due to the high altitude, it seldom gets truly hot in Mawsynram. Average monthly temperatures range from around 11 °C (51.8 °F) in January to just above 20 °C (68 °F) in August. The village also experiences a brief but noticeably drier season from December until February, when monthly precipitation on average does not exceed 30 millimetres (1.2 in). The little precipitation during the village's "low sun" season is something that is shared by many areas with this type of climate.

Three reasons can be cited for high rainfall at Mawsynram:
- The warm moist winds of the northward-moving air from the Bay of Bengal during the monsoon, which cover an extensive area but are forced to converge into the narrower zone over the Khasi Hills, thus concentrating their moisture.
- The alignment of the Khasi Hills (east to west) places them directly in the path of the airflow from the Bay of Bengal, producing a significant uplift (plus cooling, further condensation and thus more rain).
- Finally, uplift over the Khasi Hills is virtually continuous in the monsoon period because the lifted air is constantly being pulled up by vigorous winds in the upper atmosphere; hence, the rainfall is more or less continuous.
Natural landmarks
Located in Mawsynram, is a cave named Mawjymbuin, known for its stalagmites.[19] Inside this cave is a pair of notable speleothems - stalactites shaped like a cow's udder over a large stalagmite. The area is known for its many caves, both commercialized and non-commercialized.
