Although it is reportedly the wettest place on Earth, with an average annual rainfall of 11,872 millimetres, this claim is disputed by Lloró, Colombia, which reported an average yearly rainfall of 12,717 millimetres between 1952 and 1989 and López de Micay, also in Colombia, which reported 12,892 mm per year between 1960 and 2012.
Primarily due to the high altitude, it seldom gets truly hot in Mawsynram. Average monthly temperatures range from around 11 °C in January to just above 20 °C in August. The village also experiences a brief but noticeably drier season from December until February, when monthly precipitation on average does not exceed. 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:
  1. 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.
  2. The alignment of the Khasi Hills places them directly in the path of the airflow from the Bay of Bengal, producing a significant uplift.
  3. 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.
