Record #00480Nature archive
At Mawsynram in Meghalaya, India, an available 26-year set of observations within 1941–1978 yielded mean annual precipitation of 11,873 mm, making it a leading candidate for the world's wettest place.

11873mm/year
Current record value
Mawsynram lies on the southern Khasi Hills, where the southwest monsoon's moist air is uplifted by the steep terrain and produces intense seasonal rainfall. A cooperative meteorological station collected daily readings near a local school.
The original paper compares Mawsynram, Cherrapunji and Hawaii's Mount Waialeale, while noting that unequal observing periods undermine precise direct comparisons among their averages.
Credible sources support core facts; the comparison scope or corroboration remains incomplete.
Basis: direct confirmation by an authority
The primary MAUSAM study reports 11,873 mm based on 26 available years in 1941–1978 and tentatively suggests the world's highest annual mean, while warning that direct comparison with Cherrapunji's 138-year series is inappropriate. Developing status is retained.
The observation periods and durations differ; the original study cautions against direct comparison.
