Mawsynram, a village in the Indian state of Meghalaya, holds the record for highest average annual rainfall at approximately 11,872 mm (about 467 inches) per year, based on long-term meteorological records — narrowly surpassing its nearby rival Cherrapunji (also in Meghalaya), which holds several single-year and single-month rainfall records. Both owe their extreme rainfall to monsoon winds being forced sharply upward against the Khasi Hills.

Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
