Lloro, Colombia, gets an average of 40 feet of rain a year. The people who live there make money by cutting down the trees in the nearby forest where you can count on its raining every day. Again, there is a discussion about this fact.
Cherrapunji, North-Eastern India was thought for many years to be the wettest place in the world. Here 10,820mm rain falls on average in a year, well short of the amount from Lloro. Unlike Colombia where the rain falls throughout the whole year, Cherrapunji gets most of its rain during the 'south-west monsoon', or wet season, between June and August. Cherrapunji does hold the record for the wettest month on record, recording 9,296mm in July 1861.
Actually, between 1860 and 1862 Cherrapunji was incredibly wet; between August 1st 1860 and July 31st 1861 (which overlaps parts of 2 wet seasons) 26,467mm rain fell. In the calendar year 1861 22,987mm rain fell, of which 22,454 fell between April and September.
