Where and when was the highest rainfall ever recorded?

Puerto Lopez de Micay, a small town near the coastline of western Colombia, may be a new contender for the wettest inhabited place in the world.

Between April 1960 and February 2012, an average annual rainfall of just over 507 inches has been recorded at the weather observation station here, including an astonishing 937 inches of rain in 1984. (Its driest year, 1980, brought "just" 243.9 inches - roughly 4 times what the wettest cities in the U.S. receive.)

Precipitation in Puerto Lopez de Micay is also amazingly consistent. Some years (like 1984 and 1985) have seen measurable rainfall on all but about 10 to 15 days throughout the year.
