Rain

RECORDS

A low-pressure system that redeveloped off the New South Wales coast dumped a record 328 millimeters (13 inches) of rain in a day on Sydney, Australia in 1986.

The most rain ever recorded in one minute is 1.22 inches (31.2 millimeters), which fell in Unionville, Maryland, on July 4, 1956. During the thunderstorm, a combination of factors, including a warm and moist air mass, as well as a strong thunderstorm updraft, likely contributed to the intensity of the rainfall.  The record-breaking rainfall caused flooding and mudslides in Unionville. Several homes and businesses were damaged, and one person was killed.

In 1923 it rained on the Hebridean island of Islay for 89 days in a row — a British record.

With average annual rainfall as high as 12,000 mm (470 in) in some areas, Meghalaya, a state in Northeast India, is the wettest place on earth.

López de Micay in Colombia is the wettest town in the world, with an average of 315 rainy days a year (the least rainy month is February, with 23 rainy days), and an average of 16,000 mm (630 inches) of rainfall annually.

Surprisingly, the continent that receives the lowest amount of rain and snow is Antarctica.

The largest raindrops ever recorded, between 8.8 mm and 1 cm, were observed by scientists in the clouds above Brazil (1995) and the Marshall Islands (1999).


The wettest spot in the world is located on the island of Kauai in the Hawaiian Islands.. Mount Waialeale consistently records rainfall at the rate of nearly 500 inches per year.
