Rainy Weather in US

United States' Rainiest Cities

Wettest Weather

Cities in the United States that receive the most precipitation each year don't necessarily have an exceptionally high number of rainy days.

Among the country's 51 largest urban populations, Buffalo, and Rochester New York most often have days when it's raining or snowing. Each city averages 167 wet days a year. But Buffalo ranks 26th in the total precipitation it receives annually, with 40.5 inches (1028 millimetres). Rochester gets even less rain and snow. At 34.3 inches (870 mm) of precipitation a year, Rochester ranks 37th among major US cities for highest annual precipitation.

New Orleans, on the other hand, where it usually rains over five feet a year, receives more precipitation than any big city in the USA. Yet it has far fewer wet days than many other cities. New Orleans ranks just 26th among large US cities in the number of days with precipitation, at 115 days a year.

The major cities included in the weather rankings represent the 51 metropolitan areas in the United States with the biggest populations, all those with over one million people in 2010, according to the US Census Bureau. A complete list of America's 51 largest urban centers is available here.
