NOAA: U.S. had above normal temperatures and precipitation in March

April 8, 2011

Last month, temperatures and precipitation in the contiguous United States averaged above normal, according to scientists at NOAA’s National Climatic Data Center in Asheville, N.C. The average temperature in March was 44.0 degrees F, which is 1.4 degrees F above the long-term (1901-2000) average. March precipitation, while record dry in areas like Texas, was overall 0.22 inch above the long-term average. The January – March temperatures were near-normal, while average precipitation was below-normal.

This monthly analysis, based on records dating back to 1895, is part of the suite of climate services NOAA provides.

NCDC’s State of the Climate reports, which assess the current state of the climate, are released soon after the end of each month. These analyses are based on preliminary data, which are subject to revision. Additional quality control is applied to the data when late reports are received several weeks after the end of the month and as increased scientific methods improve NCDC’s processing algorithms.

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Visit us on Facebook.
