NOAA: March Temperature Near Average for the U.S.

April 10, 2009

The March 2009 temperature for the contiguous United States was near the long-term average, based on records going back to 1895, according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C. Heavy precipitation last month also pushed the Red River, along the Minnesota-North Dakota border, to record levels, triggering major floods.

The average March temperature of 43.2 degrees F was 0.6 degrees F above the 20th century average. Precipitation across the contiguous United States in March averaged 2.51 inches, which is 0.11 inch above the 1901-2000 average.

NCDC’s preliminary 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 understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.
