NOAA: November Warmer than Average in U.S., January-November Temperature Near Average for U.S.

December 11, 2008

The November 2008 temperature for the contiguous United States was warmer than the long-term average, according to NOAA’s National Climatic Data Center in Asheville, N.C. The January-November 2008 temperature was near average.

The average November temperature of 44.5 degrees F was 2.0 degrees F above the 20th Century average. Precipitation across the contiguous United States in November averaged 1.93 inches, which is 0.20 inch below the 1901-2000 average.

For the January-November period, the average temperature of 54.9 degrees F was 0.3 degree above the 20th Century average. The nation’s January-November temperature has increased at a rate of 0.12 degrees per decade since 1895, and at a faster rate of 0.41 degrees each decade during the last 50 years. All findings are based on a preliminary analysis of data based on records dating back to 1895.

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.
