NOAA: U.S. warmer and drier than normal in June

July 8, 2011

June 2011 brought temperature and precipitation extremes across the United States. An oppressive heat wave, accompanied by intensifying drought conditions, shattered temperature records in the South and Southwest. Overall, the nation had its 19th driest and 26th warmest June on record, according to scientists at NOAA’s National Climatic Data Center (NCDC) in Asheville, N.C.

The average U.S. temperature in June was 70.7 degrees F, which is 1.4 degrees F above the long-term (1901-2000) average. Precipitation, averaged across the nation, was 2.48 inches. This was 0.41 inch below the long-term average, with large variability in different locations. This monthly analysis, based on records dating back to 1895, is part of the suite of climate services NOAA provides.

NCDC’s monthly reports 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 new scientific methods improve NCDC’s processing algorithms.
