Published by DOC/NOAA/NESDIS/NCDC > National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2015-08-17T00:00:00.000+00:00
The NOAA Climate Normals are a large suite of data products that provide users with many tools to understand typical climate conditions for thousands of locations across the United States, including the 30-year normals, 5, 10, 15, 20-year normals, agricultural normals, and others. For nearly 100 years, the 30-year NOAA Climate Normals have been a premier NOAA product of 30-year-averages of meteorological parameters. The 1981-2010 Climate Normals Product Suite has been expanded to meet more user needs and requirements spanning many different industries, including agriculture, heating and cooling, construction, and others. To ensure both quality and completeness, hundreds of NWS stations meeting stringent criteria are used, including those from NWS's Cooperative Observer Program (COOP) Network, some additional stations are included in the Supplemental Climate Normals for 1981-2010.
