The official normals are calculated for a uniform 30 year period, and consist of annual/seasonal, monthly, daily, and hourly averages and statistics of temperature, precipitation, and other climatological variables from almost 15,000 U.S. weather stations.

The color in each climate division shows the average of the highest temperature recorded every day of the month for the 30 years from 1981 to 2010. Shades of blue show where the highest daily temperatures measured across a climate division from 1981 to 2010 averaged below 50°F for the month. The darker the shade of blue, the lower the temperature.

Member states of the World Meteorological Organization(link is external)(WMO) are required to calculate their country’s normals at ten-year intervals. Countries follow recommendations by the WMO, which provides a framework for international cooperation among meteorologists, climatologists, and hydrologists. The decadal update is the equivalent of the Census for those who use the dataThe decadal update is the equivalent of the Census for those who use the data. It replaces the previous set of U.S. Normals, which cover all 50 states and U.S. territories such as Puerto Rico and Guam. NCEI and its predecessors have been the official source for U.S. Climate Normals since the 1950s. New data come from approximately 8,700 National Weather Servicestations operated by NOAA, which include Automated System Observing Stations(ASOS) and Cooperative Observer Program(COOP) stations. For the first time, Precipitation Normals have been created for more than 770 Snow Telemetry (SNOTEL) stations manag...
changes can be subtle, depending on the region, season, and timeframeAs anticipated, changes have occurred in averages since the last ten-year update. Since two-thirds of the data (1991–2010) in the new set overlap with the previous version, changes can be subtle, depending on the region, season, and timeframe. Nonetheless, an upward shift in temperature averages is evident. The 1981–2010 average temperature for the contiguous U.S. was 52.8°F while the new average temperature for the contiguous U.S. for 1991-2020 is 53.3°F. The new normals period, 1991-2020, is the warmest on record for the country. But warming is not ubiquitous across the contiguous U.S. in either geographic space or time of year.Changes vary from season-to-season and month-to-month. For instance, the north-central U.S. Temperature Normals—for those in the Northern Plains and Upper Midwest—have cooled from 1981–2010 to 1991–2020, especially in the spring. The South and Southwest are considerably warmer. Normals wer...
U.S. Normals are useful to understand present-day conditionsRather than track or define long-term trends or changes in climate, U.S. Normals are useful to understand present-day conditions. For climate monitoring activities at NCEI, longer periods are referenced. The monthly State of the Climate reportsproduced for the United States and globe use twentieth-century averages (1901–2000) as benchmarks and will continue to do so. The yearly Bulletin of the American Meteorological Society State of the Climatereport also relies on longer periods of record. Several reasons underlie the use of the twentieth-century averages for climate change monitoring: 1. The 1901–2000 baseline offers more consistency as conditions change over time and is not subject to updates every 10 years. 2. The period is an easy-to-understand range when discussing long-term climate change with non-technical audiences. However, long-term trends from decade to decade can affect baseline “normal” weather conditions. Fo...
Additional products and services will be released later in 2021 and into 2022, including Daily Gridded Temperature and Precipitation Normals. Plans are also underway for NOAA NCEI to become a repository for climate normals from countries around the world.
