The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Drought report describes conditions in the United States, including Puerto Rico and the U.S. Affiliated Pacific Islands as warranted. A national drought overview is provided with detailed discussion on various regions. Several indices are presented: Palmer drought indices, Standard Precipitation Index, and other agricultural and hydrological indices. State, regional, and national moisture and precipitation status with historical rankings are available. Content of individual reports varies somewhat according to conditions and data availability. Reports were issued sporadically in 1999 and early 2000, with regular monthly reports beginning in September 2000. Annual reports are available from 2002.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview-National Wildfires provides a summary of wildland fires in the U.S. and related weather and climate conditions. Statistical summaries such as the number of fires and acres burned are provided as are reports from the U.S. Drought Monitor and fire danger maps. Monthly reports for the summer "fire season" and annual summaries begin in July 2002. Depending on conditions, reporting was extended beyond the summer and fall seasons, and beginning in 2009 a summary was generated for each month. Following the July 2013 report, and until further notice, NCEI will no longer issue the Wildfire component of its Monthly Climate report. All previous Wildfire reports will be maintained online. Updated statistics will be updated on our Wildfire Societal Impacts webpage.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Hurricanes & Tropical Storms report focuses primarily on storms and conditions that affect the U.S. and its territories, in Atlantic and Pacific basins. The report places each basin's tropical cyclone activity in a climate-scale context. Key statistics (dates, strengths, landfall, energy, etc.) for major cyclone activity in other basins is occasionally presented. Reports began in June 2002. The primary Atlantic hurricane season (June-November) is covered each year; other months are included as storm events warrant. An annual summary is available from 2002. These reports are not updated in real time.

The U.S. Monthly Climate Normals for 1981 to 2010 are 30-year averages of meteorological parameters for thousands of U.S. stations located across the 50 states, as well as U.S. territories, commonwealths, the Compact of Free Association nations, and one station in Canada. 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. As many NWS stations as possible are used, including those from the NWS Cooperative Observer Program (COOP) Network as well as some additional stations that have a Weather Bureau Army-Navy (WBAN) station identification number, including stations from the Climate Reference Network (CRN). The comprehensive U.S. Climate Normals dataset includes various derived products including daily air temperature normals (including maximum and minimum temperature normal, heating and cooling degree day normal, and others), precipitation normals (including snowfall and snow depth, percentiles, frequencies and other), and hourly normals (all normal derived from hourly data including temperature, dew point, heat index, wind chill, wind, cloudiness, heating and cooling degree hours, pressure normals). In addition to the standard set of normals, users also can find "agricultural normals", which are used in many industries, including but not limited to construction, architecture, pest control, etc. These supplemental "agricultural normals" include frost-freeze date probabilities, growing degree day normals, probabilities of reaching minimum temperature thresholds, and growing season length normals. Users can access the data either by product or by station. Included in the dataset is extensive documentation to describe station metadata, filename descriptions, and methodology of producing the data. All data utilized in the computation of the 1981-2010 Climate Normals were taken from the ISD Lite (a subset of derived Integrated Surface Data), the Global Historical Climatology Network-Daily dataset, and standardized monthly temperature data (COOP). These source datasets (including intermediate datasets used in the computation of products) are also archived at the NOAA NCDC.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - National Tornadoes provides a summary of tornadic activity in the United States. Tornado occurrences and significant events, including storms and outbreaks, are covered. Regular monthly and annual reports begin in July 2008. Spring "tornado seaso" reports are available for 2006 and 2008. In some months during climatologically inactive periods, the narrative part of this report may be omitted.
