U.S. Annual Climatological Summaries

Annual Summaries

browse graphicStation locations for Annual Climatological Summary data.
Annual Climatological Summary contains historical monthly and annual summaries for over 8000 U.S. locations. Observing stations are located in the United States of America, U.S. Virgin Islands, Puerto Rico, and Pacific islands of the U.S. and associated nations. The major parameters are: monthly mean maximum, mean minimum and mean temperatures; monthly total precipitation and snowfall; departure from normal of the mean temperature and total precipitation; monthly heating and cooling degree days; number of days that temperatures and precipitation are above or below certain thresholds; and extreme daily temperature and precipitation amounts. Annual Climatological Summary is derived from the NCDC Summary of the Month dataset (DSI-3220).

Purpose The Annual Climatological Summaries of U.S. station data (from COOP and ASOS stations) was developed to meet the needs of climate analysis studies that require data at monthly and annual time resolutions. It includes temperature average max, min, and extremes, departures from normal, degree day, and frost/freeze values plus precipitation averages and extremes including snowfall data. Data are typically delayed 6 months or more.
