Weather stations in South Dakota:


Automated Surface Observing System (ASOS) - The National Weather Service (NWS), Federal Aviation Administration (FAA) and Department of Defense operate this network of 967 stations located throughout the United States. The data generally available from ASOS stations includes hourly (and special) observations of air temperature, dew point, wind speed, wind direction, cloud cover, visibility, present weather, and precipitation. Via modem data can be obtained every minute (typically the most recent ~8 hours of observations are kept at the stations). For further information on the ASOS network visit the NWS ASOS home page or the FAA Automated Sensors home page.

We provide daily airport data, statewide and station-wise, since 01/01/2003, hourly data since 10/22/2003 and current-as-reported data (

19 Reporting stations: Aberdeen, Brookings, Buffalo, Chamberlain, Custer, Faith, Huron, Mitchell, Mobridge, Philip Pierre, Pine Ridge, Rapid City, Rapid City Airport, Sioux Falls, Sisseton, Watertown, Winner, Yankton


High Plains Regional Climate Center (HPRCC) Automated Weather Data Network (AWDN) - The HPRCC oversees and ingests data from various state agricultural networks and makes it available as the AWDN. The AWDN is comprised of 167 stations located primarily in High Plains region (11 in South Dakota). The network provides hourly observations of air temperature, relative humidity, solar radiation, soil temperature, wind speed, wind direction, and precipitation. For further information visit the HPRCC AWDN home page at: or the South Dakota AWDN home page.

We provide daily, statewide and station-wise, data and hourly automatic station data.

14 Reporting stations (South Dakota State University controlled): Aurora, Beresford, Brookings, Caputa, Cottonwood, Dakota Lakes, Dell Rapids, Gettysburg, Nisland, Oacoma, Oral, Pierre, Redfield, South Shore


NOAA/NWS Cooperative Observer Program - The National Oceanographic and Atmospheric Administration (NOAA) National Weather Service (NWS) oversees this network with 9765 participating cooperative observers located throughout the United States. This network provides daily observations (7am local time) of maximum and minimum air temperature, precipitation, snowfall, and snow depth. Some stations also provide soil temperature, evaporation, and wind run. These data are archived at NOAA/NCDC. For further information visit the NOAA/NWS Cooperative Observer Program home page at:

We provide historical coop station monthly data.

(Daily reporting stations: 181)

South Dakota Department of Transportation (DOT) Road Weather Information System (RWIS) Network - The South Dakota DOT operates this network throughout the state of South Dakota. The network provides hourly observations of air temperature, relative humidity, wind speed, and wind direction. For further information visit the South Dakota DOT RWIS home page or the Surface Systems, Inc Road Weather page.

Remote Automated Weather Station (RAWS) Network - The United States Forest Service oversees this network of stations owned and operated by state and local wildland fire agencies. The network typically provides hourly values of air temperature, dew point, relative humidity, wind speed, wind direction, precipitation, fuel temperature, and fuel moisture. The network consists of 726 stations located throughout the United States (5 in South Dakota), but heavily concentrated in the forested areas of the western mountains. These data are included within the University of Utah MesoWest and the NOAA/FSL MADIS data sets. For further information visit the USFS RAWS home page at:

Nationally, USGS surface-water data includes more than 850,000 station years of time-series data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall. The data are collected by automatic recorders and manual measurements at field installations across the Nation. Data are collected by field personnel or relayed through telephones or satellites to offices where it is stored and processed. The data relayed through the Geostationary Operational Environmental Satellite (GOES) system are processed automatically in near real time, and in many cases, real-time data are available online within minutes. Once a complete day of readings are received from a site, daily summary data are generated and stored in the data base. Recent provisional daily data are updated on the web once a day when the computation is completed. Annually, the USGS finalizes and publishes the daily data in a series of water-data reports. Daily streamflow data and peak data are updated annually following publication of the reports.

We provide a map of rivergauge precipitation daily.

KELO WeatherNet - KELO-TV in Sioux Falls, South Dakota operates this network of 14 stations with locations primarily in South Dakota (11 in South Dakota). The network provides up to 1-minute observations of air temperature, relative humidity, barometric pressure, wind speed, wind direction, wind gust, and precipitation. This network is included in the Iowa Environmental Mesonet (IEM). For further information visit the KELO weather page or the IEM SchoolNet page
