Local Climatological Data (LCD)

Local Climatological Data (LCD) consist of hourly, daily, and monthly summaries for approximately 1,600 U.S. locations.

  • Local Climatological Data (LCD)
    Data are available based on when the station began until present. Please note, there may be a 48-hour lag in the availability of the most recent data.
  • LCD Sample
    The LCD product consists of four forms. Each of these forms is also available in comma separated values (CSV) format. Follow these links to view LCD sample before accessing the data.
  • QCLCD ASCII Files
    QCLCD ASCII, or plain text, data files provide monthly summaries of observations for all stations. Files between 2005 and 2007 may not match the same information presented in the QCLCD web form, and the Hourly Wind Speed is represented in knots (kts) rather than miles per hour (mph) for this period. The QCLCD ASCII data are available as compressed zip files. To download them, right click on the filename and select Save As. Then decompress the files using WinZip (Microsoft Windows/NT environment) or standard UNIX gunzip/tar.
