U.S. Climate at a Glance


These data are primarily intended for the study of climate variability and change. Whenever possible, observations have been adjusted to account for the artificial effects introduced into the climate record by factors such as instrument changes, station relocations, observer practice changes and urbanization. As a result, some values available on this site differ from the official observations.

For official station observations, please contact the NCDC Climate Services and Monitoring Division at ncdc.orders@noaa.gov.
