Recent Precipitation and Temperature (including Normals and Anomalies) - Maps

U.S. Climate Data and Maps - Precipitation and Temperature

This site offers a huge assortment of maps and charts that put recent precipitation and temperatures in a climate context. Maps show how current conditions compare to Normal (long-term averages) for various time periods for the United States. Some data maps show data for the whole globe.

Where do these data come from?

Precipitation data are from CPC's Unified Precipitation Analysis (based on rain gauges and gridded sampling). Temperature data are from River Forecast Centers and Climate Assessment Data Base. 1981-2010 climatologies ("Normals") are used to calculate anomalies.

  • What can I do with these data?

    • Explore maps that show how recent precipitation and temperture compare to their long-term average values (also know as Normal).
    • For precipitation, explore maps of total precipitation, Normal precipitation, Anomaly (difference from Normal), and Percent of Normal.
    • For temperature, explore recent minimum and maximum temperatures, and how they differ from Normal minimum and maximum temps from 1981-2010.
