The U.S. Climate Normals Quick Access tool provides graphs and tables of average temperature, precipitation, and snowfall at more than 15,000 U.S. observation stations.
These maps show annual average temperature and precipitation for the Lower 48 U.S. states based on observations collected at thousands of U.S. weather stations from 1991–2021. (Normals are available for individual weather stations in Alaska and Hawaii .)
Map and data give the average annual precipitation for each American state, plus states are ranked from wettest to driest.
Information regarding the temperature, precipitation and sunshine for more than 5000 cities in the United States.
Search for maximum, minimum, and average temperature normals and precipitation total normals for individual station locations from about 15,000 stations across the United States. Find annual/seasonal, monthly, daily, or hourly conventional 30-year normals and 15-year normals normals by station names. Launch Quick Access
National trends for Mean Temperature, Maximum Temperature, Minimum Temperature, and Precipitation for each month and season can be accessed using the form below. Maps are available that depict trends for the most recent complete 30-year period and the complete period of record.
Average precipitation is the long-term average in depth (over space and time) of annual precipitation in the country. Precipitation is defined as any kind of water that falls from clouds as a liquid or a solid.
Normal annual U.S. precipitation as a percent of the 20th-century average for each U.S. Climate Normals period from 1901-1930 (upper left) to 1991-2020 (lower right). Places where the normal annual precipitation was 12.5 percent or more below the 20th-century average are darkest brown; places where normal annual precipitation was 12.5 percent ...
Areas shown in the lightest green received less than one inch of water from rain or snow. The darker the color on the map, the higher the precipitation for the month. Areas shown in dark blue received eight inches or more of precipitation that fell as either rain or snow.
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.
