USA State Temperatures Mapped For Each Season

This sequence of USA maps illustrates how the temperatures change across the seasons.

The series allows you to visually compare average temperatures among American states and through the year.

A state's color is based on its average temperature for the season. Each color represents a different 5-degree Fahrenheit span of temperature. All the maps use the same color scale, ranging from dark blue for the coldest temperatures to dark red for the hottest.

The temperatures are state-wide averages calculated from data collected by weather stations throughout each state during the years 1971 to 2000 and made available by the NOAA National Climatic Data Center of the United States.

You can see the numbers behind each map plus more information about state-wide temperature averages on a page for each season: Spring, Summer, Fall and Winter.
