Methodology
We found each state’s annual average temperature, using data from the National Center for Environmental Information (NOAA).
To determine each state’s average temperature, all 12 months were averaged together. This means that some states may experience a greater spread of temperatures throughout the year.
For example, Hawaii experiences temperate, fairly even, weather all year long. However, Southeastern states experience mildly chilly winters with summer temperatures reaching over 100° unpleasantly. Yet when all 12 months are averaged together, the Hawaii and Louisiana’s average temperatures are not too far apart– even though one has far hotter days.
