We found each state’s annual average temperature, using data from the National Center for Environmental Information (NOAA).

For example, North Dakota experiences brisk, cold winters with an average January temperature of 6 degrees Farenheit. However, in summer temperatures 90° occur and are not uncommon. Yet temperatures for all days were averaged together evenly leading to an average temperature of 41.1°.
