American summers are hot. While this spring was unusually cold, there is a strong likelihood that temperatures this summer will be unusually high across most of the country, particularly the western and northeastern United States — according to federal scientific agency predictions based on 139 years of temperature records.
Temperatures vary widely throughout the year across North America, and over the course of history. The coldest temperature ever recorded in the continent was -84.4° Fahrenheit in Snag, a small village in Canada’s Yukon Territory. At the other end of the spectrum, temperatures reached a staggering 134° Fahrenheit in Furnace Creek, Death Valley, California on July 10, 1913.
Temperatures can also vary substantially within regions and within states. Cities, in particular, due in part to the presence of heat-trapping materials such as asphalt, metal, and concrete are often a state’s hottest areas. Based on the most recent historical temperature data from the National Oceanic and Atmospheric Administration (NOAA), 24/7 Wall St. identified each state’s hottest city.
In 67 of the nearly 200 medium to large cities, daily 90 ° Fahrenheit or higher temperatures are completely normal during the hottest month of the year. In 20 cities across Arizona, California, Nevada, and Texas, 100 or more days of 90° Fahrenheit plus weather are recorded on average annually.
