Which metros suffer through the summer, and where do residents just chill out?
We just released our new Sperling Heat Index, and I’m pretty excited about it. It not only uses the average summer high temperature, but also includes the nighttime low temperature and dew point (a measure of humidity).
Of the 50 largest metro areas in the United States, Phoenix, Las Vegas, and Houston have the hottest summers, and Seattle, San Francisco, and Portland have the coolest. (A full list of the 50 metros is at the end of this post, and a ranking of all 361 U.S. metros is available for download here.)
