Sizzling Cities ranked – our new Heat Index

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.)

Top Ten Sizzling Cities (of the 50 largest U.S. metro areas)

Our Sizzling Cities ranking is certainly about comfort, but it’s also about safety.  For residents of all ages, extreme hot weather can be fatal.  Our Heat Index provides a way to predict how uncomfortable, and dangerous, summer in a city is likely to be.

According to the Centers for Disease Control and Prevention, over 650 people die annually from heat-related causes.  In developing the new heat index, my research team examined past patterns of these deaths to hone the accuracy of our model.

Besides the obvious risk to the ill and elderly, young healthy adults and teens can also die because they are unaware of the risk of exercising in hot, humid weather.  High humidity can be especially deadly because it prevents sweat from evaporating and cooling the body.

The Sperling’s Heat Index is unique in that it includes the nighttime low temperature in the calculation.  According to experts, a lack of nighttime cooling can be more dangerous than an extreme daytime temperature.  “Nighttime heat is especially bad,” said Eli Jacks, chief of fire and public weather services at the National Weather Service, “because your body never has a chance to recover.”

Because of the humidity, the heat in Houston feels nearly as extreme as that in Las Vegas, even though Houston has an average July high temperature over ten degrees cooler.  After the desert metros of Phoenix and Las Vegas, the nation’s top “hotspots” are found around the Gulf of Mexico, in the states of Texas, Florida, and Louisiana.

At the other end of the Sizzling Cities rankings are the Chill Cities, where residents can expect to enjoy a more comfortable summer than the rest of the nation.  As one might expect, Seattle, San Francisco and Portland are the three most comfortable places to spend the summer, followed by Denver, San Jose, and Buffalo.  These and other cool summer spots have a moderate high summer temperature, with cool evenings, and humidity that rarely becomes uncomfortable.

Here’s the full list of the 50 largest metro areas, ranked by the new heat index.

  1. How are the non daily-high’s incorporated into the calculation? It seems that cities like Tucson would feel cooler during more hours of a 24 hour period than say Miami because dry climates cool off much faster than humid ones, leaving a good portion of night and morning cooler. It would be my guess that Tucson feels hotter than Miami for 6-8 hours of the afternoon, but the rest of the time it would feel cooler. Having cool morning hours for a bit of outside work or a chance for heat relief is key for making it through those summer months.

    All of that is to say I would’ve expected the index to put southwestern cities lower.
    Thanks for putting out the list. Really interesting!

  2. Hi, Bert. I just found this page today and find it useful. I’m particularly interested in the spreadsheet showing all the data associated with your analysis but when I click on that link, I get a ‘not found’ error message.

    Any chance you might still have that data available, and be willing to share it with me/us?

    Thanks in advance for all you do re: weather analysis.

  3. While currently living in the Sacramento area, we are thinking of moving to Asheville, NC. We also briefly lived in Knoxville, TN. I’m just curious how much less oppressive the heat feels in Asheville, as compared with Knoxville? According to your list, Asheville is 5 degrees cooler in the summer. And I’m guessing (and hoping) that the nights cool off a little faster as well, considering you’re up in the mountains there. Thoughts?

  4. Hi Bert,

    Thanks for the valuable info. I would be curious to see monthly averages for various cities in addition to just the summer months. I live in the Minneapolis / St. Paul area and people think we have snow 8 months of the year! It certainly has warm summer days, but the seasons are a good break up throughout the year.

  5. Greetins,
    Your ranking of Sizzling Cities is Very Interesting and I am sure of great benefit to many people. As For Me- I am a Cool Climate Person Who Lives At An Altitude of 8,600Ft. In The Cool Rocky Mountains In Colorado. I Move To Colorado In The 1980s from the midwest because I hated the heat and humidity. And Now I Am Living A Comfotable Life In-Spite of The Amout Of Snow we Get Up Here In The Beautiful Rocky Mountains.
    Sincerely – A Colorado Resident

  6. Hi Bert,
    As you know, Im looking for a second home somewhere its a little warmer…and per your reccomendation: “..Maybe I can help you out with that “winter comfort” list when the time comes”…I would love any insights and suggestions you might offer…maybe similar type places…Im thinking lower oregon upper ca…by the water…any place near there youd reccomend…could you maybe describe the typical winter weather for that region…if ice common, Ill want to go further south…

    1. Hi Gregory,
      Here are some thoughts. Southern Oregon, south of Eugene is hotter in the summer, cooler in the winter, and also drier than the Willamette Valley cities to the north (Portland, Salem , Eugene, Corvallis, Albany). Ashland is especially sophisticated but pricey for that part of the state, and nearby Medford is nice. Roseburg, Grants Pass and Klamath Falls are all smaller than Medford and nice alternatives for an unpretentious small town lifestyle.
      As you get into California, you get into the mountains of the Shasta National Forest. There you’re getting into serious winter snowfall in the towns of Weed, Shasta, and Dunsmuir. I especially like the crags and peaks around Dunsmuir, but I imagine the winter weather could be overwhelming at times. As you leave the forest and descend into the northern end of the state’s Central Valley, you trade the winter snow for some truly breathtaking summer heat in Redding (100 deg average in July).
      Just remember there are plenty of town located in the high desert, where the temperature often dips below freezing at night but snow and ice is a rarity because it’s so dry.
      Good luck with your search,
      Bert

  7. I really like your new “Sizzling Cities ranked – our new Heat Index”…I live in Buffalo and love the summers here…not too crazy about the winters though…looking for a second home somewhere its a little warmer (in the US winter)…so basically the same list only showing the avg winter “heat index” of cities…

    1. Hi Gregory,
      Thanks for the info! Data can provide some insight but there’s nothing like real ‘feet on the street’ reporting. I rely on feedback like yours to help decide if I’m on the right track in developing our analytical models.
      I’m glad you mentioned winter comfort because I’ve been playing around with an index for that. I think this is more difficult because basically nobody likes when then temperature gets into the 90’s and it’s humid. But some people love some snow in the winter, and don’t mind the cold. Others tolerate the gloomy drizzle of the Northwest with mild temps that rarely get below freezing. And many people can’t stand when the temperature dips below 60. So it seems to me that it’s hard to pick the ideal winter climate.
      What are your thoughts? Maybe I can help you out with that “winter comfort” list when the time comes.
      Best,
      Bert

    2. cant wait to move to Colorado!!! This Louisiana heat and humidity is unbearable. Can’t imagine what it’s like to go outside and not perspire beginning in April-October!
