I seriously doubt El Paso is as humid as it is portrayed. And I know Greenville, SC, second place in this silly listing, is not nearly as unpleasant in the summer as is Columbia, which didn't rate a mention.
Greenville, in the foothills of the Blue Ridge, is about 1050 feet above sea level; Columbia, 100 miles southeast of Greenville, is close to some serious swamps, and is 190 feet above sea level. Average hi/lo July temps in Greenville are 88/68; in Columbia, 92/70. The site I went to didn't have humidity stats, but I'd bet Columbia's humidity is higher. Columbia is absolutely one of the most miserable places in the summer (the weather, I mean; the people are nice) I've ever encountered. No way Greenville is worse.
Hmmm...
My vote goes to Charleston. The 2 years I was stationed there, the average heat index in the summer had to be in the 105-110 degree range. I think it's worse than Tampa, were I live now.
But I think the dampest place I've ever been had to be Baton Rouge in late July. Ick.....
I spent most of a summer in Greenville about 15 years ago. I loved the place and thought that it was a whole lot more pleasant than Dallas in the summer.I've been to El Paso plenty of times. Yes, it's a hellhole unless you're in one of the better parts of town but I found the climate somewhat desert-like and, of course, not as bad as Dallas.
Houston and the surrounding environs are totally unbearable in the summer.
