Mid-South heat...Is it really hot or just humid?


2014 was the hottest year on record globally. The ten hottest years on record have all occurred since 1998. So far, the summer of 2015 has been very humid in Memphis and the Mid-South but we haven't seen record-breaking heat. We haven’t broken one record high yet and we haven’t even hit 100º. We made it to 99º on July 20th, so we have been close. Take a look at the number of days we have hit 100º or higher in the graph below. We had a really hot period from 1980 to 1985 with over 35 days at 100 or higher. The trend went down through the 80s and 90s and then back up in the 2000s. Now we are in a downward trend again. 

Last summer was cooler and wetter and we only hit 100º once. We didn’t hit it at all in 2013 but we hit 100º ten times in 2012. Overall, it’s rare to not hit 100º at least once each summer in Memphis. We’ve been flirting with it a lot this summer and I would be surprised if we don't hit 100º at some point in August. Even though we haven’t seen the actual temperature hit the century mark, it has felt like 100 - 105º consistently this month thanks to those higher dew point temperatures. That's right, the dew point, not the humidity. That will be my next blog. Stay tuned and stay cool!
