Not disagreeing with what you say, but unless I'm remembering incorrectly ( and that could be a distinct possibility) last summer did not seem terrible at least as far as temps compared to the few before. For me I still think summer 2018 was THE worst as far as combination of extended heat along with high dews. It could be simply because it was a memorable summer for me preparing for my wedding in September, however the weather just seemed terrible and broke just in time for our outdoor wedding. Only time in my life I've ever felt the effects of heat stroke or whatever you call it. Feeling dizzy and shaking uncontrollably... It Came Upon me out of nowhere. NOT a fun experience
