I was working outside this week (Southern US) and it was an absolutely miserable week. After a half an hour I was drenched in sweat, and it was rolling off my hard hat, getting in my eyes, and I was forced to pace myself and work much slower than I would otherwise be able to do because the heat was that intense.
I was able to drink some of my coconut water reserve because it has the things plants crave.
It's definitely the worst summer heat I've felt since ever.
