Odd.
The Rh gets very low - the 6% reading from 1913 seems kind of high to me. With the Rh that low, it does not feel as hot as it truly is, but things dry out unbelievably fast. The very low Rh seems to be one of the most noticeable things. My evaporative cooler could keep my apartment somewhat comfortable even if it was 120 degrees out. I also had an air conditioner but didn't need it unless I wanted quiet (the evap cooler was loud).
If one was in an air-conditioned building and stepped outside into heat like that, one would get goosebumps for a few moments, I think from the moisture in one's skin evaporating off quickly. If a person focused on maintaining hydration and electrolyte balance, and wore the right sort of clothing, a person could be surprisingly active in temps up to about 115 F. I could run a 5k in temps like that, it I planned and hydrated in advance, midway through, and could actively cool down afterwards (stand in front of blasting AC with an icepack on my head).
I would hang up my laundry to dry. Take a pair of socks out of the basket, put them on the line. Keep adding things from the basket. Once done, take the first pair of socks off the line and keep removing things in the order that they were put on the line. That worked for most lighter fabrics, but denim pants and other heavy fabrics might require as much as 15 minutes on the line to dry.
It looks different on the really hot days, smells different, and even sounds different - it seemed quieter to me above 120.
I grew up in fairly dry places, I would take a very dry 120 over a humid 95 any day.
