Still talking about the weather
Well folks, I did it. I remembered I had sunscreen at work, so I could at least prevent my skin from incinerating, applied it liberally and set off from work. My phone actually told me it was 42 degrees, so that is what I am saying. See:
(This is my proof that at 5.57 pm it was 42 degrees. I took the picture at 6.22 pm when I got home before updating the weather, to keep the proof. It's now dropped back to 40 degrees.)

The sun was actually mostly behind some clouds, there was a slight breeze blowing, and the humidity was only about 16%, so it really was not as bad as I thought it might have been. You could hardly tell you were sweating because the sweat evaporated from your skin and vanished so quickly.
It reminded me strangely of the years of my youth. I grew up in an inland country town, where temperatures were regularly high in the summer (and frosty in the winter), but it was a dry heat, and I still prefer 42 in a dry heat to 32 swamped in humidity.
