Only in the upper 80s (F) here, but there's no breeze and not a cloud in the sky, and the sun is
brutal. I was on the deck for a while, wearing a shirt with metal rivet buttons and every once in a while I'd shift my position and one of those hot buttons would touch my skin!
On the other hand, I just got a solar-powered "power bank" and it has already soaked up enough sun to light up two more LEDs on it's bar gauge.
