Yes, I experienced the mist on 11th August. It was really weird, almost spooky, and even blew into Porto Fino while we were having lunch. As has been mentioned, as soon as it disappeared it was absolutely scorching and very humid. However, it was early afternoon before it went.
Funnily enough it was hovering just above the sea the night before and I took a picture of it, never imagining what it was going to be like the following day.
