Yep, I was there. It makes me sweat when I think of it. The temperature was about 29°C (84 F) and you could not find any higher temperature in the rest of Europe at that time.
I was there primarily as a seller. Due to the hot weather, no-one was intested in buying (....or was it my useless stuff?). I sold for about $80 and that is really not much.
I took some hasty snap shots. Here they are.
